Re: [Matplotlib-users] Image plotting using the OO interface
David Goldsmith [EMAIL PROTECTED] 06/19/08 9:39 AM
Hi! I'm having trouble figuring out how to plot an array as an image with the
OO interface - please help (e.g., w/ an example). Thanks,
DG
From the examples
http://matplotlib.sourceforge.net/matplotlib_examples_0.98.0.zip
../examples/api/agg_oo.py
#!/usr/bin/env python
A pure OO (look Ma, no pylab!) example using the agg backend
from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
from matplotlib.figure import Figure
fig = Figure()
canvas = FigureCanvas(fig)
ax = fig.add_subplot(111)
ax.plot([1,2,3])
ax.set_title('hi mom')
ax.grid(True)
ax.set_xlabel('time')
ax.set_ylabel('volts')
canvas.print_figure('test')
You can replace the call to ax.plot() with a call to ax.imshow() or ax.pcolor()
Hope that gets you going.
Cheers,
Scott

Re: [Matplotlib-users] Image plotting using the OO interface
On Thu, 19 Jun 2008, Scott Sinclair apparently wrote: canvas = FigureCanvas(fig) What is the relationship between a figure and a canvas? My impression is the following. You can do all your drawing on a figure. When you want to render the figure (e.g., to screen, or printing to file), and not until then, you need a canvas. A canvas will therefore always be associated with a particular backend. But when one creates a figure canvas, the canvas registers itself with the figure. What does the figure get out of this? (E.g., if we want the figure to draw itself to the canvas, the canvas could always pass itself to the figure. Right?) Thank you, Alan Isaac - Check out the new SourceForge.net Marketplace.

Re: [Matplotlib-users] Large axis labels/positioning the axes

One more related thing: is there any way to retrieve the size of a textbox

ax.get_ymajorticklabels[0].get_width()?
This is not very easy since the renderer is not known until the figure
is drawn. After the window is drawn and the text instance knows its
renderer, you can call t.get_window_extent(). So you would likely
want to connect to the on_draw method and get the window extent
there, and then do something with it, eg move the left of the canvas
over. Here is a recursive, iterative solution that will gradually
move the left of the subplot over until the label fits w/o going
outside the figure border (requires 0.98)::
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
ax.set_yticks((2,5,7))
labels = ax.set_yticklabels(('really, really, really', 'long', 'labels'))
def on_draw(event):
for label in labels:
bbox = label.get_window_extent()
if bbox.xmin0:
print 'adjusting left of subplot'
fig.subplots_adjust(left=1.1*fig.subplotpars.left)
fig.canvas.draw()
break
fig.canvas.mpl_connect('draw_event', on_draw)
plt.show()
Also, I'm kind of wondering why things like set_text() on that doesn't work.
In general I haven't had much success with editing the properties of objects
like this.
The tick labels are a bit special, since they are generated on the fly
(eg if you are panning and zooming, new ticks must be created and sold
ones destroyed). So you can't set their text directly, but rather
need to create a tick locator and a tick formatter as described in

The Figure is the top level matplotlib artist container that contains all the other matplotlib.artist.Artist instances (Axes, Line2D, etc..). Artists don't know anything about output formats (GDK, PS, SVG) but they do know about renderers (matplotlib.backend_bases.RendererBase) which have methods like draw_line, draw_rectangle, and draw_text. The renderer subclasses know the various output languages like postscript or svg. The canvas is the target of the drawing by the renderer, and the canvas puts all the pieces together. The canvas contains a renderer that knows how to draw on the canvas, and it also contains the figure instance to be drawn. The canvas calls fig.draw(renderer) and then the figure instance in turn calls self.figurePatch.draw(renderer) and then the figurePatch, a matplotlib.patches.Rectangle instance, calls renderer.draw_rectangle(graphicscontext, 25, 40) So the renderer doesn't know anything about the matplotlib artist Rectangle, but the Rectangle knows how to tell the renderer to draw itself. This design decouples the functionality to make it possible to change the artists w/o affecting the renderers, so the drawing API is not affected by the matplotlib artist classes.

