绘制散点图

Question

House_prices = [10050, 42300, 50206, 105000, 22350]
Num_rooms = [4, 5, 6, 10, 12, 2]

code

#This is the code that I have tried:
x = df.House_prices
y = df.Num_rooms
plt.scatter(x,y)
plt.show()

I want to plot "House_prices" and "Num_rooms" into a scatter plot. But I encountered this error 'list' object has no attribute 'House_prices' I don't know whats wrong and I need some help to find out what is wrong. Which part am I wrong? is it the top half: "x = df.House_prices" and "y = df.Num_rooms" ?

Answer 1

So, first create a x-axis array or list. I used numpy for that.

import numpy as np
x = np.arange(0,len(House_Prices),1)
x1 = np.arange(0, len(Num_rooms),1)

fig=plt.figure()
ax = fig.add_axes([0,0,1,1])
ax.scatter(x,House_Prices)
ax.scatter(x1,Num_rooms)
plt.yscale(value='log')
plt.ylim(0.5,1e5)
plt.show()
