Re: [Matplotlib-users] key_press_events on macosx
I have python 3.3.2 from python.org installed as a Framework. I set up a
virtualenv to test the script
$ virtualenv-3.3 mpl121 --no-site-packages
$ .mpl121/bin/activate
$ pip-3.3 install numpy
$ pip-3.3 install matplotlib
With this setup, key events are passed to the window behind the active plot
window and no event is printed by the test script. Mouse clicks in the plot
window do cause the script to print out the event. I even tried installing
1.4.x into the virtualenv with
$ pip-3.3 install
git+https://github.com/matplotlib/matplotlib.git#egg=matplotlib
The key events were not printed out by the script.
I tried creating a different virtualenv using --system-site-packages and the
script failed to detect key events.
If I deactivate the virtualenvs and run the script with
matplotlib-1.4.x-py3.3-macosx-10.6-intel.egg in
/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/
the key events are printed by the script.
I'm not sure why using matplotlib from a virtualenv causes the key events to be
ignored in my setup. I should have stated in my first reply that I used a
virtualenv to test 1.2.1 and 1.3.0rc2 but not 1.4.x.

I've only tested against the prepackaged python 2.7, mpl 1.2.1 in an
anaconda install. Anaconda is not a framework build.

Re: [Matplotlib-users] key_press_events on macosx
The script works for me with matplotlib-1.2.1 both with Python2 and with
Python3 with the MacOSX backend.
To rule out the usual culprit, is your Python3 installed as a framework?

[Matplotlib-users] Graphics issues when combining matplotlib widgets: Spanselector, cursor, fill_between:
Hi, I have found minor graphical issues while using the spanselector, cursor
and fill_between widgets, which I would like to share with you.
All of them, can be experienced in this code (which I took from the
matplolib example)
"""
The SpanSelector is a mouse widget to select a xmin/xmax range and plot the
detail view of the selected region in the lower axes
"""
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import SpanSelector
import matplotlib.widgets as widgets
Fig = plt.figure(figsize=(8,6))
Fig.set_facecolor('w')
Fig.set
Ax = Fig.add_subplot(211)
x = np.arange(0.0, 5.0, 0.01)
y = np.sin(2*np.pi*x) + 0.5*np.random.randn(len(x))
Ax.plot(x, y, '-')
Ax.set_ylim(-2,2)
Ax.set_title('Press left mouse button and drag to test')
RegionIndices = []
ax2 = Fig.add_subplot(212)
line2, = ax2.plot(x, y, '-')
def onselect(xmin, xmax):
if len(RegionIndices) == 2:
Ax.fill_between(x[:], 0.0, y[:],facecolor='White',alpha=1)
del RegionIndices[:]
indmin, indmax = np.searchsorted(x, (xmin, xmax))
indmax = min(len(x)-1, indmax)
Ax.fill_between(x[indmin:indmax], 0.0,
y[indmin:indmax],facecolor='Blue',alpha=0.30)
thisx = x[indmin:indmax]
thisy = y[indmin:indmax]
line2.set_data(thisx, thisy)
ax2.set_xlim(thisx[0], thisx[-1])
ax2.set_ylim(thisy.min(), thisy.max())
Fig.canvas.draw()
RegionIndices.append(xmin)
RegionIndices.append(xmax)
# set useblit True on gtkagg for enhanced performance
span = SpanSelector(Ax, onselect, 'horizontal', useblit =
True,rectprops=dict(alpha=0.5, facecolor='purple') )
cursor = widgets.Cursor(Ax, color="red", linewidth = 1, useblit = True)
plt.show()
I wonder if there is some way to avoid these two small issues:
1) You can see that when you select a region the spanselector box (purple)
glitches. In this code the effect is barely noticeable but on plots with
many lines is quite annoying (I have tried all the trueblit combinations to
not effect)
2) In this code when you select a region, the area in the upper plot between
the line and the horizontal axis is filled in blue. When you select a new
region the old area is filled in white (to clear it) and the new one is
filled with blue again. However, when I do that the line plotted, as well
as, the horizontal axis, become thicker... Is there a way to clear such a
region (generated with fill_between) without this happening... Or is it
necessary to replot the graph? Initially, I am against doing this since I
have a well structured code and importing all the data again into the
spanselector method seems a bit messy... Which is the right way in python to
delete selected regions of a plot?
Any advice would be most welcome

[Matplotlib-users] key_press_events on macosx
Hi,
I'm working on a TextBox widget and have run into problems registering
key_press_events with the macosx backend. button_press_events work, but
key_press_events fail to trigger. If I change backends to tkAgg,
everything triggers as expected.
Can anyone reproduce this?
Run the following script; click the figure and bang on the keyboard. Mouse
clicks and keyboard clicks should echo on the screen. I'm using mpl 1.2.1
with Anaconda.
-matt
import pylab as plt
plt.switch_backend('macosx')
def print_event(event):
print 'event', event
ax = plt.subplot(111)
fig = ax.figure
x = range(10)
ax.plot(x, x)
# mouse clicks work on tkAgg & macosx
fig.canvas.mpl_connect('button_press_event', print_event)
# key presses only work on tkAgg
fig.canvas.mpl_connect('key_press_event', print_event)
plt.show()