[Matplotlib-users] threading problems
I need to have a plot window hang around and be occasionally updated by
my script as it does things. I've been looking through examples and have
not been able to get anything to work.
My current approach, inspired by strip_chart_demo.py and others in the
animation examples, is:
import gobject, matplotlib, sys
matplotlib.use('GTKAgg')
import matplotlib.pylab as pylab
import threading, time, random
class PylabThread(threading.Thread):
def __init__(self):
threading.Thread.__init__(self)
def update(self):
pylab.draw()
def run(self):
gobject.idle_add(self.update)
pylab.plot([random.random() for i in xrange(1000)])
pylab.show()
if __name__ == __main__:
p = PylabThread()
p.start()
i = 0
while True:
print i
i += 1
time.sleep(.5)
Running this, however, yields the odd behavior that you only get numbers
printed every half second (as you should) if you move the mouse (or hit
keys, or otherwise generate events) within the plot window!
What's going on, and how can I fix this?
Thanks!

If I have a function that gets a line, I can do line.axes.figure.canvas and walk backwards up the containment hierarchy to get what I need. This is backwards because a canvas holds a figure which holds an axes which holds a line, but everybody stores a reference to their parent. A side effect of having so many cyclic references is that we cannot use __del__ anywhere in the mpl class hierarchy since this breaks garbage collection with cyclic references. - Check out the new SourceForge.net Marketplace.

[Matplotlib-users] Global font size
Matplot folks, Is there a way to increase all font sizes globally across the board? I played around with some RC parameters but they don't seem to have any effect. I found that I could more or less achieve the desired result by the following steps: 1) plot to something like subplot(6,6,1). That is, make a 6x6 plot grid but only use the upper left subplot of it. With that the text is large relative to the plot, but spacing is not good, so... 2) Make plot window really large so text isn't overlapping so much 3) Save result to svg 4) in Inkscape or other svg editor cut out the big unused region, and fix badly positioned labels (e.g. text too far left in legend box). That basically worked, but it's quite hacky. I think it's pretty obvious why this would be useful, but if not, my particular use case is that I want to make some graphs that will be very small in the final document, so the text needs to be at about 9pt in an overall bounding box of approx. 3cm x 2cm.

#font.size : 12.0
You set that size, and then set a relative size (like medium) for your other
settings. I should include this in the new docs, if it is not covered
already.
According to the docs the rc function is supposed to be able to do the
same thing as editing matplotlibrc.
I tried doing
rc('font', size=20)
and several variations of that invoked at several different places in
my file, and it seemed to have no effect.
Did I do it wrong? Does rc() not really work as advertised?
Something completely different?
For what it's worth my matplotlib.pylab.__version__ is '1.1.0'

[Matplotlib-users] tick_left() and tick_right() with minor tick marks
Hi I have a plot that has two different y-axis scales and I want appropriate tick marks for the different y-axes. ie I want the tick marks on the left axis to correspond to the scale on the left axis etc... As far as I can tell the way to accomplish this, after consulting the documentation, is to use the tick_left() and tick_right() methods, I therefore have the following code: axes1.yaxis.tick_left() axes1.yaxis.set_major_locator(pylab.MultipleLocator(0.1)) axes1.yaxis.set_minor_locator(pylab.MultipleLocator(0.05)) axes2.yaxis.tick_right() axes2.yaxis.set_major_locator(pylab.MultipleLocator(5)) axes2.yaxis.set_minor_locator(pylab.MultipleLocator(1)) but the minor ticks are on both the left and right y-axes. How can I make the minor ticks for axes1 only appear on the the left and the minor ticks for axes2 appear on the right? Cheers Adam - Check out the new SourceForge.net Marketplace.

Matplot folks,
Is there a way to increase all font sizes globally across the board?
I played around with some RC parameters but they don't seem to have
any effect.
Here's a note from the default matplotlibrc:

I think in this case, you need to change those settings before importing
pylab:
import matplotlib
matplotlib.rcParams['font.size'] = 12
import pylab
or better yet, do it with a matplotlibrc file
For what it's worth my matplotlib.pylab.__version__ is '1.1.0'
Really? That looks like numpy's version, not matplotlib's.

pylab:

matplotlib.rcParams['font.size'] = 12
import pylab
I see. I usually just do it in one shot like:
from matplotlib import pylab as plot
or better yet, do it with a matplotlibrc file
For what it's worth my matplotlib.pylab.__version__ is '1.1.0'
Really? That looks like numpy's version, not matplotlib's.
I guess it's just namespace weirdness then. Using the import
incantation I gave above, plot.__version__ reports 1.1.0.
matplotlib.__version__ gives '0.98.0'.
I tried putting this in my matplotlibrc but it seems to have no effect:
font.size : 30.0
Just to make sure things were actually working I also tried this:
font.weight : bold
That one worked, all text on the plot turned bold. That suggests to
me that the global font size setting probably just has a bug at the
moment.
