Can I insert a scale break?

Yes. You can place one or more true scale "breaks" in a graph axis in order to "cut out" (i.e., "compress") certain areas of the graph space:

To do this, right-click on the axis in which you want the break to appear and select Scaling from the shortcut menu. In the resulting Scaling dialog, click the More button and add a new break by clicking the Add new scale break button.

Use the From and To boxes to adjust the break location. STATISTICA will place the break in the specified location of the scale after you click the OK button on the Scaling dialog. These options are also available in the Axis: Scaling options pane of the Graph Options dialog. Note that you can add more than one scale break to an axis.
