Tapping on data points displayed using a scatter series is too difficult compared to tapping a point of the same size displayed using a line series. After some investigation, we found that to successfully tap a line series point the tapped portion of the screen must touch the edge of the data point. For scatter series however, the center of the touched portion of the screen must touch the edge of the data point.
This significantly reduces the "effective" tapable area of the scatter series data points and negatively impacts our user experience.
- On an android device, in settings -> Developer Options: enable the Show Touches option.
- Open a project that includes a scatter series.
- Begin tapping the screen getting closer and closer to the center of the scatter series data point
The tap will register as soon as the taped area overlaps the edge of the data point.
The tap does not register until the center of the taped area overlaps the edge of the data point.
