Can I use colormap to set color of my cumulative area chart in area()?

If so, how should I use it?

I tried to put something like colormap(map) on some different places but they just didn't work.

@稚萌 王, all questions should include what you have done so far so that we have some idea of what the question is. Attach code (.m) and data files (.txt, .csv, .mat etc) or at least the portion of code in a "Insert a line of code" box and error message like:

%code example
this = ~does %work
Unrecognized function or variable 'does'.

A simple example of my question is like follows:

a=[1,2,3,4,5]';
b=2*a;  % 2,4,6,8,10
c=3*a;  % 3,6,9,12,15

x_axis=1:size(a,1);
area(x_axis,[a,b,c],0);
colormap("summer");
legend('a','b','c');

The color of the figure I got is not "summer" in the colormap but more like something default in the command area().

How should I edit the codes to make the colormap command work? Thanks!

area dioesn''t use the figure's colormap directly, but it does use the axes' ''ColorOrder' by default, so maybe something like this is what you want to do:

a = [1;2;3;4;5];
b = 2*a;
c = 3*a;

data = [a,b,c];

x_axis = 1:size(a,1);

area(x_axis,data,0);

set(gca(),'ColorOrder',summer(size(data,2)));

legend('a','b','c')
