Change Matplotlib Axis Settings

How do I get control over the axis settings of a pyplot plot. I have simply done pylab.plot(*self.plot_generator(low, high)) pylab.show() and I get this which is what I w

Solution 1:

# createsome data
x = np.linspace(-np.pi,np.pi,100)
y = np.cos(2.5*x)

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x,y, mfc='orange', mec='orange', marker='.')

# using'spines', newin Matplotlib 1.0
ax.spines['left'].set_position('zero')
ax.spines['right'].set_color('none')
ax.spines['bottom'].set_position('zero')
ax.spines['top'].set_color('none')
ax.spines['left'].set_smart_bounds(True)
ax.spines['bottom'].set_smart_bounds(True)
ax.xaxis.set_ticks_position('bottom')
ax.yaxis.set_ticks_position('left')

ax.axhline(linewidth=2, color='blue')
ax.axvline(linewidth=2, color='blue')
show()

Solution 2:

To set start of x-axis to 0:

pylab.xlim(xmin=0)

To set start of y-axis to 0:

pylab.ylim(ymin=0)

Put one of these lines (or both if you'd like) after the pylab.plot call.
