Release R3 2019 (LIB 2019.2.708)
The same issue can be observed in a DPI-aware application on higher scaling
Workaround: set the RadControl.EnableDpiScaling property to false

public partial class Form1 : Form
{
    public Form1()
    {
        RadControl.EnableDpiScaling = false;

        InitializeComponent();

        LineSeries lineSeries = new LineSeries();
        lineSeries.DataPoints.Add(new CategoricalDataPoint(20, "Jan"));
        lineSeries.DataPoints.Add(new CategoricalDataPoint(22, "Apr"));
        lineSeries.DataPoints.Add(new CategoricalDataPoint(12, "Jul"));
        lineSeries.DataPoints.Add(new CategoricalDataPoint(19, "Oct"));
        this.radChartView1.Series.Add(lineSeries);

        LineSeries lineSeries2 = new LineSeries();
        lineSeries2.DataPoints.Add(new CategoricalDataPoint(18, "Jan"));
        lineSeries2.DataPoints.Add(new CategoricalDataPoint(15, "Apr"));
        lineSeries2.DataPoints.Add(new CategoricalDataPoint(17, "Jul"));
        lineSeries2.DataPoints.Add(new CategoricalDataPoint(22, "Oct"));
        this.radChartView1.Series.Add(lineSeries2);
        
        LassoZoomController lassoZoomController = new LassoZoomController();
        radChartView1.Controllers.Add(lassoZoomController);
    }

    private void radButton1_Click(object sender, EventArgs e)
    {
        this.radChartView1.ExportToImage(@"..\..\image.png", this.radChartView1.Size);
    }
}

The new controller should allow lasso selection of data points without zooming the view port.

It would be great to be able to generate Box Plot graphics, both in the RadCharView control and in the Report.

When setting the border color of the axis the labels are showing a border with the same color. The color is inherited from the axis element. One should be able to easily disable this, or it should not happen.

How to reproduce: 
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
    LineSeries lineSeries;

    public RadForm1()
    {
        InitializeComponent();

        this.lineSeries = new LineSeries();

        this.lineSeries.DataPoints.Add(new CategoricalDataPoint(20, "Jan"));
        this.lineSeries.DataPoints.Add(new CategoricalDataPoint(22, "Apr"));
        this.lineSeries.DataPoints.Add(new CategoricalDataPoint(25, "Jul"));
        this.lineSeries.DataPoints.Add(new CategoricalDataPoint(19, "Oct"));

        this.radChartView1.Series.Add(this.lineSeries);

        this.lineSeries.HorizontalAxis.BorderColor = Color.Green;
        this.lineSeries.VerticalAxis.BorderColor = Color.Blue;
    }
}

Workaround: iterate each of the axis labels and set their border color to Transparent
public partial class RadForm1 : Telerik.WinControls.UI.RadForm
{
    LineSeries lineSeries;

    public RadForm1()
    {
        InitializeComponent();

        this.lineSeries = new LineSeries();

        this.lineSeries.DataPoints.Add(new CategoricalDataPoint(20, "Jan"));
        this.lineSeries.DataPoints.Add(new CategoricalDataPoint(22, "Apr"));
        this.lineSeries.DataPoints.Add(new CategoricalDataPoint(25, "Jul"));
        this.lineSeries.DataPoints.Add(new CategoricalDataPoint(19, "Oct"));

        this.radChartView1.Series.Add(this.lineSeries);

        this.lineSeries.HorizontalAxis.BorderColor = Color.Green;
        this.lineSeries.VerticalAxis.BorderColor = Color.Blue;
    }

    protected override void OnShown(EventArgs e)
    {
        base.OnShown(e);

        foreach (var item in this.lineSeries.VerticalAxis.Children)
        {
            AxisLabelElement label = item as AxisLabelElement;
            if (label != null)
            {
                label.BorderColor = Color.Transparent;
            }
        }

        foreach (var item in this.lineSeries.HorizontalAxis.Children)
        {
            AxisLabelElement label = item as AxisLabelElement;
            if (label != null)
            {
                label.BorderColor = Color.Transparent;
            }
        }
    }
}

The new functionality should allow a display similar to the one in the WPF pie series:

Note: when you apply a palette the series doesn't have hover and selection indication.

Why exists the Crosshair feature only for the WPF version of the RadChartView and not for the WinForms implementation?

Is there a plan to release that feature for WinForms too?

Thx in advance
Uli

To reproduce:

AreaSeries areaSeries = new AreaSeries();
areaSeries.DataPoints.Add(new CategoricalDataPoint(13, "Jan"));
areaSeries.DataPoints.Add(new CategoricalDataPoint(20, "Apr"));
areaSeries.DataPoints.Add(new CategoricalDataPoint(15, "Jul"));
areaSeries.DataPoints.Add(new CategoricalDataPoint(16, "Oct"));
this.radChartView1.Series.Add(areaSeries); 

areaSeries.BackColor = Color.Transparent;

areaSeries.CombineMode = ChartSeriesCombineMode.Stack;
AreaSeries areaSeries2 = new AreaSeries();
areaSeries2.DataPoints.Add(new CategoricalDataPoint(15, "Jan"));
areaSeries2.DataPoints.Add(new CategoricalDataPoint(25, "Apr"));
areaSeries2.DataPoints.Add(new CategoricalDataPoint(27, "Jul"));
areaSeries2.DataPoints.Add(new CategoricalDataPoint(18, "Oct"));
this.radChartView1.Series.Add(areaSeries2);
areaSeries2.CombineMode = ChartSeriesCombineMode.Stack;

 The area underneath the transparent one shouldn't be displayed in this case because they are stacked.  There is no area underneath the bottom layer to display. They are each STACKED on top of each other, they should not be layered in front of each other.
