Thanks for the link! Although, it seems that legend does not support PolyCollection at all: "Remember that some pyplot commands return artist not supported by legend, e.g., fill_between() returns PolyCollection that is not supported." so that even trying to use a proxy artist results in an error (shown at bottom), with the code here: ------------------------------ listOfThingsPlotted = [] listOfLegendLabels = [] for column in sorted(yValues): temp = ax.fill_between(xValues, yValues[column], label=column) listOfThingsPlotted.append(temp) listOfLegendLabels.append(column) legend = plt.legend (listOfThingsPlotted,listOfLegendLabels,bbox_to_anchor=(1.25, 1), shadow=True, fancybox=True) ------------------------------ Error: ------------------------------ Traceback (most recent call last): File "/cms/cmsprod/bin/prodJobMonitorPlots_matplotlib.py", line 117, in <module> plotStackedJobsVsTime(inputFile, outputFile, outputTitle) File "/cms/cmsprod/bin/prodJobMonitorPlots_matplotlib.py", line 93, in plotStackedJobsVsTime legend = plt.legend (listOfThingsPlotted,listOfLegendLabels,bbox_to_anchor=(1.25, 1), shadow=True, fancybox=True) # Make legend File "/afs/hep.wisc.edu/cms/sw/python/x86/2.5.4/lib/python2.5/site- packages/matplotlib-0.99.1.1_r0-py2.5-linux-i686.egg/matplotlib/ pyplot.py", line 2437, in legend ret = gca().legend(*args, **kwargs) File "/afs/hep.wisc.edu/cms/sw/python/x86/2.5.4/lib/python2.5/site- packages/matplotlib-0.99.1.1_r0-py2.5-linux-i686.egg/matplotlib/ axes.py", line 4044, in legend self.legend_ = mlegend.Legend(self, handles, labels, **kwargs) File "/afs/hep.wisc.edu/cms/sw/python/x86/2.5.4/lib/python2.5/site- packages/matplotlib-0.99.1.1_r0-py2.5-linux-i686.egg/matplotlib/ legend.py", line 304, in __init__ self._init_legend_box(handles, labels) File "/afs/hep.wisc.edu/cms/sw/python/x86/2.5.4/lib/python2.5/site- packages/matplotlib-0.99.1.1_r0-py2.5-linux-i686.egg/matplotlib/ legend.py", line 582, in _init_legend_box handlebox.add_artist(handle) File "/afs/hep.wisc.edu/cms/sw/python/x86/2.5.4/lib/python2.5/site- packages/matplotlib-0.99.1.1_r0-py2.5-linux-i686.egg/matplotlib/ offsetbox.py", line 475, in add_artist a.set_transform(self.get_transform()) AttributeError: 'NoneType' object has no attribute 'set_transform' ------------------------------------------------------------------------------ Come build with us!
