I need to control aspect ratio of the plot as visible on the screen or 
printed.. for example, a plotted circle or ellipse must come out with 
the right aspect ratio. (Note: printing is primary, we assume printer 
pixels are perfectly square, and we don't care if the screen pixels are 
not quite square.)

(Note to John -- I'm in Ted Drain's group at JPL, and I'm looking at 
this early.. I know you've been hired to create an ellipse primitive.)

So what would be a way of controlling aspect ratio? Can this be done via 
pylab, or better done through the OO interface? I know that I can resize 
the figure canvas, but to be strictly correct I need to know the length 
of the axes in pixels, not the figure canvas.

Hi,

I'm sorry, but removing the texcache doesn't help. I have patched the 
matplotlib code successfully to solve this problem. I'll submit the 
patch at the sf.net site.

regards,

Hi,

I have tried matplotlib 0.87 and bumped on a problem with the dpi 
settings. I have set "text.usetex=True" and I use the Agg backend. When 
I write a figure to a png file at different resolutions, the size of the 
text in pixels remains the same, while it should be the size relative to 
the image size that is invariant.

I'll send a patch in the near future, unless someone else is already 
working on this.

regards,

Toon
