有没有办法在 python （Matplotlib）中设置 y 轴的限制？

Question

I am new to Python (v 3.7) and currently working on preprocessing pupil data. I am working with the following code:

    x = np.arange(timepoints.shape[0])/sample_rate
    f = pl.figure(figsize = (10,3.5))
    pl.plot(x, pupil)
    pl.xlabel('Time (s)')
    pl.ylabel('Pupil size')
    sn.despine(offset=10)

Using the above code, I receive the following output:

I would like the y-axis limits to be within the range of 0-1000. I have tried ylim and this does not seem to work and I still receive the same output.

Here is the new figure with the following code:

     x = np.arange(timepoints.shape[0]) / sample_rate
     f = pl.figure(figsize = (15,3.5))
     pl.plot(x, pupil)
     pl.yticks(np.linspace(0, 1000, 10))
     pl.xlabel('Time (s)')
     pl.ylabel('Pupil size (a.u)')
     sn.despine(offset=10)

enter image description here

I've tried playing around with the numbers etc. but it still doesn't seem to cooperate.

If you would have googled it before, it would be better. There is a way to do it,
