I have the following code to plot a structure with y-displacement as ColorMapData ('node.mat', 'elem.mat', 'phiOri.mat' are attached):
dis = reshape(phiOri(:, 1), [3, 3146]);
dis = dis';
scaleFactor = 1;
pdeplot3D(node, elem, 'ColorMapData', abs(dis(:, 2)));
The image is like this:
As you can see the majority of displacement are small, thus most of the structure are blue. Is there a way to enhance the contrast, i.e. enhance the display of region [0 0.06], such that change in the colormap are clearer?
I think change colorbar to log scale may achieve what I want, but I don't know how to do this, please help! Thanks in advance!
