plotting output

[eggulbahar]

Hello, I have been using pyxspec for a while and I have been trying to run the example threads here too, however, whenever I try to plot outside of the the Matplotlib option I never get an output (see image attached). This is the case when running the PyXspecWalkthrough1.ipynb as well. Is there something I am missing?

This is a known problem with the svg plotting driver in Heasoft-6.34 (and earlier) when used with recent versions of Jupyter Notebook. We've made a fix that will be in the next release of Heasoft. But in the meantime if you have the Heasoft-6.34 source code distribution and would like to make a patch fix yourself in your local build, please follow these instructions:

1. Copy and paste the following into a file named "sgdriv.patch"

2. Copy your sgdriv.patch file into the directory heasoft-6.34/tcltk/pgplot/drivers

3. From that same directory, do:

   patch sgdriv.c sgdriv.patch

(This final step assumes you have already run your $HEADAS/headas-init.(c)sh script.
Otherwise you'll get an "hmake: Command not found." error.)

4. 'cd' up 1 level into the directory heasoft-6.34/tcltk/pgplot and run the following 2 commands:

   hmake
   hmake install
