Maybe like this:
ax.annotate('Time = %f'%(MBH_inst[0],), size=18, xy=(3, 1), xycoords='data',
xytext=(0.8, 0.95), textcoords='axes fraction',
horizontalalignment='right', verticalalignment='top',
)
?
You can also adjust the number of shown digits right of the comma by setting
it up like this: %0.2f etc.
Just look it up in the python documentation (search hints: python string
format).
Wish you the best,
Malte

Re: [Matplotlib-users] Display the 'full' value on y axis
Hi, as you can see here (lotlib.sourceforge.net/api/ticker_api.html), you need to set your formatter to either ScalarFormatter and set it up, so no offset is used or FormatStrFormatter with something like %d.

Re: [Matplotlib-users] Formatting X-axis
Hi,
> Is there any API to draw the lines between the labels?
> I guess its not possible with this tool.
You could use the ticks' properties (one of their children is a
matplotlib.lines.Line2D instance which you could modify to your wishes). The
second possibility is see is you put a box with only two drawn borders around
the labels, which I think might lead to problems.
So if you want to inspect, what you can do with those ticks you can use
pyplot.getp(object_to_inspect) and pyplot.setp(object_to_inspect) aswell as
dir(object_to_inspect).
I mostly do this by having an open python shell where I create and check out
the properties I want to work on and a little script I modify to check out how
the changes affect the plot. What I did looked something like this:
>>> from matplotlib import pyplot
>>> fig = pyplot.figure()
>>> p = fig.add_subplot(111)
>>> p.yaxis.set_ticks([3,4,5])
[, , ]
>>> m = p.yaxis.set_ticks([3,4,5])
>>> dir(m[0])
['__class__', '__d..., 'get_children', 'get_cli...]
>>> pyplot.getp(m[0])
alpha = 1.0
...
children = [, >> m[0].get_children()
>>> pyplot.getp(m[0].get_children()[0])
>>> pyplot.setp(m[0].get_children()[0])
and if you don't have the return of creating the ticks ("m" in this case) then
you can get then using
>>> p.yaxis.get_children()
[, , ,
, , ,
]
Hope it helps,
Malte
