 [Matplotlib-users] error bar and arrays (tuple way to solve a problem) From: Giorgio Luciano - 2006-12-05 08:14:29 Thanks to all for the replies :) I used a tuple to solve the problem because I dind't manage to reshape my array since it comes from a previous slicing, but not it seems to work. Is it the same problem because this doesn't work ? from pylab import * y=array([[ 1.02], [ 1.05], [ 1.03], [ 0.99], [ 0.97], [ 0.95], [ 1. ], [ 0.93], [ 1. ], [ 1. ], [ 0.98], [ 0.98], [ 0.94], [ 0.94], [ 0.96], [ 0.92], [ 1.01], [ 0.96], [ 0.99], [ 0.96], [ 1.03], [ 0.91], [ 0.99], [ 0.98], [ 1. ], [ 0.98], [ 0.96]]) pred=array([[ 1.02875 ], [ 1.03125 ], [ 1.02291667], [ 0.99541667], [ 0.96458333], [ 0.93625 ], [ 0.99375 ], [ 0.93708333], [ 1.00125 ], [ 1.01875 ], [ 0.98541667], [ 0.97291667], [ 0.94708333], [ 0.93458333], [ 0.96625 ], [ 0.92375 ], [ 1.005 ], [ 0.965 ], [ 0.98333333], [ 0.96666667], [ 1.02666667], [ 0.91333333], [ 1.005 ], [ 0.965 ], [ 0.98 ], [ 0.98 ], [ 0.98 ]]) figure(2) r=27 p2=plot(y,pred,'bo') t1=arange(1,r+1) for t1 in arange(1,r+1): text(y[t1-1], pred[t1-1], str(t1)) show() ###### End Plot 2 and gives this error ??Exception in Tkinter callback Traceback (most recent call last): File "C:\Python24\lib\lib-tk\Tkinter.py", line 1345, in __call__ return self.func(*args) File "C:\Python24\Lib\site-packages\matplotlib\backends\backend_tkagg.py", line 151, in resize self.show() File "C:\Python24\Lib\site-packages\matplotlib\backends\backend_tkagg.py", line 154, in draw FigureCanvasAgg.draw(self) File "C:\Python24\Lib\site-packages\matplotlib\backends\backend_agg.py", line 392, in draw self.figure.draw(renderer) File "C:\Python24\Lib\site-packages\matplotlib\figure.py", line 545, in draw for a in self.axes: a.draw(renderer) File "C:\Python24\Lib\site-packages\matplotlib\axes.py", line 1067, in draw a.draw(renderer) File "C:\Python24\Lib\site-packages\matplotlib\text.py", line 340, in draw bbox, info = self._get_layout(renderer) File "C:\Python24\Lib\site-packages\matplotlib\text.py", line 168, in _get_layout if self.cached.has_key(key): return self.cached[key] TypeError: unhashable type Thanks to all community :) Giorgio

 Re: [Matplotlib-users] error bar and arrays (tuple way to solve a problem) From: Eric Firing - 2006-12-05 08:26:07 Attachments: pytest.py Again, the problem with the sample you supply is that you are making 2-D arrays where what you need are 1-D arrays. Simply flattening y and pred before using them makes the script work fine, as attached. Or make them 1-D in the first place.
