Why is my scatter plot blank?
显示 更早的评论
Hello,
I am running a script in my computer where any scatter plot turns up empty. I have run the same script in another computer where it had no problem so there is no error in the cod to cause this.
Does anyone have any idea what might be wrong? I am using Matlab 2017a.
Thank you!

There is no chance to guess the reason. Please provide more details, e.g. a piece of code which reproduces the problem.
You might have redefined a function. If you have e.g. a user-defined file called "scatter.m" in your Matlab path, which does nothing, the different behavior would be explained.

Have you try setting a breakpoint on any of the scatter call and seeing what values it is given?
Does a very basic scatter produces a plot on your machine, e.g.
scatter([1 2], [1 2])

Does this work by any chance?
scatter([1 2 3], [1 2 3]);
set(gcf, 'renderer', 'painters')

scatter([1 2 3], [1 2 3]);
set(gcf, 'renderer', 'painters')
Sometimes there's a bug that prevents the graphics card from properly drawing the figures generate by Matlab via the OpenGL renderer (default). It's been an on and off bug for a while:
You could use this to set the default renderer for all figures generated:
set(0, 'DefaultFigureRenderer', 'painters')
