Hi All,

I have installed matplotlib-py25  on both my Desktop (intel mac) and  
Macbook pro (intel) both running Leopard.
During testing I found that everything worked fine on my Macbook, that  
is I could do a simple plot, however following the same fink install  
process on my Desktop
I was unable to do the same simply plot. It seems as though it is not  
recognizing the plot command.

The simple plot I'm doing is;

from  pylab import *
plot([1,2,3,4])
show()

I inputted this line by line and got an error when I inputted the  
second line and the error was;

 >>> plot([1,2,3,4])
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
   File "/sw/lib/python2.5/site-packages/matplotlib/pylab.py", line  
2023, in plot
     b = ishold()
   File "/sw/lib/python2.5/site-packages/matplotlib/pylab.py", line  
937, in ishold
     return gca().ishold()
   File "/sw/lib/python2.5/site-packages/matplotlib/pylab.py", line  
883, in gca
     ax =  gcf().gca(**kwargs)
   File "/sw/lib/python2.5/site-packages/matplotlib/pylab.py", line  
893, in gcf
     return figure()
   File "/sw/lib/python2.5/site-packages/matplotlib/pylab.py", line  
859, in figure
     figManager = new_figure_manager(num, figsize=figsize, dpi=dpi,  
facecolor=facecolor, edgecolor=edgecolor, frameon=frameon,  
FigureClass=FigureClass, **kwargs)
   File "/sw/lib/python2.5/site-packages/matplotlib/backends/ 
backend_tkagg.py", line 88, in new_figure_manager
     window = Tk.Tk()
   File "/sw/lib/python2.5/lib-tk/Tkinter.py", line 1636, in __init__
     self.tk = _tkinter.create(screenName, baseName, className,  
interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: couldn't connect to display "localhost:0.0"

Could anyone please help me with this, as I can't seem to figure out  
why I'm having no problems on my Macbook but having problems on the  
Desktop. The only think I can think of is that the Pylab.py file was  
become corrupted during installation, although it seems fine to me.

Cheers

Al
