Plot/Graph

[Muhammad Ali]

Hi,

Could anybody tell me that how can I plot graphs by matplotlib and get expertise in a short time? I have to plot 2D plots just like origin software. 

Secondly, how could we draw some horizontal reference line at zero when the vertical scale is from -3 to 3? 

Looking for your posts, please.

Thank you.

p.s: Is there any short and to the point text book/manual/pdf to learn 2D plotting with matplotlib?
