Multiple tooltip is not displayed when adding dynamic points in charts

Question

Multiple tooltip is not displayed when adding dynamic points in charts

I have a quick chartjs tooltip to display the X and Y axis values in the tooltip. But when data points are added dynamically, the tooltip is not visible.

Any help would be appreciated.
