3D Charts will be a nice addition to the WinForms suite

Add vertical cursors for Line series that stay in place unless the user drags them. Each cursor should select the data points that covers. The cursor should allow setting its position programmatically.

Steps to reproduce:
1. Add a chart to a form.
2. Add any cartesian series
3. Set the LabelFitMode of the horizontal axis to Rotate.

You will see that labels have incorrect layout.

IMPROVE. RadChartView - one should be able to access the tooltip instance in order to customize it (change font, delay, etc)
Completed
Last Updated: 07 Dec 2016 08:41 by ADMIN
To reproduce:
- Add at least two series and zoom the chart so the point from one of the series are visible only
- Move the TrackBall
- The Track ball is not shown for some of the points.

Steps to reproduce.

1. Add a chart view to a form.
2. Create a series and add several data points. For categories use double values in the range 10 - 20
3. Create a second series and this time for categories use double values in the same range without duplication.
4. Assign one linear and one categorical axis to the series and add them to the char view.
5. Run the project and you will see that the categories from the second series are next to those from the first series, while they should be combined according their values.

I'm using version 2012.3.1310.40
I use ChartView to create a pie chart with the following data
Assets          2248550.22
Income             19748.67
Equity           2228253.95
Liability                 547.60

So, when the chart displays, the Percentage is set as follows:
Assets       50%
Income        0%
Equity         50%
Liability        0%

I notice when the percentage is 0% for any data, the pie chart shows "0%" near the chart title (please see attachment).  Or if the calculated data returns 0, it doesn't show any percentage on the chart, but it will shows "NaN" near the title as well. (please see attachment).

To reproduce:
public Form1()
{
    InitializeComponent();

    ScatterSeries series = new ScatterSeries();
    series.DataPoints.Add(new ScatterDataPoint(5, 5));
    series.DataPoints.Add(new ScatterDataPoint(4, 2));
    series.DataPoints.Add(new ScatterDataPoint(-1, 3));
    series.DataPoints.Add(new ScatterDataPoint(8, 4));

    radChartView1.Series.Add(series);

    LinearAxis horizontalAxis = radChartView1.Axes.Get<LinearAxis>(0);
    horizontalAxis.Minimum = -10;
    horizontalAxis.Maximum = 10;
}
private void radButton1_Click(object sender, EventArgs e)
{
    LinearAxis horizontalAxis = radChartView1.Axes.Get<LinearAxis>(0);
    horizontalAxis.DesiredTickCount = 20;
}

    BarSeries barSeries = new BarSeries("Performance", "RepresentativeName");
    barSeries.Name = "Q1";
    barSeries.DataPoints.Add(new CategoricalDataPoint(177, "Harley"));

    barSeries.DataPoints.Add(new CategoricalDataPoint(118, "Marshall"));

Note: similar to the axis, the series should also have ClipLabels property which will control whether the labels will be clipped or not.

How to reproduce: zoom and pan along the chart
public Form1()
{
    InitializeComponent();

    this.radChartView1.CreateRenderer += radChartView1_CreateRenderer;
    this.radChartView1.ShowPanZoom = true;

    BarSeries barSeries = new BarSeries();
    Random rand = new Random();
    for (int i = 1; i < 10; i++)
    {
        barSeries.DataPoints.Add(new CategoricalDataPoint(rand.Next(100), i));
    }

    barSeries.ShowLabels = true;
    this.radChartView1.Series.Add(barSeries);
}

Workaround:
 public partial class Form1 : Form
 {
     public Form1()
     {
         InitializeComponent();

         this.radChartView1.CreateRenderer += radChartView1_CreateRenderer;

         Random rand = new Random();
         for (int i = 1; i < 10; i++)
         {
             barSeries.DataPoints.Add(new CategoricalDataPoint(rand.Next(100), i));
         }

         barSeries.ShowLabels = true;
         this.radChartView1.Series.Add(barSeries);
     }

     private void radChartView1_CreateRenderer(object sender, ChartViewCreateRendererEventArgs e)
     {
         e.Renderer = new CustomCartesianRenderer(e.Area as CartesianArea);
     }
 }

 public class CustomCartesianRenderer : CartesianRenderer
 {
     public CustomCartesianRenderer(CartesianArea area)
         : base(area)
     { }
     protected override void Initialize()
     {
         base.Initialize();

         for (int i = 0; i < this.DrawParts.Count; i++)
         {
             BarLabelElementDrawPart labelPart = this.DrawParts[i] as BarLabelElementDrawPart;
             if (labelPart != null)
             {
                 this.DrawParts[i] = new CustomLabelElementDrawPart((BarSeries)labelPart.Element, this);
             }
         }
     }
 }

 public class CustomLabelElementDrawPart : BarLabelElementDrawPart
 {
     public CustomLabelElementDrawPart(ChartSeries owner, IChartRenderer renderer)
         : base(owner, renderer)
     { }
     
     public override void Draw()
     {
         Graphics graphics = this.Renderer.Surface as Graphics;
         CartesianSeries cartesianSeries = this.Element as CartesianSeries;
         if (cartesianSeries != null)
         {
             CartesianArea area = (CartesianArea)cartesianSeries.GetType().GetField("area", BindingFlags.Instance | BindingFlags.NonPublic).GetValue(cartesianSeries);
             RectangleF clipRect = (RectangleF)area.GetType().GetMethod("GetCartesianClipRect", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(area, new object[] { });//.GetCartesianClipRect();
             graphics.SetClip(clipRect);
         }

         base.Draw();

         graphics.ResetClip();
     }

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