setting scientific number notation on colorbar

found a solution after 2 hours ...

colorbar(ax=ax1, orientation='horizontal',format='%.3f')

now, I need to know how to set up limits for all the images which are
exactly the same limits.
So far I'm failing with the use of "boundaries"

....

Would be happy to know

Oz,

Some plotting functions like pcolor and imshow have keyword args for vmin/vmax where you can explicitly set the min and maximum values for the colorscale. There are some more complicated things you can do with the colormap that are more generic to all plotting functions as well, but I would see if using vmin and vmax does the trick for you.

Hi Thanks for the answer,

actually, I always use
show and plot, I have no clue how to use the functions you suggested …

I’ll look into it.

Do you have an idea where I can find a description of the keyword “format”

‘%.3f’ is nice, but still not scientific format…

is this like Fortran?

you can use

‘%.3e’

for scientific format.

hi andre,
thanks for your reply,

do you know where I can find more documentation about this ?

Thanks,

Hi Oz,

Sorry, I am not familiar with what you are trying to do with your plots. Everything I have learned is from trial and error, the gallery page

http://matplotlib.sourceforge.net/gallery.html

and the user manual

http://matplotlib.sourceforge.net/contents.html

Good luck,

Andre

I believe so (I am not too familiar with fortran, but the ideas are similar in many languages like C’s sprintf. You can do ‘%.3g’ to pretty print the float numbers (in a sense), and ‘%.3e’ to always do scientific notation.
