157) Has anyone done a bar graph widget?

[Last modified: September 92]

Answer: You can fake one by using for each bar a scroll bar or even a label
which changes in size, put inside a container of some kind.

Try the StripChart widget in the Athena widget set. Set the XtNupdate resource
to 0 to keep it from automatically updating.

The comp.windows.x FAQ mentions a bar graph widget.
