No, unfortunately the WeeWX image generator cannot do that. You might be able to achieve such an effect using a 3rd party charting package such as Highcharts.

In general you need to have WeeWX produce whatever data the charting package requires, that could be as simple as a JSON format data file produced via a WeeWX report or it could be something more complex. You would need to put the necessary HTML/JavaScript/PHP code required by the charting package to render the chart in the correct Seasons template file. All fairly straightforward but can be quite involved depending on your skills. Certainly much more involved than adding an additional WeeWX image generator generated plot.
