To reproduce: -add RadChartView and use the following code: this.radChartView1.AreaType = ChartAreaType.Pie; PieSeries series = new PieSeries(); series.DataPoints.Add(new PieDataPoint(50, "Germany")); series.DataPoints.Add(new PieDataPoint(70, "United States")); series.DataPoints.Add(new PieDataPoint(40, "France")); series.DataPoints.Add(new PieDataPoint(25, "United Kingdom")); series.ShowLabels = true; this.radChartView1.Series.Add(series); Workaround: recreate the ChartDataPointElementController: this.radChartView1.AreaType = ChartAreaType.Pie; this.radChartView1.Controllers.RemoveAt(0); this.radChartView1.Controllers.Add(new ChartDataPointElementController()); PieSeries series = new PieSeries(); series.DataPoints.Add(new PieDataPoint(50, "Germany")); series.DataPoints.Add(new PieDataPoint(70, "United States")); series.DataPoints.Add(new PieDataPoint(40, "France")); series.DataPoints.Add(new PieDataPoint(25, "United Kingdom")); series.ShowLabels = true; this.radChartView1.Series.Add(series);

The Step Line chart type is similar to the Line chart type, but it does not use the shortest distance to connect two data points. Instead, this chart type uses vertical and horizontal lines to connect the data points in a series forming a step-like progression.

RadChartView - sometimes Property Builder of RadChartView is setting HorizontalAxis to be LinearAxis and to VerticalAxis to be DateTimeCategoricalAxis when you select "Linear & Date Time Categorical " which leads to incorrect work of PanZoom. Workaround: Use Smart Tag instead of Property Builder or swap the types of the axes in Design file.

To reproduce:
1.Add RadChartView
2.Set vertical axis to be LinearAxis
3.Add DataPoints with value with 14 or more digits.
4.Set FormatLabel = {0:C} or {0:F0}
5.Run project and will see that labels overlaps vertical axis.
Workaround:
Use custom format provider
this.radChartView1.Axes[1].LabelFormatProvider = new MyFormatProvider();

To reproduce:
Add a RadChartView and add some LineSeries and data points. Set the ShowTrackBall property to true. In some cases KeyNotFound exception occurs.
Workaround:
Use the following class:
public class MyController : ChartTrackballController
{
protected override string GetTrackballText(List<DataPointInfo> points)
{
StringBuilder result = new StringBuilder("<html>");
SortedDictionary<ChartSeries, List<DataPoint>> visiblePoints = new SortedDictionary<ChartSeries, List<DataPoint>>(new ChartSeriesComparer());
foreach (DataPointInfo pointInfo in points)
{
if (visiblePoints.ContainsKey(pointInfo.Series))
{
visiblePoints[pointInfo.Series].Add(pointInfo.DataPoint);
}
else
{
visiblePoints.Add(pointInfo.Series, new List<DataPoint>() { pointInfo.DataPoint });
}
}
int counter = 0;
foreach (ChartSeries series in visiblePoints.Keys)
{
for (int i = 0; i < visiblePoints[series].Count; i++)
{
Color pointColor = this.GetColorForDataPoint(series, visiblePoints[series][i]);
string color = string.Format("{0},{1},{2},{3}", pointColor.A, pointColor.R, pointColor.G, pointColor.B);
result.AppendFormat("<color={0}>{1}", color, this.GetPointText(visiblePoints[series][i]));
if (i < visiblePoints[series].Count)
{
result.Append(" ");
}
}
counter++;
if (counter < visiblePoints.Keys.Count)
{
result.Append("\n");
}
}
result.Append("</html>");
return result.ToString();
}
class ChartSeriesComparer : IComparer<ChartSeries>
{
public ChartSeriesComparer()
{
}
public int Compare(ChartSeries x, ChartSeries y)
{
if (!(x is IndicatorBase) && y is IndicatorBase)
{
return -1;
}
else if (x is IndicatorBase && !(y is IndicatorBase))
{
return 1;
}
return x.GetHashCode().CompareTo(y.GetHashCode());
}
}
}
Replace the old controller as follows:
for (int i = 0; i < this.radChartView1.Controllers.Count; i++)
{
if (this.radChartView1.Controllers[i] is ChartTrackballController)
{
this.radChartView1.Controllers[i] = new MyController();
break;
}
}
Note that the controller must be replaced before any data is added to the chart

If one removes the trackball controller while the trackball info element is visible it will remain on the chart. Steps to reproduce: 1. Add a chart to a form 2. Add series and data points 3. Subscribe for the chart MouseClick event 4. In the event handler change the value of the chart ShowTrackball property (from false to true or vice versa) Start the project and click several times on the chart. You will see that trackball info elements will remain on the chart.
