Domain and Range markers

[permiakover]

Hello, what is a rational way to add markers to the line chart with text label?

[HanSolo]

Do you mean a marker at a random point of the line? There is nothing available yet. Can you add a code snippet and a screenshot with some example to this issue? With that I could maybe implement something.

here is a example of domain markers over AreaChart

here is a example of domain markers over 'combined HeatMap like chart'

From my point of view, it's a line(width, color, stroke) that has X or Y value related to domain or range axis, with or without label.
If it possible to get or sync chart values and canvas values - it could be implemented as overlay pane

I've finally found some time to add a prototype for markers in the jdk17 branch. You will find a demo in the ChartTest class in the test package

Regarding adding MarkerBuilder. After upgrading from 17.1.25 to the latest 17.1.27, the crosshair, and tooltip is no longer working. Tested in the ChartTest class in the test package.

Thx for the heads up, will take a look at it 👍🏻

Thanks for setMouseTransparent(true). Is it possible to alter MarkerBuilder to accept AxisType.TIME value?
