3 Graph Displays

Graphs appear in the Main Window of the following types of screens:

• Dashboard

• Overview

• Analysis

This section describes the types of graphs available on Overview and Analysis screens and provides instructions for modifying their appearance and the data they display. The following topics are discussed:

• Areas of the Main Window

• Types of Graphs

• Graphs on Overview Screens

• Graphs on Analysis Screens

• Best Practices for Graph Displays

• Graph Display Tasks

• Data Graphing Tasks

Areas of the Main Window

All STA Overview and Analysis screens follow the same general structure and layout. The Main Window is divided into a Graphics Area at the top, and a Table Area at the bottom. The border between the two areas is marked by the Collapse Pane icon, which is always visible, and the Resize control bar, which appears when you move the mouse over the space between the two areas.

STA has two types of graphics screens: Overview and Analysis. This section describes graph characteristics and tasks shared by both screen types. See the following sections for characteristics unique to each type.

• "Graphs on Overview Screens"

• "Graphs on Analysis Screens"

Types of Graphs

This section describes the types of graphs used in STA. It also describes actions you can perform to get the most information from the graphs.

• "Line Graphs"

• "Area Charts"

• "Bar Charts"

• "Pie Charts"

• "Spark Charts"

Line Graphs

Line graphs are used to compare actual values for one or more resources over a period of time. Each line represents a resource (drive or media) or other category of data. Time is always shown on the horizontal axis. Each point on the line represents an actual value at a point in time. There must be at least two data points available for a line graph; if there is only one data point, the graph will display as a bar chart.

Note:

The default date range for most STA line graphs (libraries, complexes, drives, and media) is the last 30 days. For exchanges, the default is one day—the current date.

User Action	Description
Display detailed values	Move the mouse over a point in time on a line to display the specific value in a tooltip. Other lines on the graph are dimmed. Description of the illustration ''if_linedetail.png''
Highlight values	Move the mouse over an area of the legend to highlight that line on the graph. All other lines remain on the graph but are dimmed. Description of the illustration ''if_linehighlight.png''

Area Charts

Area charts are used to compare percentage values for two or more resources over a period of time. An area chart is similar to a line graph, but in addition, the area under the line is filled in with a color or pattern. Each line represents a resource (drive or media) or other category of data, and the size of the area under the line represents the resource's percentage of the total. Time is always displayed on the horizontal axis. Each point on the line represents an actual data value at a point in time.

Note:

The default date range for most STA area charts (libraries, complexes, drives, and media) is the last 30 days. For exchanges, the default is one day—the current date.

User Action	Description
Display detailed values	Move the mouse over a point in time on a line to display the specific value in a tooltip. Other sections on the graph are dimmed. Description of the illustration ''if_areadetail.jpg''
Highlight values	Move the mouse over an area of the legend to highlight that section on the graph. All other sections remain on the graph but are dimmed. Description of the illustration ''if_areahighlight.jpg''

Bar Charts

Bar charts are used to display actual values for one or more resources at a point in time. Each bar represents a resource (drive or media) or other category of data, and the size of the bar represents the resource's actual value.

User Action	Description
Display detailed values	Move the mouse over a bar to display the specific value in a tooltip. Other bars on the graph are dimmed.
Link to a detail screen	Note: This action is available from the Dashboard only. Click an area of the bar to link to the detail screen for that resource type; in this example, the link is to the Drives –Overview screen. The List View table on the screen indicates that a filter has been applied: Description of the illustration ''if_barlinktarget.png''
Highlight values	Move the mouse over an area of the legend to highlight that entry in the graph. All other entries remain on the graph but are dimmed. Description of the illustration ''if_barhighlight.png''

Pie Charts

Pie charts are used to compare percentage values for two or more resources at a point in time. Each section of the pie represents a resource (drive or media) or other category of data, and the size of the section represents the resource's percentage of the total. To be meaningful, pie charts require graphing at least two resources, as only one resource will take up all of the pie.

