ContourResetExtents macro command

Print this Topic Previous pageReturn to chapter overviewNext page

Macro commands may be used either in macros or by sending the commands to DPlot via dynamic data exchange (DDE). Some commands are valid only in macros (noted by Macros Only). Commands sent to DPlot via DDE must be enclosed by square brackets [     ]. Macro commands should not include the brackets.

Command parameters shown in the descriptions below are placeholders for the actual values. Command parameters are either numeric values, equations that evaluate to numbers, or character strings. Character string parameters are always bound by double quotation marks. Equations must be preceded by an equals sign (=).

The pipe symbol (|) in the command syntax indicates that a parameter is optional, and should not be included in your macro unless otherwise noted.

All indices into arrays are 1-based, e.g. Curve1=1 refers to the first curve in a plot.

A 0x prefix for numbers in the descriptions below indicates hexadecimal notation; e.g. 0x0010 = 16.

JR/Viewer indicates that the command is supported by DPlot Jr or DPlot Viewer.
JR/Viewer indicates that the command is NOT supported by DPlot Jr or DPlot Viewer.


 

[ContourResetExtents(state)]

JR   Viewer

If state is non-zero then DPlot will automatically adjust the lower and upper contour limits when you zoom in/out and/or force the plot extents by using the Extents/Intervals /Size command on the Options menu. In this case the specified number of contour intervals set with ContourLevels will be used as a guideline; the actual number used may be slightly more or less. If you zoom in to such an extent that only one data point is visible, or if all visible data points have the same magnitude, the lower and upper limits will be forced to that value +/- 5%, or +/- 0.5 in the case of Z=0. A non-zero state is equivalent to checking the Use actual displayed limits box on the Contour Options dialog.

If state is 0, the specified lower and upper contour limits will be used regardless of the displayed extents.
