Define Interval in contourf
显示 更早的评论
Hi all,
I'd like to define the interval, in which contourf plots the lines. I've got data with x-y-z, where the z-values are within [0 1], but I'd like them to appear in levels between [0.5 1]. My attempt was the following:
[c,h] = contourf(meshX1/d_n,meshX2*2/d_n,meshZ,10); % interpolated
caxis([0.499, 1.001])
resulting in essentially the same line spacing, only the colours are adjusted to the defined interval (see picture).
Anyone having an idea? Thanks in advance!
Georg

See if this works:
v = linspace(0.5, 1, 10); % Define ‘10’ Intervals From ‘0.5’ To ‘1’
[c,h] = contourf(meshX1/d_n, meshX2*2/d_n, meshZ, v); % interpolated
caxis([0.499, 1.001])
Note — I do not have your data so this is UNTESTED CODE. It should work.

My pleasure.
I am guessing here. This adds two contours at the minimum and maximum of ‘meshZ’. I cannot test it, so you will have to test it to see if it works:
v = [min(meshZ(:)) linspace(0.5, 1, 10) max(meshZ(:))]; % Define ‘10’ Intervals From ‘0.5’ To ‘1’
