I have two variables which are represented by a `Numpy` array of size `1000000x1`. I would like to use `matplotlib` to plot both of them in the same plot. However, If I proceed and plot them together the result is unintelligible since I have so many values I cannot really understand a lot. Is there a way that I can downsample and plot a more sparse representation of both variables?

```
plt.plot(acc1) #acc1 contains 10000000 samples
plt.plot(acc2) #acc2 contains 10000000 samples
plt.show()

```
