[Matplotlib-users] Define minimum precision for tick labels

[André D. <and...@go...>]

Hi,

I have a minor style problem, but, nevertheless, I can't solve it with
googles help. I want to have a minimum precision displayed on my ticks, i.e.
if the ticks are -1,-0.5,0,0.5,1 it should be displayed this way instead of
-1.0,-0.5,0.0,0.5,1.0. With the tick formatter I can set the tick
precission, but only for the whole axis (if I set %d for the example, it
will be -1,0,0,0,1). Also I use MaxNLocator, so I don't predefine the ticks
(I thought it's more convinient to use this already done procedure instead
of writing my own), so I'm more flexible, for example when I zoom in, but
therefore I don't even know, which the maximum precision is.

Possible solutions would be:
1. There is a number precision definition (something like %x.xf) which
produces numbers with minimum precision (again -1.0000 becomes -1 and
2.47300 becomes 2.473)
2. Extract by MaxNLocator defined ticks, edit them accordingly and reassign
them (which would be still a lot of work)

I even checked for solutions in Latex (because I use Latex string coding),
but this is even more inflexible, when it comes to numbers. But maybe
someone knows anything.

Thanks!

Best regards,
André
