Suppose I have:
x = ['1.34511','0.0234','-0.0890']
y = ['0.0987', '0.8763', '-0.0762']
How can I plot those values in matplotlib? I've already made a search about 'ticks', but I still don't understand...

edit:
My matplotlib 1.2 can plot the string lists fine btw, there is no need for conversion to begin with, just plot them as they are.
You can first convert them to a float32 Numpy array:
x = ['1.34511','0.0234','-0.0890']
y = ['0.0987', '0.8763', '-0.0762']
x = np.array(x, dtype=np.float32)
y = np.array(y, dtype=np.float32)
plt.plot(x,y)
Or use list comprehension to convert the values to a float:
x = ['1.34511','0.0234','-0.0890']
y = ['0.0987', '0.8763', '-0.0762']
x = [float(val) for val in x]
y = [float(val) for val in y]
plt.plot(x,y)

You might use
x=map(float,x) instead of list comprehension.
