Overview Control

The overview control is placed at the bottom of an existing chart or grid. It is used to control the zoom interval and to scroll back and forth through the data. The sliding window on the overview component establishes what can be seen in the detailed chart or grid.

To activate the overview control:

  1. Select any statistic in the chart/grid. A context menu opens.
  2. Select Show/Hide Overview. The overview chart appears just above the view tool bar.

    You can resize the overview window by dragging the handle just below the overview pane.

The buttons attached to the overview control chart are described in the following table.

Description

Predefined Zoom Steps

Select this button to open a pop-up menu:

Min: This is the minimum time interval for zooming. It is about five minutes if the polling is made every two seconds, and about two and half minutes if the polling is set to one second.

Max: This is the maximum duration for which the test was run. In addition, depending on the test duration the application maintains some automatic intervals (for example, 30 minutes, one hour, four hours, and so on).

Available Iterations

Select this button to open a pop-up menu showing the list of result sets/groups defined for the current view.

The available iterations for a view are available and displayed in the pop-up menu.

If the window is empty, then selecting this button displays a dialog with the “No iteration available to compare” message.

You must enable the Show/HideIteration Markers button before running a test in order to load a test for comparing iterations.
