I am trying now but am stuck on: How can I plot the data given that, from the database, each datapoint is of the form ''0:00:02.994000'? Is there a way to tell matplotlib to read that as a time duration?

[Matplotlib-users] handling pick events doesn't work for me
Hi
I have a GTK application with the code
def on_pick(event):
print "on_pick"
thisline = event.artist
xdata, ydata = thisline.get_data()
ind = event.ind
print 'on pick line:', zip(xdata[ind], ydata[ind])
cid = fig.canvas.mpl_connect('pick_event', on_pick)
but the routine never gets called when I click the left mouse button.
Instead, the FigureCanvas "pick" method is called.
What am I doing wrong??

I am able to confirm that the problem occurs with v1.0.1, however, it appears that it is solved in the current development trunk and will work properly in the upcoming v1.1.0 release. I am not 100% certain which change it was that fixes this, but it is likely due to my work to make mplot3d functions accept empty inputs. This change would have likely allowed mplot3d to skip some operations under certain conditions. Because of the significant work that has gone into mplot3d since the v1.0.0 release, I would recommend all mplot3d users to upgrade to v1.1 when it is released. I hope this helps!

[Matplotlib-users] Failure to plot almost flat surface with matplotlib 1.0.1 on both Windows and Linux (bugreport)
Hello, We've encountered a problem plotting a nearly flat surface. Interestingly exactly flat surface can be plotted just fine, so it seems the bug is triggered when a range of values on z axis is very narrow. The problem can be easily reproduced on 32-bit windows and 64-bit linux, the only platforms I have handy, so most likely it is not platform specific. Both platforms have Python 2.6 and Matplotlb 1.0.1, and I've also seen the same error on Windows with Matplotlib 1.0.0. Here is a simplified repro: -- from matplotlib import pyplot from mpl_toolkits.mplot3d import axes3d import numpy n = 3 m = 4 x = range(n) y = range(m) z = [ 0.2 for i in range(n*m) ] z[1] = 0.3 # comment this line to make it pass figure = pyplot.figure( 0 ) ax = axes3d.Axes3D( figure ) x = numpy.array( [ [ t ] * m for t in x ] ) y = numpy.array( [ y ] * n ) z = numpy.array( z ) z = z.reshape( [ n, m ] ) wire = ax.plot_wireframe( x, y, z ) figure.show() pyplot.draw() - Here is a traceback: Traceback (most recent call last): File "C:\plotbug.py", line 21, in pyplot.draw() File "C:\Python26\lib\site-packages\matplotlib\pyplot.py", line 358, in draw get_current_fig_manager().canvas.draw() File "C:\Python26\lib\site-packages\matplotlib\backends\backend_tkagg.py", line 248, in draw FigureCanvasAgg.draw(self) File "C:\Python26\lib\site-packages\matplotlib\backends\backend_agg.py", line 394, in draw self.figure.draw(self.renderer) File "C:\Python26\lib\site-packages\matplotlib\artist.py", line 55, in draw_wrapper draw(artist, renderer, *args, **kwargs) File "C:\Python26\lib\site-packages\matplotlib\figure.py", line 798, in draw func(*args) File "C:\Python26\lib\site-packages\mpl_toolkits\mplot3d\axes3d.py", line 172, in draw ax.draw(renderer) File "C:\Python26\lib\site-packages\mpl_toolkits\mplot3d\axis3d.py", line 243, in draw newval = get_flip_min_max(xyz1[0], newindex, mins, maxs) IndexError: list index out of range If you comment out "z[1] = 0.3" line, and therefore make surface perfectly flat, then it will plot just fine.
