Added the options that weren't explicit in my plot command

@ciao That works sort of, but then it makes the mesh lines too dark for values near Opacity[1] (i.e., darker than they were in the original).

If the plot is produced as described, plot/. GrayLevel[__] -> Opacity[n] where plot, n are symbol of plot and desired opacity is a QND way to get it done.

| Jul 1, 2016 at 1:12 | comment | added | glwhart | @Jens: Intended application? I want to make a GraphicsRow of some 2D basis functions. I want to "weight" their contribution to an eigenfunction by their opacity. So the plots that don't contribute at all with have an opacity of 0 | |
| Jul 1, 2016 at 1:07 | comment | added | glwhart | g1 = DensityPlot... g1 /. Graphics[a_, b___] :> Graphics[{Opacity[0.1], a}, b] This didn't actually change the opacity of anything... BaseStyle -> Opacity[0.1] This helped---it did change the opacity of the colored patches but doesn't change the opacity of the mesh. (I forgot to include the fact that I have "MeshFunctions -> {#3 &, #3 &}, Mesh -> 10" included in my Options for Density plot, so it looks a lot like a ContourPlot.) | |

What is the intended application? Do you mean you want the output to have Head of Graphics, or be a graphics object of the kind that goes inside a Graphics?

Actually, even better: DensityPlot[x^2 - y^2, {x, -1, 1}, {y, -1, 1}, ColorFunction -> "SunsetColors", Frame -> False, BaseStyle -> Opacity[0.1]]

If the DensityPlot is called plot, then: plot /. Graphics[a_, b___] :> Graphics[{Opacity[0.1], a}, b].
