Whiteout/Remove some part of the contour plot
69 views (last 30 days)
I use the built-in MATLAB function "scatterInterpolant" to plot a contour. The plot is shown below.
It's s stress contour and the ellipse is an empty space and there are no nodes inside the ellipse. I want the ellipse to be whiteout. Somehow I managed to set the values inside the ellipse to be zero (because I can't delete them) and I got the following result
I want the ellipse to be whiteout. Any sort of help is highly appreciated. Thanks in advance.
P.S. I use the fill command to fill the ellipse with white color but that's not a proper way to do it.

Hi Muhammad Usman,
instead of assigning Zero to the nodes you don't want to use, apply "nan"-Values. That will be treated as if there is no value assigned and will be plotted with white color.
x = -100:100;
y = -100:100;
inputData = rand(201);
inputData(abs(x)<=10,abs(y)<=10) = nan;
