Also can you please add a task to tasks.py to generate the documentation locally?

[prusse-martin]

I can add a task.
The build you linked is the official qmxgraph one, I am build the one from my fork here https://readthedocs.org/projects/prusse-qmxgraph-fork/builds/ the link in the initial description will point to the most recently build.

[prusse-martin]
