Not really a question, more of an example of strange behaviour that had me a bit baffled.
I have a document with a Google map (scatter chart) and I was trying to change some of the properties to make things visible/invisible and different colours. I was finding that nothing I was doing was making any difference.
I decided to try changing the 'Max Bubble Size' (on the Presentation tab) which I know I have used to change the size of the points on the chart. This wasn't working either which was a bit frustrating.
In the end I copied the Google map object and removed the original. I pasted the object back in and it works! I can change the properties and it now reflects in the chart.
