How to create and load a custom colormap?

55 次查看(过去 30 天)
I've got a plot which I want to create a colormap which will enable me to see the wrapped properties of the property I'm using (0=2pi).
I've tried using:
colormapeditor
Where I can set the colours I want, and then:
ax=gca
mymap=colormap(ax);
Which, for my specific map, gives me a colormap of:
mymap =

However, I can't seem to use it when I'm plotting using the following line:
subplot(3,3,9);imagesc(reconThresh);title('Text (A)'); colormap(gca, 'mymap');
Having tried to load it using:
load('mymap.mat');
Any help will be much appreciated, thank you!

It is not a good practice to put multiple statements on one line:
subplot(3,3,9);imagesc(reconThresh);title('Text (A)'); colormap(gca, 'mymap');
It is much clearer to give each statement its own line:
subplot(3,3,9);
imagesc(reconThresh);
title('Text (A)');
colormap(gca, 'mymap');

请先登录,再进行评论。

Assuming that mymap is a variable in the workspace:
colormap(gca,mymap);
