DPlot

Hello.

I want to change the color background only in one area defined by two reference lines, one ref. line with some X value and another ref. line with some Y value.

I try Fill between curves but I did not find the X values only Y.

Regards

The only way to do this currently is to make 2 curves with your constant X and constant Y values, then "Fill Between Curves". You'll use two fills, one for the constant X with the "2nd Curve" set to Left or Right, the other fill for the constant Y curve and the "2nd Curve" set to Top or Bottom. Check the "Draw only the intersections of all curves" box.
