Add a mechanism that allows the chart to process only the data within the viewport. This should improve the memory footprint and the performance of the chart in scenarios with big number of data points.
Introduce a way to set a geometry for the chart series' data points. Currently you cannot easily change the geometry of the default visual of PointSeries and LineSeries, for example. We can also introduce a default visual geometry selector.
Create 2-dimensional contour plot from unstructured 3-dimensional data. Means the points are randomly arranged in the XY plane. Attached file shows an example of what I would like to achieve. I think the contour plot Telerik does currently requires a structured grid, i.e. full grid of NxM points.
Currently, if the trackball position is outside the plot area boundaries, the element is not clipped and there is no mechanism that allows clipping it. Note: The trackball is the small ellipse that snaps to the data points.
Allow to track points that intercept vertical line from mouse position (as now) or points that intercept horizontal line from mouse position. So allow to choose TrackDirection = Horizontal/Vertical Thanks. marc.
Add mechanism for getting the layout slot of the axis
Ability to specify a cursor during a drag-to-pan operation. One way to work-around this is to use the attached property in the sample project attached here. This is the code needed to start using the solution: <telerik:RadCartesianChart local:ChartUtilities.PanCursor="Hand" />
When thousands of items are displayed, the tooltip and trackball behaviors may become slow, because of inefficient searching for the closest datapoints. Performance can be sped up by implementing a custom search and manually creating a ChartDataContext via the GetDataContext method.
