public void InitializeGenericPlotLines<T>(IEnumerable<T> data, Func<T, object>? getYAxis, Func<T, object> createPlotUI, bool isXAxisDateTime)

View source

Summary: Initializes and configures up to 16 plot lines in the chart using the provided data and UI creation logic, assigning each plot line to the appropriate Y-axis and setting up the X-axis as either date/time or numeric points.

Type parameters

Name	Description
`T`	The type of the data items to be plotted. Each item represents a single plot line.

Parameters

Name	Type	Description
`data`	IEnumerable	The collection of data items to be plotted. Cannot be null. A maximum of 16 items will be processed.
`getYAxis`	Func?	A function that determines the Y-axis assignment for each data item. Returns either an integer index or an observable of integer indices. Cannot be null.
`createPlotUI`	Func	A function that creates the plot line UI element for each data item. Cannot be null.
`isXAxisDateTime`	bool	Specifies whether the X-axis should be configured for date/time values (`true`) or numeric points (`false`).

Remarks

If more than 16 data items are provided, only the first 16 will be plotted. Each plot line is assigned to a Y-axis based on the value returned by getYAxis. If an observable is returned, the plot line will update its Y-axis assignment dynamically as the observable emits new values. The method clears existing chart content before initializing new plot lines.

Exceptions

Type	Condition
System.ArgumentNullException	Thrown if `data`, `getYAxis`, or `createPlotUI` is null, or if a plot UI element cannot be created for a data item.
System.IndexOutOfRangeException	Thrown if the Y-axis index provided by `getYAxis` is less than zero or greater than or equal to the number of available Y-axes.
