I created a 2D scatter plot with the vectors X, Y and Z and the following code
So that I would have X and Y plotted against one another, and Z would be represented as the graded colour of each marker. It worked fine, but I need a legend that shows the range of Z values represented by the range of marker colours. How do I make this?

x = [1:50]; % fake x data
y = [1:50]; % fake y data
z = [1:50]; % "intensity"
cb = colorbar; % creates the colorbar on side
% use caxis to change range on colorbar
caxis([10,30]); % low end is 10, high end is 30
