Re: [Matplotlib-users] align title of subplot with ylabel
Thanks for the suggestions, 'annotate' is what I need, I think.
I get errors though, also when I run the example scripts
from here:
http://matplotlib.sourceforge.net/trunk-docs/users/annotations_guide.html#using-complex-coordinate-with-annotation
.
I get the error 'NoneType' object is not iterable when I try plt.show()
or try to save to eps.
So I am not sure if I have the correct version of matplotlib installed.
I checked out the newest matplotlib from the svn repository, removed my
current installed version and installed the version in the 'trunk/'
directory. 'annotate' did not work.
Later, I installed matplotlib from the '/branches/v0_99_maint'
directory.
In both cases there were no errors in the installation, but still
'annotate' did not work.
Could it be that I have the wrong library from the svn repository
installed? Does r8319 mean release #8319?
Kind Regards
Hannes

Re: [Matplotlib-users] align title of subplot with ylabel
This can be done relatively easily with the current svn version of
matplotlib (r8319).
Below is the modified version of your code.
See
http://matplotlib.sourceforge.net/trunk-docs/users/annotations_guide.html#using-complex-coordinate-with-annotation
for how the annotation works.
While this is certainly possible with the released version, but it
will require you to write a few tens of lines of code. Basically, you
need create a custom Text class that update its position during the
drawing time.

###Code
import scipy
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(121)
plt.plot(scipy.sin(scipy.arange(1,100, 0.001)))
plt.xlabel('xlabel')
yl = plt.ylabel("ylabel")
plt.annotate("A", (0,1.), xycoords=(yl, "axes fraction"),
xytext=(0, 14), textcoords="offset points",
fontsize=14)
ax = fig.add_subplot(122)
plt.plot(scipy.cos(scipy.arange(1,100, 0.001)))
plt.xlabel('xlabel')
my_ticklabel = ax.get_yticklabels()[-2]
# Note that there is no guarantee that all ticklabels are drawn.
plt.annotate("B", (0,1.), xycoords=(my_ticklabel, "axes fraction"),
xytext=(0, 14), textcoords="offset points",
fontsize=14)

I haven't thought through the solution completely, but my intuition
says that this might be helpful:
http://matplotlib.sourceforge.net/examples/pylab_examples/anchored_artists.html
http://matplotlib.sourceforge.net/mpl_toolkits/axes_grid/users/overview.html#anchoredartists
These examples show ways of anchoring artists (like Text) to certain
locations. It's probably your best bet for getting what you want.

[Matplotlib-users] align title of subplot with ylabel
Dear all,
I'm struggling with the following problem plotting my data:
I have a figure with two panels next to each other, which I want to
label 'A' and 'B'. I want to left-justify my panel labels, but not to
the box that contains the plot, but to the y-axis label. I played around
with 'text()' and 'title()', but did not find a good solution except for
giving the coordinates manually to 'text()'. This would be very
inconvenient though, because I have many different plots on different
scales.
Here is what I tried:
###Code
import scipy
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(121)
plt.plot(scipy.sin(scipy.arange(1,100, 0.001)))
plt.xlabel('xlabel')
plt.ylabel("ylabel")
plt.text(0,1,"A", fontsize=14, transform=ax.transAxes)
ax = fig.add_subplot(122)
plt.plot(scipy.cos(scipy.arange(1,100, 0.001)))
plt.text(0,1,"B", fontsize=14, transform=ax.transAxes)
plt.xlabel('xlabel')
###End Code
So the texts 'A' and 'B' should be a little bit higher and more to the
left. The 'A' I want to align with the y-axis label of the left plot,
the 'B' with the values of the y-axis of the right plot.
I hope my question is clear, I will appreciate any help!
Thanks in advance,
Hannes
