Removing frame while keeping axes in pyplot subplots

Question

I am creating a figure with 3 subplots, and was wondering if there is any way of removing the frame around them, while keeping the axes in place?

Answer 1

You can achieve something like this with the axis('off') method of an axis handle. Is this the kind of thing you are after? (example code below the figure).

fig, ax = plt.subplots(7,1)

t = np.arange(0, 1, 0.01)

for i, a in enumerate(ax):
    a.plot(t, np.sin((i+1)*2*np.pi*t))
    a.axis('off')

plt.show()
