Func< int, T, object >	Label `[get, set]`
	A function used to determine the text of the labels to draw. The arguments for this function should be a `int` representing the index of the data point and a T representing the coordinates of the data point. This function should return either an IEnumerable<T> of FormattedText objects, which will be used as-is, or any other kind of object, which will be converted to a `string` to be used in the label.

Func< int, T, double >	Rotation = (i, d) => 0 `[get, set]`
	A function used to determine the orientation of the labels with respect to the horizontal. The arguments for this function should be a `int` representing the index of the data point and a T representing the coordinates of the data point. This function should return a `double` representing the angle with respect to the horizontal at which the label should be drawn. More...

Func< int, T, Point >	Margin = (i, d) => new Point() `[get, set]`
	A function used to determine the position of the labels with respect to the data points. The arguments for this function should be a `int` representing the index of the data point and a T representing the coordinates of the data point. This function should return a Point defining the amount of space between the data point and the label, in plot coordinates. More...

◆ Baseline

TextBaselines VectSharp.Plots.DataLabels< T >.Baseline = TextBaselines.Middle

getset

The baseline for the labels.

Definition at line 417 of file DataPoints.cs.

◆ CoordinateSystem

ICoordinateSystem<T> VectSharp.Plots.DataLabels< T >.CoordinateSystem

getset

◆ Data

IEnumerable<T> VectSharp.Plots.DataLabels< T >.Data

getset

The data points at which the labels will be drawn.

Definition at line 341 of file DataPoints.cs.

◆ Label

Func<int, T, object> VectSharp.Plots.DataLabels< T >.Label

getset

A function used to determine the text of the labels to draw. The arguments for this function should be a int representing the index of the data point and a T representing the coordinates of the data point. This function should return either an IEnumerable<T> of FormattedText objects, which will be used as-is, or any other kind of object, which will be converted to a string to be used in the label.

◆ Margin

Func<int, T, Point> VectSharp.Plots.DataLabels< T >.Margin = (i, d) => new Point()

getset

A function used to determine the position of the labels with respect to the data points. The arguments for this function should be a int representing the index of the data point and a T representing the coordinates of the data point. This function should return a Point defining the amount of space between the data point and the label, in plot coordinates.

Definition at line 412 of file DataPoints.cs.

Definition at line 433 of file DataPoints.cs.

◆ Rotation

Func<int, T, double> VectSharp.Plots.DataLabels< T >.Rotation = (i, d) => 0

getset

A function used to determine the orientation of the labels with respect to the horizontal. The arguments for this function should be a int representing the index of the data point and a T representing the coordinates of the data point.

Definition at line 405 of file DataPoints.cs.

◆ Tag

string VectSharp.Plots.DataLabels< T >.Tag

getset

A tag to identify the labels in the plot.
