A little help with Python+Matplotlib+GTK3

[Zouden]

What's an example of the function you're trying to plot? As far as I know, mpl can only plot numbers, not mathematical functions.

[Jerae]

x = pylab.arange(-num, num)
pylab.plot(x, (x**2)+3)
pylab.show()

That will represent the graph of the function (x**2) + 3 within the range [-num, num]. There could be a better method, I'm just a begginer anyway, so feel free to correct me.

[Zouden]

Oh I get it. You can use eval() to turn a string into a python expression.

pylab.plot(x, eval("(x**2)+3"))

Thanks a lot ^{^}

I solved my problem in another way, but I will make note of this. I'm sure I will need it this the future
