How to generate a gradient colored legend after a custom graph in Stata?

This is a re-post. Somehow I have been unable to see my first post. I apologize for that.

To simplify matters: let's suppose one has a scatter plot as follows:

 clear set  obs 10  gene x = _n  gene y = _n  scatter x y, xsize(8) aspect(0.7)

which will look like this:

The idea is to plot on the left-hand side a custom gradient bar. For example:

I haven't figured out something straightforward that generate that gradient colored legend. Does anyone have experience with that? Any suggestions?


All the best,

To the best of my knowledge there isn't a way to map a gradient to values in the way I think you are wanting to. You'd either have to define distinct groups for each of your points and then map each point to a color, or might be able to make contourplots do something to provide some type of related output.

Thank you, William.

I thought I could do that using colorpalette:

colorpalette, vertical: DarkCyan White, ipolate(10) / #bd1e24 White , ipolate(10)

Manually editing the graph to change its size and then using -combine- to combine both graphs. However, colorpalette has no ysize() xsize() options

Any thoughts are welcome.

All the best,

Tiago
