Re: Legend and annotation tooltips

How can I determine using mouse coordinates what is the title hovered in the current time in the legend box?

Legend and annotation tooltips

Hello,

I have to show tooltip to the user when he hovers a legend or annotation on the chart, but I have no idea if it possible to do?
I tried to handle MouseOverOn/Off events for [sampleDataSeries]. Title object, but it looks like it doesn't work.

Could I display walls without adding more points(zero points around all array) in SurfaceMeshSeries3D?
