The below code will create a box plot which shows the price distribution for all the four different property types. This new object is essentially opaque to the the details and the data for the patches used to draw the bars isn't available from which to compute the individual bar positions so labelling bars as this example does won't work. Understand df. However, the bar graph might hide important information (remember, the scatter plot revealed some outliers). This is the core difference between Bokeh and other visualization libraries. Because the total by definition will be greater-than-or-equal-to the “bottom” series, once you overlay the “bottom” series. I have not used ggplot in R so there was a bit of a learning curve.
