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.

RadChartView - DateTimeContinueAxis ignores the MaximumTicks property with some specific data points. 

Steps to reproduce:
Use the following points:
            points.Add(new CategoricalDataPoint(r.Next(0, 100), new DateTime(2007, 7, 24)));
            points.Add(new CategoricalDataPoint(r.Next(0, 100), new DateTime(2007, 10, 30)));
            points.Add(new CategoricalDataPoint(r.Next(0, 100), new DateTime(2008, 4, 29)));
            points.Add(new CategoricalDataPoint(r.Next(0, 100), new DateTime(2008, 10, 27)));
            points.Add(new CategoricalDataPoint(r.Next(0, 100), new DateTime(2009, 4, 1)));
            points.Add(new CategoricalDataPoint(r.Next(0, 100), new DateTime(2010, 6, 28)));

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

It would be very helpful if you either added ScaleBreaks (as in the deprecated RadChart control - http://www.telerik.com/help/winforms/chart-features-scale-breaks.html) or provided an alternative way. I use them a great deal with bar charts and logarithmic scales are not optimal.

Steps to reproduce:
1. Add a pie series to a chart 
2. add three data points with values 19,20 and 61
3. Set the series LabelsOffsetFromCenter property to 0.2d
4. Run the project and start reducing the size of the chart. At some point you will see that the position of the label 20% will be incorrect.

Second scenario:
Add a pie chart and populate it with PieDataPoints, one of which is with value 0:

        Me.RadChartView1.AreaType = ChartAreaType.Pie
        Dim series As 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.DataPoints.Add(New PieDataPoint(0, "Italy"))
        series.ShowLabels = True
        Me.RadChartView1.Series.Add(series)

If one sets the LabelFormat property of LinearAxis it will not be respected in most cases.
Steps to reproduce:
1. Add a LineSeries to a chart
2. Set the VerticalAxis.LabelFormat to "{0:F2}"
3. Run the project
You will see that the labels are not formatted.
