Suggestions for using google line charts on VERY large datasets.

[Tom Cumming]

I have a large database where a user could select a range of data that could return millions if datapoints in X. (time). What would the best way to handle this? I'm thinking along the lines of averaging chunks down to the number of pixels the chart is wide (i.e, a chart 1000 pixels across that is plotting 1 years worth of data, I'd average the data into 1000, 1/1000'th of a year data points).

Any advise?

Oh, I should have said that I'd do the data reduction on the server side, so that I only shove 1000 data points up to the client.
