Hello all,

I am new to this forum. I am using the R-Pi to produce some graphs.

I am using matplotlb and numpy (pre installed) on Occidentallis (basically raspbian)

However I have found it works when I startx and run the python code from within the GUI. But is there a way to run it without "startx"?

Current the end of the errors I get are:

Code: Select all
_tkinter. TclError: no display name and no $DISPLAY environment variable


note: that is not all of the errors but seems the most relevant.

Thanks for any help :D

You can use xvfb python script.py

I posted a more detailed answer with a graph here:

Hello

Thanks for this reply, it works but what if i wanted to run the graph in real time rather than saving it using the command show()?

Thanks for all the help!
