機能

• UltraDataChart
  • Trendline Layer - The TrendlineLayer is a new series type that allows you to apply a single trend line per trend line layer to a particular series. This allows the usage of multiple trend lines on a single series since you can have multiple TrendlineLayer series types in the chart.
  • Data Legend and DataTooltip LayoutMode - The UltraDataLegend and DataToolTipLayer elements now expose a LayoutMode property that you can use to layout the legend in either a table or vertical structure.
  • Data Annotation Band Layer (Beta) - The DataAnnotationBandLayer is a new annotation layer that displays over the series.
  • Data Annotation Line Layer (Beta) - The DataAnnotationLineLayer is a new annotation layer that displays over the series.
  • Data Annotation Rect Layer (Beta) - The DataAnnotationRectLayer is a new annotation layer that displays over the series.
  • Data Annotation Slice Layer (Beta) - The DataAnnotationSliceLayer is a new annotation layer that displays over the series.
  • Data Annotation Strip Layer (Beta) - The DataAnnotationStripLayer is a new annotation layer that displays over the series.
  • Drag Selection (Beta) - There is a new enumeration for the DefaultInteraction property on the chart named DragSelect. This will use the preview Rect of the chart to select points of a series.
  • Overlay Text (Beta)- The following series types now support overlaying text for additional annotation in the chart by using the new OverlayText property: ValueLayer and ValueOverlay. In addition to the series types mentioned, the new data annotation layers listed above also support this feature. You can configure how this overlay text appears in aspects such as angle, color, background, padding, margin, font, etc. by using the many OverlayText-prefixed properties. For example, OverlayTextBrush will configure the color.
• UltraDataPieChart
  • The chart now exposes a GetOthersContext() method. This will return the contents of the others slice.
