If you are willing to get your hands dirty and dig into the SVG the chart is based on, you might be able to get this to work (note that IE < 9 do not use SVG, so this might not work for all browsers). You'll need to get the contents of the chart div's inner iframe, and search it for 'text' nodes. You can then assign a 'click' event listener to the nodes, and navigate to different URL's depending on the text node's contents. Something like this (with the help of some jQuery): http://jsfiddle.net/yW7JM/
I stored the URL in the DataTable object, hid it with a DataView, and fetched it again by filtering the first column on the text node's value. Potential pitfalls are that you could have text nodes with duplicate data that trigger "links" where you don't want them or duplicate axis values that you want linked to different URLs. If you study the CSV closely, you might be able to find other features that discern axis labels from other text nodes and use those to filter the node selection even further, which would help avoid the first pitfall. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
