Drawing 4 Matplotlib
More than one subplot
FIG line 2
Code as follows:
The first array is a plot function of the value of the horizontal axis, the longitudinal axis of the second array value, which is a straight line, a polyline;
The last parameter is constituted by two characters, respectively, line style and color. The former is a straight red, which is the green dotted line.
3 Scatter
Code as follows:
This figure includes three sets of data, each set of data contains the coordinates of the 20 random positions
Parameter c represents the color point, s is the size of the dots, alpha transparency
Pie Chart 4
Code as follows:
Numerical data is a set of random data comprising 7
FIG specified by the tag labels
autopct precision format specified value
plt.axis ( 'equal') provided a consistent size axis
plt.legend () indicates the legend to be drawn (top right of figure below)
5 bar
Code as follows:
This figure shows a set of results comprising 7 random values, each value is [0, 100] of the random number
Their color is generated using a random number. np.random.rand (N * 3) .reshape ( N, -1) indicates Mr. as 21 (N x 3) random numbers, and then assemble them into 7 lines, then each row is the number three, which corresponds to the three components of the color.

6 Histogram
In the above code, [np.random.randint (0, n, n) for n in [3000, 4000, 5000]] generated array contains three arrays, of which:
The first array contains 3,000 random numbers, the random numbers range is [0, 3000)
The second array contains 4,000 random numbers, the random numbers range is [0, 4000)
The third array contains 5,000 random numbers, the random numbers range is [0, 5000)
