I am trying to do a stem plot with all the lines the same color. When I plot any of the examples from the website, all the lines have a gradient color on them, which makes my dataset confusing. I am using 2016a.

I have tried to change the color parameter of the data, but all this changes is the marker color. Please can someone direct me in the right direction as to how I can change this? I have included a picture of what my output looks like:

Ok thank you :), And do you think it is possible to plot in 3D using stem3 X, Y and Z and have a color gradient in Z axis ?

Yeah, it's probably possible. Not with stem3, but with patch or surface.

It may be perception rather than reality. Experimentally, increase the line width, and the lines look as they should:

figure(1)
stem(X1,Y1,'Marker','none','Color',[0 0.498039215803146 0], 'LineWidth',2);
hold on
stem(X1(Y1>30),Y1(Y1>30),'Marker','none','Color',[1 0 0], 'LineWidth',2);
hold off

Thank you, this seems like an annoying feature, but yes increasing the line width helps.

My pleasure.

I didn’t see any problem with your code, so this was my first troubleshooting step.

That looks like the graphics driver bug which was discussed in this thread. Do you have an Intel GPU and Windows 10? My understanding is that the bug is limited to a particular Windows 10 driver version from Intel.

If that's the case, that thread has a couple of workarounds.
