I’m using line series with LineDrawMode.Gaps, if dataseries contain single points with gaps, chars looks empty. I found only one way to see the data points – set PointMarker, but in other cases without gaps, point marhers are not needed for the line series. Is there any way to show single points when gaps are presented w/o point markers or paint point markers only for single series?

                    var renderableSeries = new FastLineRenderableSeries()
                        Stroke = DataManager.Instance.GetRandomColor(),
                        DataSeries = dataSeries,
                        StrokeThickness = 2,
                        DrawNaNAs = LineDrawMode.Gaps,
                    //renderableSeries.PointMarker = new EllipsePointMarker() { Width = 5, Height = 5, Fill = renderableSeries.Stroke, Stroke = renderableSeries.Stroke, StrokeThickness = 2 };

    Hi Ivan, please explain further (the data you are appending to chart). From my understanding so far, you have some datapoint like x x x x o x x x (where x = NaN, or empty point, and O = a real point) and the chart is empty. Wouldn’t this be expected? You can’t draw a line segment with one point.

    The example added below.

I attached the sample.

Observed behaviour: the series {4,2} is not visible. If uncomment line renderableSeries.PointMarker, the series is visible.
Expected behaviour: visualize {4,2} by same way as with PointMarker, but w/o PointMarkers for other points connected with lines. Or how set point marker only for {4,2}?