User Action	Description
Display detailed values	Move the mouse over a section of the pie to display the percentage value in a tooltip. Other sections of the pie are dimmed. Description of the illustration ''if_piedetail.png''
Link to an Overview screen	Note: This action is available on the Dashboard only. Click a pie section to link to the Overview screen for that resource type; in this example, the link is to the Drives –Overview screen. The List View table on the screen indicates that a filter has been applied: Description of the illustration ''if_pielinktarget.png''
Highlight values	Move the mouse over an area of the legend to highlight that entry in the pie chart. All other entries remain on the chart but are dimmed. Description of the illustration ''if_piehighlight.png''

Spark Charts

Embedded spark charts are included in some Dashboard table portlets (see the STA User's Guide for table portlet descriptions). A spark chart is a small line graph that plots up to four key values—Start, End, High, and Low—for a selected date range. Spark charts can help you to see patterns in data values over time.

Depending on the date range selected and the variation among the key values, a given chart may have only two or three dots plotted, rather than four. This is because the dot for one value may hide the other if two key values are close in date and value. Filtering for a shorter date range may reveal more detail.

Figure 3-1 through Figure 3-3 show three different date ranges for the same Dashboard portlet. Because all three ranges use the current date as the end date, the End Values are the same for all. The other key values vary, however, as the start date and relative high and low values are different for each range.

Graphs on Overview Screens

The Graphics Area of Overview screens consists of the Graphics Area Toolbar and one or more graph panes. Each graph pane also has a Graph Pane Toolbar. When multiple graph panes are displayed, they are tiled, up to three per row. You can display up to 15 graph panes at a time.

You can modify the data displayed on individual graph panes through any of the following actions:

• Change the displayed attribute; see "Graphed Attribute" below for details.

• Change the displayed date range; see "Date Range" below for details.

• Switch between real and percentage values; see "Real and Percentage Values" below for details.

• Add individual resources to the graph for direct comparison; see "Individual Records" for details.

Graphed Attribute

Each graph pane displays values for exactly one drive or media attribute. You can change the displayed attribute by clicking the Change Graphed Attribute icon on the Graph Pane Toolbar and then selecting any of the available attributes for that resource type.

See "Change the Graphed Attribute" for detailed instructions.

Date Range

By default, most graph panes display values for the previous 30 days. This is a rolling time period which is updated daily. The exception to this is the graph panes on the Exchanges Overview screen, which display values for the current date only.

You can change the date range by clicking the Choose Date Range icon on the Graph Pane Toolbar. You can then specify new start and ending dates for the range or a point in time (one day). Date ranges longer than one day are displayed as line graphs. Point-in-time graphs are displayed as bar charts. See "Change the Date Range" for detailed instructions.

Once you have specified a new date range for an individual graph, you can apply that range to all graphs on the screen by clicking the Synchronize Date Range icon. See "Synchronize a Date Range Across All Graphs" for detailed instructions.

Real and Percentage Values

By default, the graph panes display actual data values. You can optionally switch to a percentage display, which shows individual resource values as a percentage of the whole. Actual values are displayed as a line graph, and percentage values are displayed as an area graph.

You can switch between actual and percentage value displays by selecting the Show Percentages icon on the Graph Pane Toolbar.

See "Switch Between Actual and Percentage Values – Overview Screens" for detailed instructions.

Units of Measure

Units of measure are identified on the horizontal and vertical axes of each graph pane. On line and area graphs, which show values over time, time is always shown on the horizontal axis, and the attribute values are shown on the vertical axis. The scale of both axes automatically adjust to provide a useful amount of detail for the values included in the graph.

If the graphed attribute includes a unit of measure, such as MB Read, then the total value of a given data point is the product of the unit of measure included in the attribute multiplied by the unit of measure of the vertical axis. The sample graph panes shown below use different units of measure on their vertical axes.

• In the MB Read graph, the highlighted data point indicates a value of 88.59K. Because the vertical axis is measured in megabytes, the value of the data point is actually 88.59K megabytes, or 88,590 MB.

  
  Description of the illustration ''if_gruommultiplier.jpg''
  
  

• In the Dismounts graph, the highlighted data point indicates a value of 2,061. Because there is no multiplier on the vertical axis, the value of the data point is actually 2,061.

  
  Description of the illustration ''if_gruomnomult.png''
  
  

Individual Records

When you first start an Overview screen, the graph panes display only the system average for their selected attribute. You can compare individual resources to each other and the system average by adding the resources to the graphs. You add individual resources by selecting their records on the List View table, and then applying the selection to the graphs. The individual values are then highlighted on the graph, and the system average is ghosted.

