Can't get POTM parameter to load in PointSeries example

[jonblower]

If I load the PointSeries example in the Playground, the POTM parameter doesn't get displayed. The PSAL parameter works fine.

The UI is not great there but it is actually loaded. To switch between them use the drop down above the plot.

Ah yes, I was confused by the UI. Clicking on the PSAL checkbox in the legend loads up the plot, but clicking on POTM doesn't - you have to click on the black dot to bring the plot up in this case.
