I am trying to plot the numpy arrays x_train and y_train. I am using matplotlib’s plot function and I would like to pass an argument to increase the size of the data points. Here is my code:
x_train = np.array([0. , 0.10526316, 0.21052632, 0.31578947, 0.42105263,
0.52631579, 0.63157895, 0.73684211, 0.84210526, 0.94736842,
1.05263158, 1.15789474, 1.26315789, 1.36842105, 1.47368421,
1.57894737, 1.68421053, 1.78947368, 1.89473684, 2. ])
y_train = np.array([0.2260415, 0.08966768, -0.02649684, -0.1024971, 0.14580953,
0.03593453, 0.14398569, 0.30298584, 0.51058752, 0.43602841, 0.50852418,
1.05403315, 1.27155675, 1.38071476, 1.62995731, 1.6434204, 1.64367346,
1.54763514, 1.47964281, 0.97544995])
plt.figure(figsize=(20,10))
plt.plot(x_train, y_train, '*', color='black', label='Train values with noise')
>Solution :
Use markersize (shortcut: ms):
plt.plot(x_train, y_train, '*', color='black', label='Train values with noise', ms=12)
