Hello,
I run the test.py example from the folder mplh5canvas/test. This example generated in the output folder 2 html pages (test.html and test_rendered.html) and also 2 images (filename.png and filename.svg). The test.html page is displayed ok, but when I open the test_rendered.html page the images from the column “H5 Canvas (PNG from Chrome 4.0 OSX)” are not displayed.
After I studied the source code of the test.py example I saw the following line:
(line 85) thtml += “
![]() ” % (“h5canvas_” + png_filename, w, h)
Now the question is: What is supposed to be “h5canvas_” + png_filename? There is no image generated with this name in the output folder.
The HTML 5 Canvas Backend was downloaded from here: http://code.google.com/p/mplh5canvas/downloads/list
Thanks!

Hey,
The test_rendered.html file probably should have been removed from the
release version. The idea behind this was to compare a PNG of the
browser rendered HTML5 plot with the standard PNG backend. (So users
without HTML5 support could see how the plugin performed).
These rendered PNG's are generated from the main test.html page by
running the rec.py receiver, and using the 'Connect' and 'Put images
to server' buttons on the bottom of test.html
Unfortunately the connect method uses a hardcoded IP address for the
WebSocket and so will need to be changed if you wanted to get this
working.
In short, as long as test.html produces three columns of plots (HTML5,
PNG and SVG), things are working fine.
I apologise for the slipshod release that left this code in 
Cheers,
Simon Ratcliffe
