I figured out how to create custom html hints using roles via googleVis . I can easily modify the content using html, but I cannot figure out how I can control the tooltip itself.
My problem arose because some custom tooltips went beyond my chart area, and I tried (unsuccessfully) to find a way to control the tooltip position. Idealism I would like to make them behave exactly like the default tooltips behave in googleVis (always stay inside the chart area).
When I later implemented the same concept in a line chart, I found that I had another problem. The tooltip falls on the line, so I don’t see what the exact point is that refers to the tooltip.
Is it possible, for example, to keep the default callout style of the googleVis tooltip and change the content using HTML?
Also, do you know if there is a way to control advanced tooltip properties such as border and background colors?