You can change the displayed resources simply by selecting different ones and re-applying the selection. If there is no data for a selected resource, no values will appear on the graph, but the resource will be added to the graph key to indicate that it has been selected. When you leave the Overview screen, the selections are cleared, so that when you return, the graph panes again display the system average only.

To clear all resources from the graphs without exiting the screen, you can deselect all records on the List View table, and then re-apply the selection to the graphs.

See "Add Library Resources to Graphs" for detailed instructions.

Best Practices for Graph Displays

This section provides tips for using the STA graph displays.

Hiding graphs

The graphs at the top of most Overview screens are often not needed. Use the Collapse Pane button between the graphs and the table to collapse the graphs and make more space for the table. You can save this view as a default template so it is easily applied to the screen.

See "Collapse and Restore the Graphics Area".

System average

The dotted black line shown by default in all graphs shows a summary or average across your tape library system. This provides a good comparative baseline.

See "Individual Records".

Displaying individual values

You can add specific resources (drives, media, and so on) to the graphs by multi-selecting them from the table, and then clicking the Apply icon. This is a powerful tool for comparing resources within your tape library system.

See "Add Library Resources to Graphs".

Synchronizing graphs

You can synchronize date and time ranges on the Overview screen graphs by clicking the Synchronize Date Range icon on each graph. This provides a good way to compare resources across multiple data ranges—you can change the date and time range in one graph and then synchronize the other graphs to it.

See "Synchronize a Date Range Across All Graphs".

Graph Display Tasks

These procedures allow you to modify the appearance and arrangement of graphs on the STA screen. Some tasks apply to both Overview and Analysis screens, while others apply to Overview screens only; this distinction is identified at the top of each procedure.

• "Detach a Graph Pane"

• "Rearrange Graph Panes"

• "Add a Graph Pane"

• "Remove a Graph Pane"

• "Switch Between Narrow and Wide Views"

• "Perform a Graph "Quick Print""

Detach a Graph Pane

Note:

This procedure applies to both Overview and Analysis screens.

Use this procedure to separate a graph pane from the Graphics Area and display it in a separate window in the browser foreground. Once you have detached a graph pane, you can resize it and move it anywhere within the browser window. You can detach only one pane at a time.

1. Click Detach Pane in the Graph Pane Toolbar.

   
   Description of the illustration ''if_graphdetach.jpg''

2. Click and drag the pane to its new location.

   
   Description of the illustration ''if_grpanemoving.jpg''
   
   

3. Once the pane is near the position you want, release the cursor.

   The pane snaps into place. You do not need to position it exactly.

   
   Description of the illustration ''if_grpanemoved.jpg''
   
   

Add a Graph Pane

Note:

This procedure applies to Overview screens only.

Use this procedure to add a graph pane to the screen. Data is displayed in the new graph according to the following criteria:

• The graph displays the default attribute for the resource type. For media, the default is Data Mounts; for drives, it is MB Read. You can change the attribute to any available attribute for the resource.

• If the existing graph panes have all been synchronized to the same date range, the new graph uses the same one; otherwise, the graph uses the system default date range of the previous 30 days.

• The new graph displays actual values, even if all the existing graphs display percentages.

• If individual resources have been applied to the existing graphs, the new graph displays the same ones.

1. Click Add Graph on the Graphics Area Toolbar.

   Note:

   You can display up to 15 graph panes at a time; once you reach 15, the Add Graph icon is disabled (dimmed).
   
   Description of the illustration ''if_graphadd.jpg''
   
   

   The graph pane is added to the end of the Graphics Area display. You may need to use the vertical scrollbar to view the graph.

   • To move the pane to a new position, see "Rearrange Graph Panes".

   • To graph a different attribute, see "Change the Graphed Attribute".

Remove a Graph Pane

Note:

This procedure applies to Overview screens only.

Use this procedure to delete a graph pane from the Graphics Area display.

1. Click Remove Pane on the Graph Pane Toolbar.

   
   Description of the illustration ''if_grremove.jpg''
   
   

   The pane is removed from the display.

   See "Add a Graph Pane" for instructions on restoring the graph pane to the display.

Switch Between Narrow and Wide Views

Note:

This procedure applies to both Overview and Analysis screens.

Use this procedure to display graphs in narrow and wide formats. Narrow view is the default, and it allows you to do side-by-side comparisons of graphed attributes. Wide view allows you to see each graph in greater detail.

