Hi Richard,

when you're using onmouseout event to hide tooltips and you have several charts (line/bar) and one of them is empty (no data, ie it is a dynamically refreshing line chart and not containing anything now) the line draw function drop javascript error, when try to display tooltip on other chart.

My temporary solution: you have to check the data length in the event functions and if there is no data don't call the redraw.
