How can I create a scatterplot and map the outputs to a logarithmic colorscale?
显示 更早的评论
I want to create a scatterplot like the picture included, where the color of the output is mapped to a color on a logarithmic scale. I initially tried using a for loop with conditional statements and using the built in colors ('r','g','b','y', etc), but I want to have a larger variation of colors that change in intensity based on the output value of the point. Is this possible in MATLAB?

You can change the colorbar's scale to logarithmic with the following command:
set(gca,'ColorScale','log')
Here is it altogether with random values for y.
x = 1:1000;
y = 100000*rand(1,1000).*rand(1,1000).*rand(1,1000);
scatter(x,y,20,y,'filled')
ah=gca;
ah.YScale = 'log';
colorbar
set(gcf,'color','k')
set(gca,'color','k')
ah.XAxis.Color = 'w';
ah.YAxis.Color = 'w';
fh=gcf;
fh.Children(1).Color = 'w';
colormap(jet)
set(gca,'ColorScale','log')
