When there is defined a ChartPanAndZoomBehavior and the axes of the chart are switched at run-time, the orientation of the PanZoomBar elements it is not changed.

Workaround:
Get the PanZoomBar element and set its Orientation property.

private void TrySetOrientation(CartesianAxis axis, Orientation orientation)
{
    var panZoomBar = Telerik.Windows.Controls.ChildrenOfTypeExtensions.FindChildByType<PanZoomBar>(axis);
    if (panZoomBar != null)
    {
        panZoomBar.Orientation = orientation;
    }
}

private void SwapAxes()
{           
    // Swapping code here

    this.Dispatcher.BeginInvoke((Action)(() =>
    {
        this.TrySetOrientation(this.chart.HorizontalAxis, Orientation.Horizontal);
        this.TrySetOrientation(this.chart.VerticalAxis, Orientation.Vertical);
    }));
}

This can easily be resolved by using a Dispatcher.BeginInvoke to delay the adding of the element. 

The fix is available in LIB Version: 2014.3.1402.

Create  a chartview with a linear axis, set minvalue to 2014-11-21, max = 2014-11-24, create a series with only one datapoint with a date=2014-11-23.
The barchart graph will show a nice bar, but the X-axis will show you 2014-11-21, although the datapoint is for 2014-11-23!

Workaround:
The issue is caused by the MajorTickInterval property, so one way to go is to remove this setting and use the LabelInterval instead. This will plot more ticks than before, but should eliminate the label clip. If the number of ticks bothers you, you can set the MajorTickLength property of the axis to 0 (so that the ticks are not visible) and use a LabelTemplate in which you will include a label and a tick. 

Another, simpler, work-around is to set a right margin of the chart and set the ClipToBounds property of the chart to false.

A NullReferenceException is thrown when the Visibility of a CartesianCustomAnnotation  is initally set to Collapsed in XAML

The StrokeDashArray property is no applied when you set it on the Path element in the StrokeShapeStyle of a line series

A design time exception may be thrown in certain scenarios.

Missing annotation when the chart is placed inside TabControl and its PanZoomBars are collapsed through an implicit style. The annotation is displayed after resize or any other action that triggers redrawing of the control.

As a side note, this behavior occurs only if there is no pan and zoom behavior added in the Behaviors collection of the chart.

If you set the PolarAxis.Maximum property to value which is equal to or less than the smallest value of a series, a DevideByZero exception is thrown.

When the ItemsSource of a series is replaced with new collection, the labels of the old series are not cleared.

Fixed in LIB version: 2014.2.714

Available in 2014 Q3 release.

In a chart that displays more than one series, it would great to be able to turn on/off the trackball feature on a per-series basis. (Currently, suppressing the display of data for a given series doesn't prevent the trackball from snapping to points on that series - a weird experience for the user.

When the LabelTemplate property of the chart's axis is changed at runtime the labels are not resized and they overlap the plot area if they are too long.

Fixed in 2014.2.0630 LIB

NullReferenceException on updating data when mouse is over chart's area and trackballinfo is visible. 

To workaround this, remove the TrackBallBehavior when data is updated and add it again on MouseMove.

Offset appears when chart with no margins and paddings is exported.

All labels of the LogratihmicAxis display 'zero' in scenarios with small values  (for example: 0.000000000116 or 2.3E-10)
