Hello,
I want to click the marker (or maker label) to get the X value of this marker, How can I detect the click event on a ValueMarker?
until now, I only see there is a listener "ChartMouseListener" which only listen the click event on the chart, it's not enough.
Thanks a lot.

You can´t do that with a ValueMarker. 1.5 years ago, I have written a couple of annotation classes that can be used as Marker replacements. Annotations do support the creation of entities. If you click anywhere on the chart, you can check whether ChartMouseEvent.getEntity() returns an instance of AxisAnnotation, and move forward from this point on.
