My users are saying that on iPad and iPhone where to see a tooltip you are required to click rather than hover it is too difficult to click on the marker.
Markers are by requirement not visible but the users still need to click the correct position on the line to show the Tooltip. It seems that the area to click is very precise and very small. It doesn't seem an issue on Desktop where Hover is available to show tooltip on Category series.
I'm looking for a way to make the clickable are bigger/easier for mobile devices. I found a similar forum question for a bar chart. I have put it into the the below Dojo but am struggling to make it apply to markers on a line chart.
