I think that the only thing you are missing is to set the AutoRange property to false. However, I think that you should rework your project and not use RadChart and sparklines.
1. We have two charting solutions - old RadChart and new RadChartView
. The RadChartView is actually a set of controls (RadCartesianChart
, ChartDataSource). The new control has a much better performance
, better zooming
abilities, it resolves many of the limitations that the old RadChart has, it is very easy to set up and is very flexible.
2. While usually using a sparkline with a timebar makes sense, in your case I think you will find it easier if you have a RadCartesianChart under the timebar. We have an SDK demo
that demonstrates exactly this. This way you will not have the need to work with sparklines in one control and line series in the other. You will be working with line series in both controls.
