till if I do plot based on pyplot.pcolor, I have a nice and seems correct graph. So, actually, I am not sure what is the problem for showing the regular/linear plot. I hope I made it clear now.. Would it be possible to give me some hint please? Thank you in advance, Sue On Sun, Dec 18, 2011 a

Re: [Tutor] plotting in python

The output of the print len(Conc[0]), len(z) is 100 3600. Now I changed Conc[0] to Conc[1], and the output is: 100 100 But still I need to see from Concentration from 0. On Thu, Dec 1, 2011 at 5:26 AM, Asokan Pichai wrote: > On Thu, Dec 1, 2011 at 2:38 AM, stm atoc wrote: >> Hi there
