Quick question regarding WinForm Line charts

[preintel]

I am getting shaded areas below the line chart when using LineSeries instead of LineSeries, not sure how to disable the shaded area and only show a simple line.
Also when adding a separate line series with a different geometry to the first one, the second series does not show the icon in the legend area, not sure why this happens.

Is there a way to add the properties to a series when initializing it, for example to set the Fill property and where can I find a list of all the properties of a series (seemed to be more straight forward in the LiveCharts version one source code)...

new LineSeries<DateTimePoint>
                                                         {
                                                              Name = ticker+" - RSI Chart",
                                                              Values = dPList,
                                                              TooltipLabelFormatter = p => $"{ticker}, "+(new DateTime((long)p.SecondaryValue).ToString("MM/dd/yyyy hh:mm tt"))+$", RSI: {p.PrimaryValue:N2} "+" ",
                                                              Fill = LiveChartsCore.Drawing.LvcColor.FromRGB(255, 255, 255),
                                                              Fill = Brushes.Transparent
                                                         }

Found the solution, simply set the Fill property to null when creating a chart:

cartesianChart1.Series = new List<ISeries>
                                                     {
                                                          new LineSeries<ObservablePoint>
                                                         {
                                                              Name = ticker+" - RSI Chart",
                                                              Values = List<ObservablePoint>,
                                                              TooltipLabelFormatter = p => $"{ticker}, "+(new DateTime((long)p.SecondaryValue).ToString("MM/dd/yyyy hh:mm tt"))+$", RSI: {p.PrimaryValue:N2} "+" ",
                                                              Stroke = new LiveChartsCore.SkiaSharpView.Painting.SolidColorPaint(new SkiaSharp.SKColor(0, 0, 255)) { StrokeThickness = 1 },
                                                              Fill = null,
                                                              GeometrySize = 1
                                                         }
                                                     };
