My DataFrame line index and column index store x
and y
values, while the data values are z
values, i.e. f(x, y)
.
Let's take an example:
import pandas as pd
df = pd.DataFrame([[150, 120, 170], [190, 160, 130]],
index=[2, 4], columns=[10, 30, 70])
print(df)
# 10 30 70
# 2 150 120 170
# 4 190 160 130
then f(4, 30)
is 160
.
I would like to make a 3D plot of function f
. I don't really mind if it looks like a 3D histogram or a surface plot - both answers would be appreciated.
