When displaying a curve, we implicitly assume that one point follows another—our data is the time series. Of course, this does not always have to be the case. One point of the data can be independent from the other. A simple way to represent such kind of data is to simply show the points without linking them.

plt.scatter(data[:,0], data[:,1])
plt.show()

The preceding script will produce the following graph:
