We are trying to display a very large line data set and it seems SciChartOverview would be a good way of visualizing full range of data. Let’s say we have 10 lines of millions data points each to be displayed. The idea is to display down-sampled version of these 10 lines in SciChartOverview, and display full-sampled version in the parent surface with x range matched with scroll bar range in SciChartOverview. When user moves the scroll bar or changes its range in SciChartOverview, it will reload data into the parent surface.

Is there a way to achieve above? Thanks.

I’m having two synced charts, one SciChartSurface and a SciChartOverview.

The SciChartSurface is bound via the SeriesSource to two ChartSeriesViewModels each consisting of a XyDataSeries<DateTime,double> and a FastLineRenderableSeries.
The important thing here is that the FastLineRenderableSeries has the IsDigitalLine property enable – to well – get a nice digital / stepped line instead of straight connections.

The SciChartOverview is bound to the SciChartSurface via the ParentSurface property. All works fine, except that the data series on the SciChartOverview is drawn with straight connecting lines instead of the digital / stepped line. Unfortunately I found no way to explicitly specify an IRenderableSeries or to reuse the ChartSeriesViewModel on the SciChartOverview.

I also tried to use the DataSeries property directly, but of course, this just defines the IDataSeries and not the IRenderableSeries on which I could set the IsDigitalLine property.

Is there any way to get the SciChartOverview to draw a digital line or at least just use the ChartSeriesViewModel bound to the associated ParentSurface?

Hi Guys

I am using an ItemsControl to display a collection of SciStockCharts. I want to be able to use a single SciChartOverview (not part of the Item Template) to set the visible range on all of the charts displayed in the ItemsControl. Is this possible and if so how would I go about achieving it.

Thanks in advance
