hey, i have many lines in X and Y axes, need to color each line according to a variable Z, how to do that ?
x
y
already plotted all the lines needed but need to add the color for each line according to the value of Z. for example if Z= 0 the line will take a color and if it;s 0.8 it takes another color( i mean how to add a colorbar for this )
thanks

You can modify the following code for your purposes.
where n will = the size of averageV
y(1:241,1) = 1:241
n = size(y, 1);
colors = hsv(n);
h = line([0 10], [y(1:241,1) y(1:241,1)])
set(h, {'color'}, num2cell(colors, 2));

Hello Michel,
I think you can use RGB colors so if you have the data in rows in X and Y it would be somethink like:
figure hold on for i = 1:size(X,1) plot(X(i,:),Y(i,:),'color',[Z(i) 0 1]) % There is needed that Z has a value from 0 to 1 for each row end
Hope it helps!
