How to change x- and y-axis ticks with categorical variables in Python matplotlib?

I want to plot the average price (numeric variable) of cars against two categorical variables, body-size (“convertibe”, “hardtop”, “hatchback”, “sedan”, “wagon”) and drive-wheels (“4-wheel drive”, “front wheel drive”, “rear wheel drive”) in a heatmap. Dataframe: drive-wheels body-style price 0 4wd hatchback 7603.000000 1 4wd sedan 12647.333333 2 4wd wagon 9095.750000 3 fwd convertible 11595.000000 4 […]
