Opacity of RGB colored area graph

[Felix Koenig]

Can I set opacity if the color is RGB defined (in area graphs)?

The following command doesn't make the area transparent.

twoway  rarea y1 y2 year, color("222 235 247"%30) xline(1941, lpattern(dot))

If I replace the color command by "color(blue%30)" it works as expected.

Welcome to the Statalist, Felix.

See -help colorstyle- for full details of how to specify opacity. All you have to do in your case is move the “%30” inside the quoted string, like so:-color(“222 235 247%30”)-.
