Simple plot fails with error “invalid command name ‘PyAggImagePhoto’”
I’m using python-3.2.2 with matplotlib 1.1.0 (from the py3 fork). I attempted a simple plotting test, and I get a blank Figure window together with the error messages below. I suspect that I haven’t got matplotlib and tk/tcl setup properly, but I’m not sure how to track down the issue.
TIA,
Eric
