Re: [Matplotlib-users] Modifying lasso_demo.py

[Scott H. <st...@co...>]

Thanks for the response. To be more specific, if I run the modified script in an ipython --pylab terminal:

In [1]: %run lasso_demo.py

In [2]:

The function returns, and the lasso manager is garbage collected as you say. In other words, the plot shows up, but I can't draw a lasso and select points. If I run the script in ipython without the pylab flag it works!

Why does enabling --pylab have this effect? Since I use pylab for day-to-day computing I'd like to incorporate some of these widgit tools in interactive sessions, but maybe that's not possible?  


Thanks, 
Scott
