"Draw a straight line" our first (minimal) machine learning application

Next

We already have the raw data (x, y), which is shown on the diagram before processing the data, which uses the Matplotlib module.

First of all:

Import Matplotlib.pyplot as Plt

From first import x, y

To mark XY in a coordinate system I started thinking about using the plot () function to try it out:

Plt.plot (x, y)

Plt.show ()

Out of this is the way:

Like the ECG, plot () is to connect the dots, not what we want, or to make a point chart with the discrete function scatter () in the book.

Plt.scatter (x, y)

Plt.show ()

That's it, just the blue dot is a bit big, not very clear change

Plt.scatter (x,y,s=10)

Plt.show ()

Compare yourself to the difference.
