This image shows the Log Explorer page from Logging Analytics.  The top right of the image contains a dropdown to select the timespan for log exploration. The last eight hours is chosen in this screenshot.  Next to the time selector is an Actions dropdown where queries can be saved, recalled, exported and more.
Next down, the query bar provides a SQL-like syntax for retrieving records, performing operations on the results, and defining how to display them.  To the right of the query bar is the Run button to execute the query.
Below the query bar are the Fields pane, the Visualization pane, and the main query results pane.  
The Fields pane shows Pinned fields, Computed fields, and Other fields which are parsed from the queried log records as well as a Search field to find a field name of interest.  These fields can be used for filtering or can be dragged into the Visualization pane.
The Visualization pane contains a dropdown to select the type of visualization preferred for the query results.  This image shows Records with Histogram as the chosen visualization.  Below the dropdown are the primary and additional display fields which have been selected. Finally, entry fields allow selection of the X-Axis value (Time) and Group By field (stacked bars).  The Apply button applies the selected changes to the visualization.
The bottom of the Visualization pane shows Display Options which allow for selection to Show Problem Logs Only, Show Log Scale, or select the number of records shown per page.
The main query results pane displays the results of the query, using filtering and display options chosen from the Fields and Visualization panes.  In the top of this page, a stacked bar histogram shows the counts of log records in ten minute intervals, grouped and colored by the Log Source.  To the right of the histogram, the legend shows the Log Source for each color along with the total count of that Log Source within the overall count.  In the lower part of the pane, a table shows log records with their time stamp, original log content, and fields selected from the Fields pane.
