Get the facecolor of a contourf plot

34 views (last 30 days)
I would like to find the facecolor of the the contourf patches. For example if :
[X,Y,Z] = peaks;
I would like to get the 5 different facecolors of the patches of the contour.
Thank you

[X,Y,Z] = peaks;
[l, h] = contourf(X,Y,Z,4)
hp = get(h,'children')
This gets you the value of the cdata. Look at the colormap to get the actual RGB color. Look at the colorbar to see what those values correspond to.

Kelly, is there some undocumented chance for some magic to set some FaceAlpha-Values for the plotted areas of the contourf-command?
