SetFillStyle with TGraphErrors

Dear rooters,

I’m trying to use SetFillStyle(3004) with a TGraphErrors and would like to make the line shading darker. I tried doing this with


but I believe this doesn’t work for the 3004 fill style. There’s no crash; the lines just don’t change. In my list of directives I’ve included AtlasUtils.C. Does anyone have an idea on what the problem is?

answer here:

This is the first place I looked. I’ll take another look, but this page doesn’t seem to be too helpful.

it says:

This is what I originally thought, except the figure below has the same pattern but with thicker lines than the one I’m trying to make, which made me think differently. I guess it might be something to do with the .pdf conversion.
