Currently plot band and marked zone annotations are not snapped to the ticks when the PlotMode of a CategoricalAxis is BetweenTicks. Instead the annotation starts from the middle of the slot, and from the middle of the bar (when using BarSeries). 

Introduce a way to snap plot band annotations and marked zone annotations to the ticks instead of the middle of the slot of the categorical axis.

ChartDataSource control should perform the sampling operation asynchronously in a background thread so that it is not blocking the UI thread.

Allow for the Polar chart to have multiple polar axes so that a user can easily understand what value does a data point have. For example a polar chart with four axes (with the same range) and an axis in each quadrant.

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;

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);
                }
            }

The data points are not rendered when the series' axis is set at runtime through a DataTrigger in the series' style. 

Note: The data points are rendered when the chart is resized or zoomed.

Workaround:
Change the resource type in the DataTrigger that changes the axis - instead of DynamicResource, use StaticResource. 

<telerik:CategoricalSeriesDescriptor.Style>
    <Style TargetType="telerik:LineSeries">
        <Style.Triggers>
            <DataTrigger Binding="{Binding Path=Axis}" Value="Left">
                <Setter Property="VerticalAxis" Value="{StaticResource AxisLeft}"/>
            </DataTrigger>
            <DataTrigger Binding="{Binding Path=Axis}" Value="Right">
                <Setter Property="VerticalAxis" Value="{StaticResource AxisRight}"/>
            </DataTrigger>
        </Style.Triggers>
    </Style>
</telerik:CategoricalSeriesDescriptor.Style>

Workaround: Bind the UpStroke and DownStroke properties of the Candlestick via custom style (which is set to the DefaultVisualStyle property) to properties from the model. Then in the setter of the Close property, can set different color depending on whether the Close is less than Open property.

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!

There are scenarios where the actual minimum and maximum of the axis are of high importance but they are not displayed (due to TickOrigin). For instance if the axis range is (-1, 11) and TickOrigin is "0", the labels will be (0, 2, 4...) and "-1" and "11" will not be displayed.

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

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.

Implement an indication for negative areas in a single AreaSeries/RangeSeries. For example the negative areas to be drawn in one color and the positive areas in another.

For more information on the visual representation you can take a look at the following blog post:

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.
