Why does exporting a SCATTER figure using the PRINT command with the '-dill' flag not work in MATLAB 7.0 (R14)?

When exporting a figure to Adobe Illustrator format created using the SCATTER function, MATLAB returns errors and does not create the file, or creates it incompletely.

Reproduction steps:

X=[.25 .75];

Y=[.25 .75];

C=[1 0 0; 0 0 1];

scatterHandle=scatter(X,Y,25,C);

print -dill myScatter

I get the following error:

 ??? Error using ==> print

 Error using ==> print

 Error using ==> graphics\private\render

 Error using ==> hardcopy

Adobe Illustrator driver does not print in Z-Buffer or OpengGL mode.

If the attempt is made to set to the 'painters' renderer using:

set(gcf, 'renderer', 'painters')

The following warning is returned and the circles no longer appear on the SCATTER plot:

 Warning: RGB color data not yet supported in Painter's mode.

This is an issue with the way the patches store CData. The following makes a direct colormapping for each of the markers so that now Painters should be able to render the plot correctly:

X=[.25 .75];

Y=[.25 .75];

C=[1 0 0; 0 0 1];

colormap(C)

scatterHandle=scatter(X,Y,25,1:size(C,1));

print -dill myScatter.ai %where myScatter.ai is the filename being created
