Hi, I was wondering if it is possible for a custom datasource to also return metadata that is not used to display the chart but is used to update a separate element on a page?
What I'm trying to achieve here is that we would like to have multiple charts showing different activities on a page but then also to have a text summary of the data that is in those charts e.g. a chart that shows revenue by day and then also a text element that shows the exact values of 'average revenue', 'variance against target' etc. Some of these values would be generated from the values in the charts but others would be independent pieces of data. It would be possible to return this data as an extra element in the datasource as part of the 'Wire Protocol' but it seems that this extra data is not available after the "google.visualization.Query" has returned and called the callback function for handling the data. Is there any way to achieve this, or do I need to make separate requests to get metadata back? Apologies if this has been asked before and answered - I had a look and couldn't see anything similar. cheers Dan -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
