How can I hide the point in the lineSeries with the large data,and then zoom in by mousewheel,the point can be show in the lineSeries,when zoom out again,the point can be hide. Because with large data in a view,if show the point, the lineSeries's performance is poor,and the details area is not necessary,only when zoom in,we hope to show the point.
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.
On a desktop device the tooltip is shown when the mouse enters the data point's visual element. On touch device the tooltip should be displayed when you tap (or tap and hold) on the visual element. Currently, this doesn't work. To work this around you can implement custom tooltip behavior using RadToolTip and TouchManager. https://docs.telerik.com/devtools/wpf/controls/radtooltip/overview https://docs.telerik.com/devtools/wpf/controls/touchmanager/overview
During Series animation, the stroke of the AreaSeries (area, splinearea, scatterarea, steparea) is not animated.
Gaps appear between the bars in the stacks when the series are populated with negative and positive values. Check the attached picture. If you have a scenario with mixed values (positive and negative) use RangeBarSeries instead of BarSeries.
Add support for chart series animations.
This reproduces when the axis' SmartLabelMode is enabled. For example, set to SmartStep. See the attached video. As a workaround you can disable the smart label mode and manually calculate the range when zooming. You can use its Minimum, Maximum, MajorStep and MajorStepUnit properties.
The exception is reproducible when you are using SplineSeries with DateTimeContinuousAxis. You need to add data points to the chart with a gap between the dates.
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.
An InvalidCastException is thrown in the Fill/Background property binding in the series' DefaultVisualStyle when the RenderOptions is set to Bitmap or Direct2D.
Add the option for having separate PanZoomBars for each axis, so the user can scroll/zoom each axis independently from the other axes.
Expose RadFunnelChart and RadFunnelSeries for displaying funnel-like segments. They are usually used for visualizing stages in sales / marketing processes. Available in R3 2017 Official Release Version. Check what's new in R3 2017 here: http://www.telerik.com/support/whats-new/wpf/release-history/ui-for-wpf-r3-2017
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;
When the points in a series consist of values including 0, DivideByZeroException is thrown. The exception is thrown while measuring the chart - the tick step is set to 0 and the index of the tick on the axis cannot be calculated. Workaround: Set the Minimum and Maximum properties of the Axis. Available in LIB version: 2017.2.605
