[vtkusers] Show units in tooltip

[Eric E. Monson]

Hey Martin,

It depends on which version of VTK you're using. If you're using 5.8 or the development head then look at vtkPlot:: SetTooltipLabelFormat(). I haven't tried it yet, but it should let you customize the tooltip text with a printf-style string.
