the image of the light curve cannot be seen in display windows probably due to the above error, I have latest matplotlib setup

This seems to be a very rare error, as even Google returns basically nothing. According to this comment on Stack Overflow, it may be caused by a problem with your matplotlib installation. How did you install it?

sameeresque commented 8 years ago

I had done the installation using apt-get ... sudo apt-get install python-matplotlib

vterron commented 8 years ago

Please try as told in the installation instructions. In your case:

sudo apt-get build-dep python-matplotlib python-scipy
sudo pip install "matplotlib>=1.2.1"
sameeresque commented 8 years ago

Did that but the same error, I had done the installation this way only not as I mentioned earlier

vterron commented 8 years ago

This seems to be a problem with the agg backend. Please try configuring your matplotlib installation to use a different backend via a matplotlibrc configuration file.
