You can use scatter_matrix in pandas.plotting to draw a scatter matrix chart: In [83]: from pandas.plotting import scatter_matrix In [84]: df = pd.DataFrame(np.random.randn(1000, 4), columns=["a", "b", "c", "d"]) In [85]: scatter_matrix(df, alpha=0.2, figsize=(6, 6),...
import pandas as pd import matplotlib.pyplot as plt Figure和Subplot matplotlib的图形都位于Figure(画布)中,Subplot创建图像空间。不能通过figure绘图,必须用add_subplot创建一个或多个subplot。 figsize可以指定图像尺寸。 #创建画布 fig = plt.figure
Histogram can also be created by using theplot()function on pandas DataFrame. The main difference between the.hist()and.plot()functions is that thehist()function creates histograms for all the numeric columns of the DataFrame on the same figure. No separate plots are made in the case of the...

Then. df.plot is used to plot the two columns of the data frame in the y-axis and the label of the x-axis is specified to be the index of the data frame. The dates are converted into a compatible format using the strfttime function. The title of the graph is given as ‘Using ...
, To have a contour plot, z needs to be 2d matrix with all values for the points (x,y).You can think the data needed for a contour plot, as a DataFrame where index is x, columns are y and values are z.So z needs to be a 2d array of shape (x.size, y.size).. Since ...
