Advanced chart or plot features

I’d like to create a histogram with vertical line markers for upper and lower range cutoffs. I don’t know how I can create the vertical lines. Another thing I noticed is that the widths of the bars in the bar chart don’t change as the size of the chart changes.
Is there documentation I can look at for advanced chart features like this, or can anyone suggest how to handle these features?

See what you can do with VTK charts in this presentation:

Probably the simplest would be to use “selection” for using different colors for inside/outside cut

Thanks, I’ll read through the presentation, and see what I can do.
