5.3. Stacked plots

When marked group plots are made using the purple plot buttons, the default behavior is to overplot the various data groups. At times, it might be preferable to place an offset between the plots. This is done in general by setting the «y-axis offset» parameter. Stacking plots in a systematic manner is done using the stack tab. Stacking is done by setting the «y-axis offset» parameters of the marked groups sequentially.

This tab contains two text entry boxes. The first is used to set the «y-axis offset» parameter of the first marked group. Subsequent marked groups have their «y-axis offset» parameters incremented by the amount of the second text entry box. Clicking the Apply to marked button sets these values for each marked group.
