Assign different colors to multiple plots without loop

16 views (last 30 days)
I have one array x and a multi-column array Y and would like to plot all Y#s on the same diagram against X and assign each plot a different color, coming from the color array named ColorSpec (e.g. ColorSpec=[0 0 0; 1 0 0, ...]). Although using a loop is always an option but since this will happen multiple times in the code I would like to avoid a loop for brevity. Is this possible?

Here is one way:
ColorSpec = [0 0 0;
1 0 0;
0 1 0;
0 0 1];
% Pretend data
x = sort(rand(3,1));
y = rand(3,4);
figure
ax = axes;
ax.ColorOrder = ColorSpec;
ax.NextPlot = 'add';
plot(x,y)

It is OK if ColorSpec has more rows than lines in the plot. The plot will just use the first rows as needed.
It is also OK if ColorSpec has fewer rows than lines in the plot. The plot will "recycle" colors from the beginning again.

Oh, I didn't know that. That's pretty cool, thanks again!
