If no value is provided, the default styles will be used.
Gets or sets the name of the property that contains Y values for the series.
Gets or sets the name of the property that contains X values for the series.
Gets the ICollectionView object that contains the data for this series.
Gets or sets the array or ICollectionView object that contains the series data.
Gets or sets the series name.
The series name is displayed in the chart legend. Any series without a name does not appear in the legend.
Gets or sets the period of the moving average series. It should be set to integer value greater than 1.
Gets or sets the sample count for function calculation. The property doesn't apply for MovingAverage.
Gets or sets the shape of marker to use for each data point in the series. Applies to Scatter, LineSymbols, and SplineSymbols chart types.
Gets or sets the size(in pixels) of the symbols used to render this Series. Applies to Scatter, LineSymbols, and SplineSymbols chart types.
Gets or sets the series symbol style. Applies to Scatter, LineSymbols, and SplineSymbols chart types.
Gets or sets an enumerated value indicating whether and where the series appears.
approximate(x: number): number
Gets the approximate y value from the given x value.
The x value to be used for calculating the Y value.
drawLegendItem(engine: IRenderEngine, rect: Rect, index: number): void
Draw a legend item at the specified position.
The rendering engine to use.
The position of the legend item.
Index of legend item(for series with multiple legend items).
getDataRect(currentRect?: Rect, calculatedRect?: Rect): Rect
Returns series bounding rectangle in data coordinates.
If getDataRect() returns null, the limits are calculated automatically based on the data values.
The current rectangle of chart. This parameter is optional.
The calculated rectangle of chart. This parameter is optional.
getPlotElement(pointIndex: number): any
Gets the plot element that corresponds to the specified point index.
The index of the data point.
hitTest(pt: any, y?: number): HitTestInfo
Gets a HitTestInfo object with information about the specified point.
The point to investigate, in window coordinates.
The Y coordinate of the point (if the first parameter is a number).
legendItemLength(): number
Returns number of series items in the legend.
measureLegendItem(engine: IRenderEngine, index: number): Size
Measures height and width of the legend item.
The rendering engine to use.
Index of legend item(for series with multiple legend items).
onRendered(engine: IRenderEngine): void
Raises the rendered event.
The IRenderEngine object used to render the series.
onRendering(engine: IRenderEngine, index: number, count: number): boolean
Raises the rendering event.
The IRenderEngine object used to render the series.
The index of the series to render.
Total number of the series to render.
Represents a moving average trendline for FlexChart and FinancialChart. It is a calculation to analyze data points by creating a series of averages of different subsets of the full data set. You may define a different type on each MovingAverage object by setting the type property on the MovingAverage itself. The MovingAverage class has a period property that allows you to set the number of periods for computing the average value.
