Matlab直方图中不同范围的数据使用不同的颜色

Question

I would like to know is there any way that I can have different color for different range in the histogram so I say I want from 0 to 0.4 is blue and 0.4 to 0.8 red and 0.8 to 1 is green?

I know I can change the color of histogram bins and have two histogram with two different colors and all other things with bar commands like below :

[elements,centers]=hist('data1','#of bins');
bar(centers, elements,'FaceColor','r','EdgeColor','k');
hold on
[elements2,centers2]=hist('data2','#of bins');

But how to change the color within histogram?

Answer 1

The way to get data with different colors is to split the data into groups. In your case, split the data into three groups.

For example with three groups:

hist(data1);
hold on;
hist(data2);
hist(data3); 
h = findobj(gca,’Type’,’patch’);
display(h) 
set(h(1),’FaceColor’,’r’,’EdgeColor’,’k’);
set(h(2),’FaceColor’,’g’,’EdgeColor’,’k’);
set(h(3),’FaceColor’,’b’,’EdgeColor’,’k’);
