Re: Generating image thumbnails for charts

[asgallant]

There is no built-in functionality for exporting to images.

Generally, though, if you are using the non-flash charts (ie, not AnnotatedTimelines, GeoMaps, or MotionCharts), and your data sets are reasonably small (not 1000's of data points), there are no performance issues when rendering multiple charts.  I have some pages that render upwards of 30 charts with no issues, but YMMV.  I'd give it a try and see how well it works before looking into harder solutions.

I'm using the Google Charts API to generate a number of Column Charts on a site.

What I'd like to do is on the home page present a series for static image thumbnails, say 100x80, of selected charts. Probably 8 to 10 charts.

The charts do not change that often - so generating new images every day or so is fine.

I could use the API to generate small charts from the data, but I think this may cause a performance issue. I'd like the home page to render quickly.

I couldn't find an 'export' method in the API and the only solution I could find was http://www.battlehorse.net/page/topics/charts/save_google_charts_as_image.html but there are caveats

Does anyone have any ideas or know if there is a hidden API function call to generate images.

Thanks.
