Re: [Matplotlib-users] legend not draggable when secondary y-axis present
For the legend to be picked by mouse, it must be placed in the top most axes. ax = subplot(111) l1, = ax.plot([1,3,2]) ax2 = ax.twinx() lab = ax2.legend([l1], [test]) I hope this clarifies your issue. If not, please post a simple but complete example that demonstrates your problem. Regards, -JJ On Wed, Jan 18, 2012 at 12:53 AM, German Salazar salger...@gmail.com wrote: Any ideas? Also, as in the example here, the legend seems to be behind the quantity being plotted against the one of the secondary y-axisdoes this have anything to do with that?...it is that maybe the legend is draggable but I am not getting to it? gsal -- Keep Your Developer Skills Current with LearnDevNow!

Re: [Matplotlib-users] Why pixel marker size is 4 pixels?
How are you plotting your points. If you use *plot*, there is a *markersize* parameter. If you use *scatter*, the third argument controls the marker size. But you may actually complaining about other issues, e.g., antialiasing, etc. So, if above are not your answer, please post a complete example and describe your problem in more detail.

Re: [Matplotlib-users] Why pixel marker size is 4 pixels?
Thanks JJ. The problem seems not to be a size issue -- markersize has no effect when use marker=, (pixel). I have also tried to turn off aa, and it doesn't help either. I also tried different backends. The PNG output from Agg and Cairo is slightly different: Agg's point has 4 solid pixel, while Cairo's has 4 pixel with random shade. Postscript output has the same problem. The pixel in an EPS file generated by mpl is significantly bigger than that from another drawing program I used. The problem occurs in all my plotting scripts, e.g., this basic one: [CODE] import numpy as np x=np.arange(100) y=np.random.randn(100) ioff() fig=gcf() fig.clf() ax=fig.add_axes(0.15,0.1,0.8, 0.85) ax.plot(x,y,k,) ion() fig.canvas.draw() [/CODE] Here is how I identify the problem: 1. use the above script to plot on screen 2. savefig(plot.png) 3. open plot.png in GIMP and check the pixel size. I also attached the two PNG files generated with Agg and Cairo backends. On Sun, Feb 5, 2012 at 6:45 AM, Jae-Joon Lee lee.j.j...@gmail.com wrote: How are you plotting your points.

[Matplotlib-users] axes.hist gets fooled by intermixed colors as strings and RGB
HI,
I have troubles getting to wirk a hitogram plot. I have colors in
RGB as tuples of 3 values and also some colors defined as string,
e.g. 'orange'. I get the folowing error:
File /usr/lib64/python2.7/site-packages/matplotlib/pyplot.py, line 2332, in
hist
ret = ax.hist(x, bins, range, normed, weights, cumulative, bottom,
histtype, align, orientation, rwidth, log, color, label, **kwargs)
File /usr/lib64/python2.7/site-packages/matplotlib/axes.py, line 7598, in
hist
raise ValueError(color kwarg must have one color per dataset)
ValueError: color kwarg must have one color per dataset
I think it is about the code in this patch:
http://permalink.gmane.org/gmane.comp.python.matplotlib.scm/4600
I hacked a bit the code in colors.py and axes.py to get more debug.
As you can see below it seems a previous value if left in the colors variable
from a previous iteration (I think).
['orange', (0.9468480101059871, 1.0, 0.0)] = colors[:2]
[cut]
pylab.hist(counts[:2], histtype='bar', align='mid', log=True,
bins=len(counts[:2]), color=colors[:2], label=adapternames[:2])
File /usr/lib64/python2.7/site-packages/matplotlib/pyplot.py, line 2332, in
hist
ret = ax.hist(x, bins, range, normed, weights, cumulative, bottom,
histtype, align, orientation, rwidth, log, color, label, **kwargs)
File /usr/lib64/python2.7/site-packages/matplotlib/axes.py, line 7598, in
hist
raise ValueError(color kwarg must have one color per dataset: color=%d,
nx=%d, color='%s', nx='%s' % (len(color), nx, str(color), str(nx)))
ValueError: color kwarg must have one color per dataset: color=2, nx=1,
color='[[ 1. 0.64705882 0. 1.]
[ 0.94684801 1. 0. 1.]]', nx='1'
Alternatively I would believe that matplotlib breaks because I have for
different
data points same color ('orange' appears maybe 10x in my colors list) but the
above slice [:2]
excludes this a the cause I am getting right now.
If it matters I generated the colors by this approach:
for _n in range(1,cnt1 + 1):
_h1 = sorted([uniform(0.15, 0.85) for x in range(_n)])
_HSV_tuples1 = [(_h1[x], 1.0, 1.0) for x in range(_n)]
_RGB_tuples1 = map(lambda x: colorsys.hsv_to_rgb(*x), _HSV_tuples1)
but these are mixed together with those defined as string (e.g. 'orange')
before they are sent to matplotlib.
Thank you for you help.
Martin
BTW: Would be nice if the default error messages on the above shown raise() were
more detailed.
