Multi line color in graph
显示 更早的评论
Hi,
While trying to plot a graph
plot(1:10, rand(10,10))
Each line has a different color.
Is it possible to vary the color scale from a darker shade to lighter shade? For instance, from black to grey

Try this:
cmap = colormap(gray(10));
figure
hp = plot(1:10, rand(10));
set(gca,'ColorOrder',cmap)
Experiment to get dufferent results.

It works correctly for me in R2019b:
It plots only gray lines.

My pleasure.
My code should work in R2019a.

Unfortunately, I could only obtain this in 2019a

There was a change in r2019b about color order, such that it now affects lines already drawn. In previous versions you need to set the color order before you draw the lines.

@Walter — I didn’t realise that. Thank you!

I wish I could, since the code I posted works for me. The code appears to be correct, according to the ColorOrder property documentation. (The colororder function is new in R2019b.)
The set call should not be a problem, however the only thing I can think of at this point is to use a slightly different calling syntax:
cmap = colormap(gray(10));
figure
hp = plot(1:10, rand(10));
Ax = gca;
Ax.ColorOrder = cmap;
This also worked when I tried it.

Deepa, do you happen to be using MacOS Catalina ?
