Hi,
Thank you for your interest in Essential Chart.
Essential Chart supports displaying Tooltips for the points (bars in some Chart types) in a Chart series. The PrepareStyle event of the ChartSeries can be handled to provide point specific tooltips.
Please see the sample linked to below for an example:
