Hi,
I would like to do create a scatter3 plot where the color of the circles is assigned by it's corresponding z axis value. I have tried the following code
load inputmatfile.mat
figure;
cmp = linspace(min(z),max(z),numel(z));
scatter3(x,y,z, [], cmp,'filled'); colorbar;
view(-80,15)
xlabel('x axis'); ylabel('y axis'); zlabel('z axis')
grid on;grid minor
However, this assigns the limits of the colorbar by the z axis but determins the colour of the circles based on the y-axis, which is not what I want.
Is there anyway to force it to choose the colour of the circles based on the z-axis value
