Hi.
I have XamChart in my project and it acts like this:
step1
step2
step3
But I want to reach this behaviour in the middle (step2):
So I need tooltip moving along the line with keeping last point value inside the label-box.
It looks like some kind of fusion of ItemToolTipLayer behaviour with useInterpolation = true and with useInterpolation = false.
So what I need to do?
Thanks,
Evgeniy.
Hi Evgeniy,
Tooltips in the XamDataChart are tied to the data point location in the series. You can see these locations if you turn on markers on your StepLineSeries. Unfortunately there are no data points along the edges of the steps so the tooltip won't show on those edges. As for the ItemToolTipLayer, this tooltip transitions from point to point in a straight line and it currently does not support following along the line as it moves from point to point. As such this has been determined to be a new product idea for the XamDataChart. If you wish to see this functionality included in a future version of the chart I recommend that you submit this as a new product idea here: http://ideas.infragistics.com
Thank you for explanation. I solve my issue by adding pair-point for each series item like this:
x - points of source collection; o - additional points
Very cool! That would definitely do the trick.
