When one adds data points with negative and positive values, the negative ones should go below the 0, for example, with the following data: AreaSeries areaSeries = new AreaSeries(); areaSeries.DataPoints.Add(new CategoricalDataPoint(5, "Jan")); areaSeries.DataPoints.Add(new CategoricalDataPoint(-10, "Apr")); Resolution: To use the functionality one should set the StartPositionAxis and StartPositionValue properties of an axis. The first property is the axis along which the current axis will be aligned. The second is the value where the current axis should be positioned. Here is a sample code: AreaSeries areaSeries = new AreaSeries(); areaSeries.DataPoints.Add(new CategoricalDataPoint(13, "Jan")); areaSeries.DataPoints.Add(new CategoricalDataPoint(20, "Apr")); areaSeries.DataPoints.Add(new CategoricalDataPoint(-15, "Jul")); areaSeries.DataPoints.Add(new CategoricalDataPoint(16, "Oct")); this.radChartView1.Series.Add(areaSeries); areaSeries.HorizontalAxis.StartPositionAxis = areaSeries.VerticalAxis; areaSeries.HorizontalAxis.StartPositionValue = 0;
We should add a way for users to bind a property in the data source that will be used as a legend title for pie data points. Resolution: Set the LegendTitleMember property to bind legend title of PieSeries.
Currently, ScatterSeries are able to use NumericAxes only. A good improvement will be to allow using DateTimeContinuousAxes as well.
The lasso controller should zoom vertically as well.
Add vertical cursors for Line series that stay in place unless the user drags them. Each cursor should select the data points that covers. The cursor should allow setting its position programmatically.
RadChartView - Palette of the Series should be with higher priority than Area.View.Palette.
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.
Add Scatter Line Series Support to RadChartView
IMPROVE. RadChartView - one should be able to access the tooltip instance in order to customize it (change font, delay, etc)
