Export marine thermal insulation to full pgf

Question

I am trying to build a heat map with the sea and export it to pgf for easy import into latex. This works more or less, the only thing that bothers me is that the color bar is exported as an additional png.

So, if I run export to pgf, I get the following:

• test.pgf
• test img0.png

This is definitely undesirable since png doesn't scale well. Some MWEs:

import matplotlib.pyplot as plt
import pandas as pd
import seaborn as sns

df = pd.DataFrame.from_csv("test.csv", sep=',')

sns.set('paper', 'white', rc={'font.size': 10, 'axes.labelsize': 10, 'legend.fontsize': 8, 'axes.titlesize': 10,
                              'xtick.labelsize': 8,
                              'ytick.labelsize': 8, "pgf.rcfonts": False})
plt.rc('font', **{'family': 'serif', 'serif': ['Times']})
plt.rc('text', usetex=True)
fig = plt.figure()
ax = sns.heatmap(df, linewidths=.5)
fig.savefig('test.pdf')
fig.savefig('test.pgf')

And the contents of test.csv:

0,1,2,3,4
1,1,1,1,1
2,2,2,2,2
3,3,3,3,3

Does anyone have a solution to include a colored string in pgf output?
