[Matplotlib-users] remove previous figure

[Chuang <chu...@gm...>]

Hi there,

I wanna plot two curves, and save to 2 different files. However, when I
used the following code, the 2nd file contains both the 2 curves.

plot(X1,Y1)
savefig('file1.png')
plot(X2,Y2)
savefig('file2.png')

It seems like the program memorize both of the two curves and save to
the 2nd file. How can I save only the 2nd curve in the 2nd file? 

Thanks,
CC
