[Matplotlib-users] figlegend and title

[Werner F. B. <wer...@fr...>]

Hi,

I am just getting my feet wet with matplotlib.

I like plots with the legend outside the plotting area.  I found the 
demo which uses figlegend (thanks Andrea), this fits the bill - at least 
I think so.

However I can't get this to work within the wxcursor_demo.py, is 
figlegend only available with "from pylab import *"?

The other question is can I have sub-title lines, I saw that I can pass 
newline with title string but this uses the same font attributes, I 
would like a slightly smaller font and non bold etc for the second title 
line.

Looked through the archive on gmane, but couldn't find anything.

Appreciate any pointers on this.

See you
Werner

I'm not sure about that one, but there are a number of convenience 
functions that are only in pylab. If so, you have two choices:

1) Use:
import pylab
pylab.figlegend(...)

2) you can look at the code in pylab.figlegend, and see what it does, 
and make your own version.

By the way, I'm on  a quest to make the OO interface to matplotlib fully 
functional and convenient. If you want to work on it, John would 
probably except a patch to make a figure.legend() method.

pylab.figlegend is a thin wrapper to matplotlib.Figure.legend; see
http://matplotlib.sf.net/matplotlib.figure.html#Figure-legend

Got it, also don't understand why I could not get this to work yesterday 
- probably had crossed eyes.

Thanks and best regards

I still have a bit of a problem.

This puts the legend "more or less" outside the plot.  If I use "upper 
right" with only two lines it is o.k., however if I use e.g. "center 
right" then about half of the legend is still over the top of the plot.

Also if I have more then 2 lines I start overlapping even when using 
"upper right".

This is what I use (within the wxcursor_demo.py).
self.figure.legend((pLine, cLine), ('Purchase', 'Consumption'), 'upper 
right')

I would like the legend being totally outside the plot, I am o.k. with 
that the overall canvas would have to be a bit larger.

Is there a way I can do this?  BTW, I tried using "axespad = 0.02" with 
different values, i.e. "-0.15" puts it to the right, but half the legend 
isn't visable anymore.

Thanks and best regards
Werner

I think the best approach is to use fig.add_axes rather than
fig.add_subplot to create your axes.  Then you can make it the exact
size you want.  You can also place the figure legend anywhere you want
by using loc=(x,y) instead of a location string.  I just noticed this
was undocumented :-(.  It *is* documented for the axes legend, and
I'll fix the figure legend docstring for the next release.

Here's a little example

    import pylab as p
    fig = p.figure()
    ax = fig.add_axes([0.1, 0.3, 0.4, 0.4])

    lines = ax.plot([1,2,3])
    fig.legend(lines, ('hi', ), loc=(0.6, 0.6))
    p.show()

Hope this helps,
JDH

Pitty that I can't have both.  But I'll worry about this one when I 
actually do make use of the subplots.

You think I would have found it:)

[Matplotlib-users] sub-title

[Werner F. B. <wer...@fr...>]

The part about the sub-title got over looked, so I'll post again - 
anyhow it was bad from me to stick two things into one message - sorry!

Is it possible to have sub-title lines, I saw that I can pass newline 
with title string but this uses the same font attributes, I would like a 
slightly smaller font and non bold etc for the second title line.

Thanks for any hints.
Werner

[Matplotlib-users] Re: sub-title

[Werner F. B. <wer...@fr...>]

Hi All,

I figured this out, just doing something along these lines does the 
trick for me.

         self.figure.text(0.5, 0.95, title,
                horizontalalignment='center')
         self.figure.text(0.5, 0.92, 'sub title',
                horizontalalignment='center')


See you
Werner
