 Let’s change that last pie chart into a bubble chart by replacing the <<pie_fn, pie>> function with the <<plot_fn, plot>> function. This is possible because both functions can accept a `pointseries` data type as their _context_. Switching the functions will work, but it won’t produce a useful visualization on its own since you don’t have the x-axis and y-axis defined. You will also need to modify the <<pointseries_fn, pointseries>> function to change its output. In this case, you can change the `size` argument to `y`, so the maximum price values are plotted on the y-axis, and add an `x` argument using the `@timestamp` field in the data to plot those values over time. This leaves you with the following expression and produces a bubble chart showing the max price of each state over time:
