From: Makarand on 19 May 2010 06:45 I am using matlab 2010. I want to draw a colorbar on contourf plot but the contourf colors and colorbar colors are not matching The example code looks like this clear; clc;close all; X=1:10;Y=1:10; C=rand(10,10)*100; colormap(jet(7)); [c1 h1]=contourf(X,Y,C,fliplr([0 10 20 50 60 70 100])); clabel(c1,h1); colorbar I want to say if the values 20-50 fall in one category then why 20-30 30-40 is displayed on the colorbar please help in this problem
From: Makarand on 19 May 2010 07:39 I think no body could understand my problem I shall make it more brief please answer it. I modify the code like this clear; clc;close all; X=1:10;Y=1:10; C=rand(10,10)*100; colormap(jet(7)); [c1 h1]=contourf(X,Y,C,fliplr([0 10 20 50 60 70])); clabel(c1,h1); hold on pcolor(X,Y,C); colorbar See the Pcolr values are not matching with the matrix C why is so? any help please

Because you see we have 7 categories of contour and 7 colors, but some colors remain unused. and some have been used twice. so how to handle this problem. thanks again |
