Determining the Interval Limits for a Color Palette
1.If the diagram is in a document or a worksheet, double-click on the diagram to open it.
2.Double-click on the curve or its axis label with the color palette interval limits that you would like to change.
3.In the dialog box that appears, click on the Connection Line, Grid Lines or Fill tab.
4.In the Form palette intervals with field, specify whether the palette intervals are to be predefined by the divisions of the corresponding axis or by a data set. Linking the palette to the axis division is only possible with linear or logarithmic scaling.
5.If you would like to specify a data set, enter its name in the Data Set field. You can also enter an FPScript expression that calculates a data series directly in the field.
Note: Since the two outer intervals are open intervals, the data set must contain only n-1 interval limits for n intervals.
