Suppose you have multiple measurement series with mean, max and min for each data point. fill3 (X,Y,Z,C) plots filled polygonal regions on 3-D axes as Patch objects with vertices at the ( x, y, z) locations specified by X, Y, and Z. Set the colors for the filled contour plot by changing the colormap. When attempting to change parameters like transparency and face colour, it can get confusing, so let's simplify. By changing property values, you can modify certain aspects of the patch. I2 = imfill (I) fills holes in the grayscale image I. You can check this by getting the Renderer of the current figure before and after plot setting the FaceAlpha. Assign the colormap to your axes, and then use the rows of the colormap to assign color to each patch. This emulator is open-source software and is being developed by Microsoft. fill3 returns a column vector of handles to patch objects, one handle per patch.
