Hi, I experienced similar error under python 2.7.5 win32 after dirty-upgrading from mpl 1.2.1 to 1.3.1 (w/o first removing the old version). A clean install solved the problem. Cheers, Gregorio -- DreamFactory - Open Sou

[Matplotlib-users] numpy masked array plot - isolated single unmasked value is hidden

2013-07-17 Thread Gregorio Bastardo
Hi, The following example demonstrates the problem, value 5 could not be seen w/o marker: data = np.arange(10) mask = [0,0,0,1,1,0,1,0,0,0] x = np.ma.masked_array(data, mask) plot(x) plot(x, '+') In my datasets, isolated unmasked values are rare, but placing a marker to spot them makes the whole

Hi Sterling, Thanks for the hint, using "line._legmarker" attribute solved the problem. I see the reason behind, however I still consider this as an incorrect behaviour, since marker toggling works in case the line is originally added to the legend without marker (so legend line and marker do not

[Matplotlib-users] legend marker update problem

2013-05-16 Thread Gregorio Bastardo
Hi, I've recently come accross an issue when working on an interactive marker toggling callback. The problem is illustrated below: import matplotlib.pyplot as plt fig = plt.figure() ax = fig.add_subplot(111) line, = ax.plot(range(10), range(10)) # uncomment next line to reproduce bug # line.set_m
