Question

A google.visualization.BarChart will not show tooltips for me in Firefox, but shows them in Chrome.

I am using Firefox 4.0.1 on Linux.

Answer 1

This might be related to issue 598 “Google Chart Tools: tooltip/line not shown on firefox using base tag” at google-visualization-api-issues which is reproduced when a base tag differs from a page location.

A possible solution could be to use jQuery to change the href attr of the tag.

jQuery("base").attr('href', document.location);
chart.draw(data, options);
