Three variables as heatmap

Question

I want to plot my data as a heatmap which has the following structure:

X = [1,1,1,1,1,1,1,1,1,1], Y = [1,2,3,4,5,6,7,8,9,10] Z = [0.2, 0.33, 0.1, 0.25, 0.0, 0.

Answer 1

I hope your data is just an example because it will look funny (it's more a sequence of strips; the x-dimension is constant).

I would recommend the usage of pandas (general data-analysis) and seaborn (matplotlib-extensions) which makes it a bit nicer.

Code

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
X = [1,1,1,1,1,1,1,1,1,1]
Y = [1,2,3,4,5,6,7,8,9,10]
Z = [0.2, 0.33, 0.1, 0.25, 0.0, 0.9, 0.75, 0.88, 0.44, 0.95]
data = pd.DataFrame({'X': X, 'Y': Y, 'Z': Z})
data_pivoted = data.pivot("X", "Y", "Z")
ax = sns.heatmap(data_pivoted)
plt.show()

Output
