Did you try to install pydot?

sudo apt-get install python-pydot

Hi,

Thanks, after installing pydot, the flowgraph is working fine. A warning
though, but I think that can be ignored?

WARN: asynchronous message buffer overflowing, dropping message

There is one thing more. I clicked somewhere in the graph view of
performance monitor and following error came, I tried to replicate it
but I
was not successful.

Right, that’s just a warning.

I’ve worked on this problem, but it only affected me on the Runtime or
Buffer graphs, not the main canvas. I think something changed in the
plotting tools since we last had this running. But I can no longer
replicate the problem, so hopefully it’s rare and we can nail down the
problem later.
