    Default Unanswered: Highlight specific points on a line chart

    I want to highlight certain points on a chart that have some significance and show a label for that point.

    I see that markerConfig allows us to highlight all points on the chart. Is there a way to customize its behavior?

    Update -

    I figured out how to highlight a point by using the highlightItem() method, but when I click on another point on the chart (I have iteminfo interaction enabled), the original highlight doesnt persist. I would like to have that point always highlighted.

    You would have to execute hightlightItem again.
