Filtering problem (bug?)

In my codebehind, I am adding a bunch of data points (65k) to a line graph:

 

spectraPlot.AddLineGraph(ds,
new Pen(Brushes.LimeGreen, 1),
new CircleElementPointMarker
{
    Size = 5,
    Brush = Brushes.Red,
    Fill = Brushes.Orange
},
new PenDescription("Data"));

I am stepping through the code for AddLineGraph in Plotter2DExtensions.cs, and see where the FrequencyFilter is being added to the LineGraph:

graph.Filters.Add(new FrequencyFilter());

But there appears to be no filter on the Markers?  This is killing my app, since no matter how I filter my data, there does not appear to be any difference in the number of Markers shown: in my case all 65k.  

Is this a bug or am I missing something?

I am also having the same issue...

Adding Markers is killing the performance.

Any means to apply filter on markers?

I am also having performance related issues with markers. Is there anything that can be done about it?

Same here - I am actually trying to display 4 line charts, each with 65k points.  Performance is terrible as a result once markers are added.  Any advice??
