WzHistogram Overview
The WzHistogram Tool is used to visualize quantitative trends in large amounts of 1D, 2D, or 3D data. You can create a histogram for any non-scalar variable of these types:
note | Not all of the data can have the same value. For example, a 2D array of zeroes is unacceptable. |
Specify the name of a variable at the WAVE> prompt when you start the WzHistogram Tool.
note | Avoid using the PV‑WAVE DEVICE command at the WAVE> command line when VDA Tools are running. |
WzHistogram Features
The WzHistogram Tool offers options for enhancing the appearance of the histogram. For instance, you can use color to highlight your data, and the VDA Tool’s graphical features allow you to annotate the histogram with lines, rectangles, ellipses, and text. You can change the range of data in both the X and Y directions.
