WzPlot Procedure

Starts a VDA Tool used for 2D plotting.

Usage

WzPlot, var₁[, var₂, ..., var_n]

Input Parameters

var_i — The name of the 2D variable to plot or an equivalent expression.

Keywords

Independent — Specifies the name of the variable to be taken as the independent variable.

NoBlock — If specified, the event loop (WwLoop) that is started by the VDA Tool will use the given value. By default a value of 1 (non-blocking loop) will be used. However, it may be necessary in certain circumstances to force a non-blocking loop by specifying NoBlock = 2. (See WwLoop in the PV‑WAVE Application Developer’s Guide for more information.)

Parent — The widget ID of the parent widget.

Position — Specifies, in pixels, the x and y coordinates for the starting location of the upper-left corner of the VDA Tool window.

Restore — A data structure previously saved in the Tools Manager with the TmSaveTools function. This keyword is reserved for internal use; it is not to be used at the command line (see Discussion).

Template — A string containing the name of a VDA Tool template file.

XSize — Specifies, in pixels, the width of the drawing area.

YSize — Specifies, in pixels, the height of the drawing area.

Discussion

The maximum number of variables you can plot simultaneously in a WzPlot tool is 10.

The Parent keyword is used to connect WzPlot to another application, such as the Navigator.

The Restore keyword is used specifically by the TM_RESTORE method. For information on the TM_RESTORE method, refer to the source code for WzPlot in:

<wavedir>/lib/vdatools/wzplot.pro

<wavedir>\lib\vdatools\wzplot.pro

Where <wavedir> is the main PV‑WAVE directory.

A template is a VDA Tool without any data associated with it. The template contains all of the modifications to the VDA Tool — colors, axes, graphical elements — that were set when the template file was saved. Template files are saved with the Save Template As command from the File menu on the VDA Tool.
