Hi all,

below scatter plot has two variables plotted against each other and a third variable provides the color. For the third variables most values lie between 1 and 10 and only one value is at 30 (hence the colorbar range from 0-30).

Is there a way that I can shift the color range so I get more variations in color between 0 and 10?

Thanks in advance!

Although possible, perhaps it would be more appropriate to use a logscale instead of an awkwardly scaled colorbar.

在 MATLAB Online 中打开

Here's a colorbar for you to give you an idea of how you can build your own. The colorscale is not very intuitive.

part1 = jet(200);
part2 = [linspace(part1(end,1),0,200)',zeros(200,2)];
cmap=[part1;part2];
colormap(cmap)
scatter(rand(1,100),rand(1,100),[],rand(1,100))
colorbar

EDIT: slight improvement
