How to get which bar and its index I am hovering? #365

Supposedly I can bind event to canvas then I can get the bar I am hovering by: var bars = chart.getBarsAtEvent(evt); in original Chart.js. How to do it with ChartNew.js?

Besides, there is no way for developer to get the index of bar hovering, is it provided in ChartNew.js?

Not sure that I understand what you want but check following :

See Samples\mouse_detect_position.html (this is a new sample; You will have to redownload the last version of ChartNew.zip). see also Samples\annotateFunction.html
