The Impulse Chart Type

Stem charts (or Impulse Charts) are provided by the FastImpulseRenderableSeries type. This draws a single line from ZeroLineY to the X-Y value with an optional PointMarker.

Examples for the Impulse Series can be found in the SciChart WPF Examples Suite which can be downloaded from the SciChart Website or our SciChart.WPF.Examples Github Repository.

NOTE: For a detailed description of the PointMarker API, see  Point Marker API-BaseRenderableSeries.Pointmarker

To declare a FastImpulseRenderableSeries use the following code:

Declare a FastImpulseRenderableSeries in Xaml / Code Behind

Declare a FastImpulseRenderableSeries
Copy Code 
<!-- where xmlns:s="http://schemas.abtsoftware.co.uk/scichart" -->
<s:SciChartSurface>

    <s:SciChartSurface.RenderableSeries>
             <s:FastImpulseRenderableSeries x:Name="rSeries" AntiAliasing="True"
                           StrokeThickness="1"
                           Stroke="Blue"
                           ZeroLineY="0.0">
                    <s:FastImpulseRenderableSeries.PointMarker>
                           <s:EllipsePointMarker Width="7" Height="7"/>
                    </s:FastImpulseRenderableSeries.PointMarker>
             </s:FastImpulseRenderableSeries>
       </s:SciChartSurface.RenderableSeries>

    <!--  XAxis, YAxis omitted for brevity  -->

</s:SciChartSurface>

// Code Behind, e.g. in OnLoaded event handler, set the DataSeries
var dataSeries = new XyDataSeries<double, double>();
for(int i = 0; i < 100; i++)
       dataSeries.Append(i, Math.Sin(i*0.2));
rSeries.DataSeries = dataSeries;

Declare a FastImpulseRenderableSeries in Pure Code

Declare a FastImpulseRenderableSeries
Copy Code 
// Declare the scichartsurface
var sciChartSurface = new SciChartSurface();
// ...
// Declare and add a Column Series
var impulseSeries = new FastImpulseRenderableSeries()
{
    Stroke = Colors.Blue,
    StrokeThickness = 2,
    PointMarker = new EllipsePointMarker() { Width = 7, Height = 7 },
    AntiAliasing = true,
    ZeroLineY = 0.0,
};
sciChartSurface.RenderableSeries.Add(impulseSeries);

// Set some data
var dataSeries = new XyDataSeries<double, double>();
for(int i = 0; i < 100; i++)
    dataSeries.Append(i, Math.Sin(i*0.2));
impulseSeries.DataSeries = dataSeries;

 

 

NOTE: You can also declare RenderableSeries using full MVVM (series ViewModels). Please see MVVM DataSeries / RenderableSeries API for more details
