Please add a feature for justifying the bar series chart so that bar data points can be plotted with a "Left", "Right", or "Center" justification to chart ticks.

An image to describe a "Right" vs "Center" bar justification is provided.

PlotArea occasionally stops refreshing in live data scenario with asynchronous updates (multithreading).

Available in 2014 Q3 release.

When the ItemsSource of a series is replaced with new collection, the labels of the old series are not cleared.

Fixed in LIB version: 2014.2.714

Add grid line style selector

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.

An InvalidCastException is thrown in the Fill/Background property binding in the series' DefaultVisualStyle when the RenderOptions is set to Bitmap or Direct2D.

ChartView: InvalidCastException is thrown when using series provider and the property that provides the series' Type is declared in an abstract class

The exception is reproduced only if the Visibility is initially bound to a property that returns Collapsed.

This can be reproduce with the chart indicators that derives from LineIndicatorBase. For example, MovingAverageIndicator or MomentumIndicator.

To resolve this you can bind the Opacity property instead of Visibility.

This is reproducible only when the chart's automation peers are used. For example, they are used by default when you use the chart on a touch screen. Or when an accessibility tool is used on the application with the chart.

You can work it around by disabling the auto peers (http://docs.telerik.com/devtools/wpf/common-ui-automation).

AutomationManager.AutomationMode = AutomationMode.Disabled;

The exception is reproducible when the chart contains series with RenderOptions=Direct2DRenderOptions.

The error message is:

HRESULT: [0x8876086A], Module: [SharpDX.Direct3D9], ApiCode: [D3DERR_NOTAVAILABLE/NotAvailable], Message: Unknown

Some of the data points plotted in the chart are not positioned as expected in a scenario with DateTimeContinuousAxis with SmartLabelsMode=SmartStep and PlotMode=OnTicksPadded or BetweenTicks.

DateTimeContinuousAxis produces too many labels when zoom in to the max and then zoomed out with double clicking the slider. The result is different when zooming out while dragging the slider and when double clicking it.
