Hi all,
sorry, only reporting, no bugfix. I just discovered that an empty plot
with drawstyle 'steps', 'steps-pre', 'steps-mid' and 'steps-post' fails.
I am using matplotlib 0.98.5.2.
Example
plot([], [], drawstyle = 'steps')
...
C:\Python25\lib\site-packages\matplotlib\lines.pyc in
_draw_st
I found that in scatter plots the alpha values given by individual
entries in the color list are ignored. Here an example that shows
different combinations of color and alpha arguments:
x = [1,2,3]
y = array([1,1,1])
c = [[1,0,0, 0.0],
[1,0,0, 0.5],
[1,0,0, 1.0]]
scatter(x, y, s = 200

I attached a patch that emits a enter_notify_event if the mouse enters the
figure. Now the example behaves correctly.

Dear developers,
the following example shows a somewhat unexpected behaviour of the
get_xlim() method of an axis object: it returns a view to the internal
data structure used to store the data limits. Because of this saving and
restoring the data limits failed in this example (I am using matplo
Dear developers,
in matplotlib 0.98.3 I discoverd that in scatter individual alpha
settings (by giving a list of rgba values) are ignered. Here an example
that show this behaviour: All points show the same alpha value as given
by the alpha keyword argument. (Omitting it equals to the setting al

I also attached a simple test script (test_imshow.py) to show the
difference between image display with and without resampling. To see the
difference it might be necessary t

Dear developers,
I discovered that in backend_wx.py in _onPaint(), the callback function
