matplotlib-devel Mailing List for matplotlib

This is much worse than I thought. The "inch" unit is used in many places in
matplotlib. In particular in `figure` and `savefig`. Please, please consider
allowing other units. Let me emphasise this once more: in Europe, and, I
believe in most places around the world, one NEVER uses inches. Neither in
engineering nor, i think, in typography. For most people "inch" is basically
an unusual measure of how big screens are. I'm not kidding. Same for dpi,
it's a specific measurement of a resolution but nobody thinks of it as a
number of pixels per inches.
I have nothing against an internal use of inches inside matplotlib but
please consider allowing other units for all kinds of interfaces with the
user!
The best choice in my opinion would be to have a unit preference in the
.matplotlibrc file. This unit could be, say, `inch` or `cm` (or mm). Then
any length would be expressed using this unit of length. That seems simple
enough, doesn't it?
How difficult would it be to implement this?
As I said before, I'm willing to help for this.
cheers,
