Changing color of the Matlab plot at different ranges

Hi,

I want to have the below graph in two colors, the y-values > 600 should be red.

Right now I have a basic plot command.

I have read the litreature on this issue on the forums and previously asked questions - but none of them related to my problem

Try this:

indexes = yValues > 600;
plot(x(~indexes), y(~indexes), 'b.', 'MarkerSize', 10); % Plot in blue first.
hold on;
plot(x(indexes), y(indexes), 'r.', 'MarkerSize', 10); % Plot in red next.
