asgallant, thanks for all your help today. With regards to this thread - and also the one about displaying a pie chart in the tooltip and piechart legends - I have decided that the Google Visualisation tooltips are not designed to do what I need for my project. However, the GV-API is robust enough to allow me to implement the workaround of creating my own tooltips.
I'm going to add listeners for onmouseover/onmouseout and draw my own tooltips by setting tooltip.trigger: 'none'. These can be as complicated as I like. However, the GV-API obviously contains some code to work out *where* to display the tooltips (i.e. x,y absolute positions which intelligently take the size of the tooltip window into account). I'd like to re-use this code, how can I access it? -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
