Show 14 items

Name	Description
Value	Indicates the value of a series point where the series point contains only one value.
Value_1	Indicates the First value of a series point, where the series view belongs to the Side-by-Side Range Bar, Overlapped Range Bar or Gantt view types.
Value_2	Indicates the Second value of a series point, where the series view belongs to the Side-by-Side Range Bar, Overlapped Range Bar or Gantt view types.
Low	Indicates the Low value of a series point, where the series view belongs to the Financial view type.
High	Indicates the High value of a series point, where the series view belongs to the Financial view type.
Open	Indicates the Open value of a series point, where the series view belongs to the Financial view type.
Close	Indicates the Close value of a series point, where the series view belongs to the Financial view type.
Weight	Indicates the weight value of a series point where a series view is a bubble view.
BoxPlotMin	Indicates the Min value of a series point, where the series view belongs to the Box Plot view type.
BoxPlotQuartile_1	Indicates the First Quartile value of a series point, where the series view belongs to the Box Plot view type.
BoxPlotMedian	Indicates the Median value of a series point, where the series view belongs to the Box Plot view type.
BoxPlotQuartile_3	Indicates the Third Quartile value of a series point, where the series view belongs to the Box Plot view type.
BoxPlotMax	Indicates the Max value of a series point, where the series view belongs to the Box Plot view type.
BoxPlotMean	Indicates the Mean value of a series point, where the series view belongs to the Box Plot view type.

Remarks

Any FinancialIndicator needs two points (FinancialIndicator.Point1 and FinancialIndicator.Point2) to be specified for it. And, each point should have a pair of arguments and values defined.

A point’s argument is defined via its FinancialIndicatorPoint.Argument property. And, the value is obtained from the series, in whose XYDiagram2DSeriesViewBase.Indicators storage the current FinancialIndicator resides.

If this series view requires more than one value to be defined for its data points (as in Stock and Candle Stick series), the required value level is specified via the ValueLevel property.

Example

This example demonstrates how to create a Fibonacci Indicator of a certain kind (Arcs, Fans or Retracements), and add it to a financial series.

To do this, create an instance of the FibonacciIndicator class, and specify its FibonacciIndicator.Kind property. Then, add this indicator to the series collection of indicators, returned by the XYDiagram2DSeriesViewBase.Indicators property.
