Force pyplot to show actual axis values

Question

I am using Python and Pyplot to produce a plot. The y axis of the plot is generated automatically, and works fine.

If the range is small however, the y axis will produce values such as:

and then at the top of the axis, will say:

+1.543e-1

I would prefer that it just explicitly shows the values:

Could someone tell me how to do this please?

Take a look at the [ticker api](http://matplotlib.org/api/ticker_api.html), and perhaps this [example](http://matplotlib.org/examples/pylab_examples/major_minor_demo1.html#pylab-examples-major-minor-demo1) — Chris Zeh, Oct 15 '13 at 15:05
there is a PR in the works to be able to set this as an rcparam, should be in 1.4. — tacaswell, Oct 15 '13 at 15:29

Nice @tcaswell. I also would like that offset feature `off` by default. — Chris Zeh, Oct 15 '13 at 16:01

Alright, I think I found the total solution:

Here is a quick plot that recreates your problem:

plot((0.15435,0.15440,0.15445,0.15450,0.15455,0.15460),(0.15435,0.15440,0.15445,0.15450,0.15455,0.15460))

The following code (similar to how it was as shown here) should adjust the ticker like you want:

y_formatter = matplotlib.ticker.ScalarFormatter(useOffset=False)
gca().yaxis.set_major_formatter(y_formatter)
