How can we set the distance or gap between individual bars or chartseriesitems? Also when we set activeregion->tooltip property, can we use any skins to show various stylish tooltips as we hv in case of radtooltip? I would also like to add tooltip to a marked zone by finding out its active region. Right now rad chart doesnt support tooltip for marked zone. But is there any way or any logic can be written to achive this functionality?
