[Matplotlib-users] easy question on ytick label format

[Mark B. <ma...@gm...>]

Hello List,

I want to plot plot([1000,2000])
Then on the y-axis, I want labels 1 and 2, and at the top of the y-axis I
want E3.
This works automatically with plot([1e7,2e7]).
But I assume that is something that can be set for plot([1e3,2e3]) as well.

I have been browsing the examples, and tried the (for me) obvious things,
but couldn't find the answer.

Any help is appreciated,

Mark

I think, you could just watch the video by John Hunter. He discusses 
these issues at length.

Thanks Zoltan.
That sounds like an interesting video that I will watch.

For now, does anybody know the answer?

You can set the (exponent) limits at which scientific notation is activated:

    plt.ticklabel_format(scilimits=(-3, 3))
