Chart: More graceful handling of negative values when using logarithmic Y Axis.

First / last series item labels get clipped if they are large enough in some scenarios.

REASON FOR DECLINATION
This is supported by the new RadChartView (use the ClipToPlotArea property of the series or use a smart labels strategy).

The RadChart for Silverlight doesn't show the top value of YAxis when Step = 0.2.

When you set SeriesDefinition.SeriesStyle, you need to Rebind() in order to have the chart updated.

Keep the underlying data item for sampling functions like First, Last, Min and Max.

Chart: Provide event for chart item mouse up.

Chart: Extend XAxis -- allow arbitrary start value with ticks, placed on round values. Ex. MinValue = 127, MaxValue = 200, Step = 10 -> the ticks should be placed at 130, 140, 150, etc.

REASON FOR DECLINATION
This is supported out-of-the-box by the new RadChartView (axes have a TickOrigin property).

More geometries need to be available as marked zones. Additional y axes support also is necessary.

Chart: Allow user styles for interactivity features.

The user wants the Y axis appear in the right.

REASON FOR DECLINATION
This is supported out-of-the-box by the new RadChartView.

RadChart should support 3D Surface Series Type.

This feature is now available as part of the ChartView control since R3 2016 Official release. Refer to the link below for more information.

Microsoft Excel has an "autorange" feature for 1) y-axis min, 2) y-axis max, 3) major unit and 4) minor unit, all working independently of each other while Telerik RadChart AutoRange sets all 4 of these properties collectively, or sets none at all if autor

Stick / CandleStick series types should support item labels for Low, High, etc.

REASON FOR DECLINATION
This is supported out-of-the-box by the new RadChartView (use the LabelDefinitions property of the series).

The developer should be able to change the axis origin location in order to enable scenarios like this one:

- Essentially you have a list of negative numbers: 0, -10, -24, -35 and so on.
- If you want to show them as positive numbers (pointing upwards), y

Allow for smooth real time chart panning/scrolling.

REASON FOR DECLINATION
This is supported out-of-the-box by the new RadChartView.

Marked Zones and Custom Gridlines need to be separated in different layers.

Separate the style of the AxisStyles.GridLineStyle into MajorGridLineStyle and MinorGridLineStyle

REASON FOR DECLINATION
This is supported out-of-the-box by the new RadChartView.

Add click event for axis items.

REASON FOR DECLINATION
This is supported out-of-the-box by the new RadChartView (axes have a LabelTemplate property, use it to customize appearance and handle click).

Zooming works incorrectly when using AutoRange=true and CollectionIndex. The problem is also observed when dataitems in different series have independent XValues.

Labels for 0-value data points do not get alternative positions.
