I would like each fluid to have a different color and then be able to pass the matrix to png
f, ax = plt.subplots(figsize=(20, 5))
sns.heatmap(fluidos_frame, annot=True, linewidths=.5,
ax=ax,cmap = 'viridis')
plt.xlabel('Th[K]')
plt.ylabel('m[kg/s]')
plt.savefig(path + 'Matrix_r124_MW.png')
ValueError: could not convert string to float: 'R134a'
