Zooming and Scrolling in Graphs

If zooming and scrolling has been enabled for a graph, then the graph includes a Zoom icon. The zoom icon enables you to zoom in and out of a graph's plot area using its axes. Once you zoom in on an axis, you can scroll the axis.

To enable zooming and scrolling in a graph, the content designer sets the zoom and scroll properties in the "Graph Properties dialog: General tab".

When you zoom an axis, a zoom and scroll slider is displayed.

A zoom and scroll slider consists of the following components:

• Left or bottom button — Scrolls to the left on the X axis or to the bottom on the Y axis, revealing portions of the graph that are out of view.

• Right or top button — Scrolls to the right on the X axis or to the top on the Y axis, revealing portions of the graph that are out of view.

• Scroll thumb — Represents the visible portion of the graph in relation to the full graph. You drag the scroll thumb to dynamically scroll the graph, revealing portions of the graph that are out of view.

• Resize handles — Are displayed at each end of the scroll thumb when you hover over the thumb. You use the resize handles to zoom in and out an axis.

• Tooltip — Is displayed only when a user hovers over either the thumb or a resize handle and describes the data that is currently displayed in the scroll thumb.
