tooltips using ValueMarkers

[evilgeenius]

Is it possible to create tooltips and linkgenerators over ValueMarkers?
So when the mouse is moved over a value marker i can click a link..

I can do it with an ordinary XY dataset but i have no idea with my value markers.

Any help is greately appreciated
Thanks

It isn't supported, but only because the code that draws these markers doesn't add a ChartEntity for it. With a little refactoring this could be added, and it would certainly be a nice addition.

Was this ever implemented by anyone? I want to be able to set a different cursor when over a marker to indicate it is draggable.

It looks as though the latter is not simple to do but for the moment I intend to simulate it with a line that I move over the chart panel and re-draw the marker when the mouse button is released.

No, it hasn't been implemented. What's needed (in XYPlot for example) is to replace the drawDomainMarker() and drawRangeMarker() methods with variants that accept a PlotRenderingInfo instance - then check if the owner (ChartRenderingInfo) has a non-null EntityCollection...if it does, then add a new ChartEntity for each marker drawn. You'll probably want to extend the ValueMarker and RangeMarker classes to carry optional tooltip and URL details, which you can use to populate the ChartEntity. I don't think this is a really difficult change, but just requires a little care to ensure that it doesn't break the existing API (deprecating some methods is OK).
