[matplotlib-devel] log transfer of axis in matplotlib

[Chao Y. <cha...@gm...>]

Dear all,

When making plots, you want an log transfer of axis, but there are data
whose value is zero, at this time matplotlib prompts "Cannot take log of
nonpositive value",
but in most cases maybe you just want to check if the log axis make the plot
more nice-looking. So is it possible just change the function to make it
accept zero value
when making log transfer and set the the zero value on the log-transfered
plot remain as zero? By this way we don't have to change the zero value in
the data to a very small
value just for realizing the axis log transfer?

My matplotlib version is 0.91.2, Maybe in the new versions this has already
been done?

much thanks,

Chao
