Starts a VDA Tool used for plotting a 3D bar chart.

var — The name of a 2D variable, with a maximum size of 200 by 200.

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 (horizontal and vertical) 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.

The var parameter is a 2D array of elevation values. The 3D effect is established by modifying the colortable to create darker color values for use on the top and left sides of the bars. By default, the bars are displayed vertically (upward).

The Parent keyword is used to connect WzBar3D 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 WzHistogram in:

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.
