So you know what you're looking at, in the default settings as I've published it, the x-axis is the reach, while the y-axis displays hours. So a station in the top right-hand corner would be an elderly male station, while a station in the bottom left would be a young female station.

The size of the circle is related to that service's average hours.

I used to have different settings, but unfortunately the Google charts have been changed, and I can't currently set defaults.

However all these settings are changeable. Just choose a measure from the dropdown and get the chart into your preferred format.
