I would like to add a highlight mechanism to my chart. For a simple line plot, what approach would you recommend to produce a different background color for the section of the chart between two given x values.
For example I would like to use the standard background color except when X is between 16 and 22, then I would use a different background color. Is such behavior possible perhaps using a very wide vertical line and a transparent color?

I think I found my starting point in the Multiline class of the examples.multiline package.

Use the ChartShape class to display a filled rectangle in the current chart. The Multiline.MultilinePlots example is the correct one to look at.
