Every time I run a plot line, a blank graph opens up and none of the data gets plotted, even though it appears on my partner's computer.

Can you paste the code you are using that shows the problem? Include your import statements.

[caj92]

I don't know how to do that

[monroews]

copy your code and paste it here

Your code is good. Could you try this. Instead of executing code line by line, do the following Place your cursor anywhere in the python code. Press alt, shift, enter. That should execute all of the code at once.

Thank you that works
