Hi, i use SfChart to display line series of data points.
It has the following settings and all of them are in the PCL.
SplineSeries lineSerie = new SplineSeries();
ChartDataMarker dataMarker = new ChartDataMarker();
lineSerie.DataMarker = dataMarker;
dataMarker.ShowLabel = false;
dataMarker.ShowMarker = true;
dataMarker.MarkerType = DataMarkerType.Ellipse;
dataMarker.MarkerWidth = 10;
dataMarker.MarkerHeight = 10;
dataMarker.MarkerColor = Color.White;
dataMarker.MarkerBorderColor = Color.FromHex("#B2B2B2");
dataMarker.MarkerBorderWidth = 5;
lineSerie.Label = "DataPoints";
lineSerie.EnableAnimation = true;
lineSerie.AnimationDuration = 0.8;
lineSerie.EnableTooltip = true;
lineSerie.TooltipTemplate = new DataTemplate(typeof(ChartPointToolTip));
lineSerie.ColorModel.Palette = ChartColorPalette.Custom;
The chart works on android, but on iOS if there only one point in the serie nothing is displayed. The x and y minimum and maximum are within range and the chart seems fine but the single data point is not displayed.