1. Click Wide View on the Graphics Area Toolbar.

   
   Description of the illustration ''if_grwideview.jpg''
   
   

   The display changes to wide view, in which each graph pane is expanded horizontally across the entire Graphics Area. A vertical scrollbar appears, allowing you to scroll down to the remaining panes.

   
   Description of the illustration ''if_grwide.jpg''
   
   

2. To switch back to narrow view, click Narrow View in the Graphics Area Toolbar.

   Description of the illustration ''if_grsyncdone.jpg''
   
   

Add Library Resources to Graphs

Note:

This procedure applies to Overview screens only.

Use this procedure to add selected library resources—such as libraries, drives, media, and so on—to all graph panes on the screen. In the default view, graphs display only the system average for the graphed attribute.

1. In the List View table, select one or more resources.

   Note:

   You can use multi-select to select more than one resource; see "Multi-select" for details.
   
   Description of the illustration ''if_grselectres.jpg''
   
   

2. Click Apply Selection on the List View Toolbar.

   
   Description of the illustration ''if_grapplyselection.jpg''
   
   

   The selected resources are added to all graph panes on the screen.

   Note:

   Depending on the data values for the selected resources, the scale of one or more graph panes may change. The scales of the horizontal and vertical axes automatically adjust to show a useful amount of detail for the selected resources.
   
   Description of the illustration ''if_grselectapplied.jpg''
   
   

3. You can change the selected resources, as follows:

   • To remove these resources and add different ones, repeat Step 1 and Step 2, this time selecting different resources.

   • To remove all resources from the graphs and display just the System Average, deselect all the selected resources in the table and click Apply Selection again.

Switch Between Actual and Percentage Values – Overview Screens

Note:

This procedure applies to Overview screens only.

Use this procedure to switch between actual and percentage values on a graph pane. Actual values are displayed by default. Percentage values compare individual resources within a set of selected resources; therefore, displaying percentage values is useful only when at least two resources have been added to the graph.

1. Add two or more resources to the graph. See "Add Library Resources to Graphs" for detailed instructions.

   
   Description of the illustration ''if_grmediaapplied.jpg''
   
   

2. Click Show Percentages on the Graph Pane Toolbar.

   
   Description of the illustration ''if_grshowpercent.jpg''
   
   

   The graphed values change from actual to percent, and the line graph changes to an area chart.

   
   Description of the illustration ''if_grpercentvalues.jpg''
   
   

3. The Show Percentages icon acts as a toggle. You can click it again to switch back to actual values.

Switch Between Actual and Percentage Values – Analysis Screens

Note:

This procedure applies to Analysis screens only.

Use this procedure to switch between actual and percentage values on a graph pane. Actual values are displayed by default. Percentage values compare individual resources within a set of selected resources; therefore, displaying percentage values is useful only when at least two resources have been added to the graph.

Graph Detail for a Pivot Table Attribute

Note:

This procedure applies to Analysis screens only.

Use this procedure to graph detail data for a pivot table attribute. This results in just one graph pane in the Graphics Area.

Note:

You can graph attributes that appear on the row edge only, and only one row at a time. If you select a column edge attribute, or if you select multiple rows, you will see the error, "Please select one and only one row."

1. In the pivot table, select a row that shows one value for an attribute.

   Note:

   In this example, the "HP" value for the Drive Manufacturer attribute is selected.

   The selected attribute value is displayed in a single graph pane.

Graph Aggregated Data From a Pivot Table

Note:

This procedure applies to Analysis screens only.

Use this procedure to graph aggregated data from a pivot table. This results in multiple graph panes in the Graphics Area: one for the aggregated totals and one each for the attribute values included in the totals.

Note:

You can graph attributes that appear on the row edge only, and only one row at a time. If you select a column edge attribute, or if you select multiple rows, you will see the error, "Please select one and only one row."

1. In the pivot table, select a layer that aggregates multiple attribute values.

   Note:

   In this example, the nesting layer is "Library Number", which aggregates data for two drive manufacturers: "HP" and "STK".

   The Graphics Area is updated as follows:

   • The left-most pane shows the summary data for the attribute.

   • The panes to the right show detail for each attribute included in the aggregation, one pane per attribute. In this example, there are two detail panes: one for "HP" and one for "STK".
