Plots return only axes but no curves

Posted 11 years ago
Hello, i got a huge problem with the Plotfunctions in Mathematica 9. When i try to plot a defined function it shows just a coordinate system with a white background. When this happens i try to Evaluate[..] the function. A few times this works actually. I'm really frustrated about this issue and would be very happy for help!

Dear Steffen, please provide Mathematica code. Take a few minutes to learn how to make proper posts with this tutorial:

Instead of guessing, it will be easier if you make up a MWE for a case.

But here is one case where no plot shows:
f[t_] := Sin[t]*I;
Plot[f[t], {t, 0, 10}]
But now a plot shows:
f[t_] := Sin[t];
Plot[f[t], {t, 0, 10}]
So you see why.

The possibilites are endless as to why a plot might not display at some point. To get better help please provide a MWE.
