需要使用熊猫系列和numpy数组创建图

Question

I have a panda time series (x) with time index t and numpy array (y) of same length. i need to create a plot of x,y on y axis and time (t) on x axis.

x.shape (320,)    
y.shape (320,1)

i tried converting numpy array but it gives me an error(Data must be 1-dimensional).

pd.Series(y,index=x.index)

Answer 1

Assuming that your x is a panda series and y is a numpy array

import matplotlib.pyplot as plt
plt.figure()
plt.plot(x.index.values, y, label="y")
plt.plot(x.index.values, x.value, label="x")
plt.legend()
plt.show()
