This is a feature suggestion: I think it would be trivial to take a given chart say:
http://chart.apis.google.com/chart?cht=bhs&chs=200x125&chd=s:ello&chco=4d89f9 add a url parameter, such as chmd=map|xml|json chmd would indicate that you wanted Chart metadata, not an image back. So you would instead get a html (image map) <map> of interesting regions on the png version. or xml encoded metadata, or json encoded metadata. This would allow you to include hovers and clickthrough actions via other javascript libraries, or html's built in <map> tag. In most cases you would make two chart api calls for this purpose, one for the image, and one for the metadata. You would feed the metadata to a javascript engine to generate hover div charts. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google Chart API" group.
