In a multiple series scenario if one series gets removed, an internal axis flag is incorrectly reset resulting in the horizontal axis displaying only one label when SmartLabelsMode is used. One way to work-around this is to add an empty dummy series after removing a real series:

            this.chart1.Series.Remove(EmptyDummySeries);
            if (this.chart1.Series.Count > 0)
            {
                this.chart1.Series.RemoveAt(this.chart1.Series.Count - 1);
                if (this.chart1.Series.Count > 0)
                {
                    this.chart1.Series.Add(EmptyDummySeries);
                }
            }

I would like to be able to create a histogram where both the x and y axis are linear series and where I can specify the start and end position of each bin (not just one). Previously described workarounds include using StepLineSeries and bar series which cannot have two linear series. I cannot use a scatter plot series as they do not provide the step-wise look of the histogram.  Please add this support! 

Fix available in LIB Version 2016.2.606.

Add auto-range ability for the numeric axes that adjusts its range in accordance to the visible/zoomed data to show the data more clearly

If the annotation and its label are out of the viewport (the plot area) and then use the PanZoomBar to scroll to it, the label is not displayed. It appears after the chart layout is updated (ex: resize or zoom).

The SelectStyle() method of the DefaultVisualStyleSelector is never called

Will be available in R2 2016 Release.

Depending on the zoom level and height of chart, sometimes the first (bottom) label of the chart is not rendered when the vertical axis is a categorical one and the plot mode is BetweenTicks or OnTicksPadded. 

When you try to set the LabelDefinition property in style it is not applied.

As a workaround you can create an attached property to which you can apply the custom definition and set it to the LabelDefinition property of the annotation in its OnPropertyChangedCallback.

MovingAverageIndicator doesn't recalculate its data points when a new item is added in its ItemsSource at runtime

Workaround:
To update the data points of the indicator reset its Period property when a new item is added in the ItemsSource. For example:

// add new item
var indicator = chart.Indicators[0] as MovingAverageIndicator;
var period = indicator.Period;
indicator.Period = 0;
indicator.Period = period;

Add support for 3D Series Type in RadChartView.

A RadCartesianChart3D was introduced with R3 2016. You can use its BarSeries3D to easily achieve the Manhattan chart visualization.

If you change the axes of a series at runtime in the following order the axis won't be rendered as expected.
1. Set the series' VerticalAxis property to a new axis instance
2. Set the series' VerticalAxis property to another new axis instance
3. Set the series' VerticalAxis property to the axis' instance created in step 1

This is observed in a scenario with two chart series and only the axis of one of the series is drawn incorrect.

When step 3 is performed, the axis is drawn at incorrect position. Then if you resize, the axis will be repositioned but without any ticks or labels.

Available in LIB Version 2015.3.1123.

Workaround:
One way to work around this is to set the plot mode of the axis to OnTicksPadded. 

The position of non-positive values cannot be determined when using a logarithmic axis (due to the nature of the logarithmic axis, non-positive values are undefined). Currently the chart displays such points as if the value of the point is 1, which is not correct. The chart should not display these values at all.

Currently, RadChartView doesn't support ChartToolTipBehavior for series which are using BitmapRenderOptions or Direct2DRenderOptions. The tooltip doesn't display.

Make the StepLineSeries being able to plot a 'step' for a single point. Currently the StepLine series does not support drawing a single data point when it is in the beginning or the end of the ItemsSource. 

A NullReferenceException is thrown when the Strategy of the series is set
