Hi,

I am having some trouble exporting my figures to a vectorised format to use in Adobe Illustrator. I am using plots where the color of the line is a gradient. These work well on the matlab figure, but don't look good in illustrator. Basically illustrator is splitting each segment of the line with a different colour into a separate layer. Does anybody have any suggestions what I can do?

Here is an example bit of code:

n = length(x);
              p = plot(x,y,'r', 'LineWidth',5); hold on;
              cd = [uint8(ColorFade)' uint8(255*linspace(0,1,n))'].'; %cd is a 4x100 uint8 matrix
              drawnow
              set(p.Edge, 'ColorBinding','interpolated', 'ColorData',cd)

Thanks

I hit that wall too. I finally had to resort to bitmap export of specific parts of the figure, as suggested below, although I hate it because it's non-editable. I recombine them with parts of an EPS/SVG export of the full figure to get a hybrid document with editable text.

Overall, graphical export is something Matlab does decently for simple graphics, but complex 3D graphics with gradients and transperencies are beyond their mastery.
