How to plot the empirical distribution function in oxyplot?

Question

I have data that are points of the empirical distribution function

ICollection<DataModelXY> data {get; set;}

class DataModelXY
{
  public double X {get; set;}
  public double Y {get; set;}
}

I need do draw function like that

or that

Alas, in the oxyplot there is only StairStepSeries which builds the wrong thing

Need that without lines under red cross:

Answer 1

There are two properties on StairStepSeries, VerticalLineStyle and VerticalStrokeThickness.

Try to set VerticalLineStyle="None" (for some reason None doesn't work for me) and if it won't work you can set VerticalStrokeThickness="0".

<oxy:Plot>
    <oxy:Plot.Series>
        <oxy:StairStepSeries ItemsSource="{Binding Points}" 
             VerticalLineStyle="None" VerticalStrokeThickness="0">
        </oxy:StairStepSeries>
    </oxy:Plot.Series>
</oxy:Plot>
