Syntax

[Serializable]
public class ErrorBarItem : CurveItem, ICloneable, ISerializable

Remarks

The ErrorBarItem type is intended for displaying confidence intervals, candlesticks, stock High-Low charts, etc. It is technically not a bar, since it is drawn as a vertical or horizontal line. The default symbol at each end of the "bar" is HDash, which creates an "I-Beam". For horizontal bars (Y or Y2), you will need to change the symbol to VDash to get horizontal "I-Beams". Since the horizontal segments are actually symbols, their widths are controlled by the symbol size in Symbol, specified in points (1/72nd inch). The position of each "I-Beam" is set according to the PointPair values. The independent axis is assigned with Base, and is a BarBase enum type.

Constructors

ErrorBarItem(SerializationInfo, StreamingContext)

Constructor for deserializing objects

Declaration

protected ErrorBarItem(SerializationInfo info, StreamingContext context)

Parameters

Type	Name	Description
SerializationInfo	info	A SerializationInfo instance that defines the serialized data
StreamingContext	context	A StreamingContext instance that contains the serialized data

ErrorBarItem(String)

Create a new ErrorBarItem, specifying only the legend label.

Declaration

public ErrorBarItem(string label)

Parameters

Type	Name	Description
String	label	The label that will appear in the legend.

ErrorBarItem(String, Double[], Double[], Double[], Color)

Create a new ErrorBarItem using the specified properties.

Declaration

public ErrorBarItem(string label, double[] x, double[] y, double[] lowValue, Color color)

Parameters

Type	Name	Description
String	label	The label that will appear in the legend.
Double[]	x	An array of double precision values that define the X axis values for this curve
Double[]	y	An array of double precision values that define the Y axis values for this curve
Double[]	lowValue	An array of double precision values that define the lower dependent values for this curve
Color	color	A Color value that will be applied to the Line properties.

ErrorBarItem(String, IPointList, Color)

Create a new ErrorBarItem using the specified properties.

Declaration

public ErrorBarItem(string label, IPointList points, Color color)

Parameters

Type	Name	Description
String	label	The label that will appear in the legend.
IPointList	points	A IPointList of double precision values that define the X, Y and lower dependent values for this curve
Color	color	A Color value that will be applied to the Line properties.

ErrorBarItem(ErrorBarItem)

The Copy Constructor

Declaration

public ErrorBarItem(ErrorBarItem rhs)

Parameters

Type	Name	Description
ErrorBarItem	rhs	The ErrorBarItem object from which to copy

Fields

schema2

Current schema value that defines the version of the serialized file

Declaration

public const int schema2 = 10

Field Value

Type	Description
Int32

Properties

Bar

Gets a reference to the ErrorBar class defined for this ErrorBarItem.

Declaration

public ErrorBar Bar { get; }

Property Value

Type	Description
ErrorBar

Methods

Clone()

Typesafe, deep-copy clone method.

Declaration

public ErrorBarItem Clone()

Returns

Type	Description
ErrorBarItem	A new, independent copy of this class

Draw(Graphics, GraphPane, Int32, Single)

Do all rendering associated with this ErrorBarItem to the specified Graphics device. This method is normally only called by the Draw method of the parent CurveList collection object.

Declaration

public override void Draw(Graphics g, GraphPane pane, int pos, float scaleFactor)

Parameters

Type	Name	Description
Graphics	g	A graphic device object to be drawn into. This is normally e.Graphics from the PaintEventArgs argument to the Paint() method.
GraphPane	pane	A reference to the GraphPane object that is the parent or owner of this object.
Int32	pos	The ordinal position of the current ErrorBarItem curve.
Single	scaleFactor	The scaling factor to be used for rendering objects. This is calculated and passed down by the parent GraphPane object using the CalcScaleFactor() method, and is used to proportionally adjust font sizes, etc. according to the actual size of the graph.

Overrides

CurveItem.Draw(Graphics, GraphPane, Int32, Single)

DrawLegendKey(Graphics, GraphPane, RectangleF, Single)

Draw a legend key entry for this ErrorBarItem at the specified location

Declaration

public override void DrawLegendKey(Graphics g, GraphPane pane, RectangleF rect, float scaleFactor)

Parameters

Type	Name	Description
Graphics	g	A graphic device object to be drawn into. This is normally e.Graphics from the PaintEventArgs argument to the Paint() method.
GraphPane	pane	A reference to the GraphPane object that is the parent or owner of this object.
RectangleF	rect	The RectangleF struct that specifies the location for the legend key
Single	scaleFactor	The scaling factor to be used for rendering objects. This is calculated and passed down by the parent GraphPane object using the CalcScaleFactor() method, and is used to proportionally adjust font sizes, etc. according to the actual size of the graph.

Overrides

CurveItem.DrawLegendKey(Graphics, GraphPane, RectangleF, Single)

GetCoords(GraphPane, Int32, out String)

Determine the coords for the rectangle associated with a specified point for this CurveItem

Declaration

public override bool GetCoords(GraphPane pane, int i, out string coords)

Parameters

Type	Name	Description
GraphPane	pane	The GraphPane to which this curve belongs
Int32	i	The index of the point of interest
String	coords	A list of coordinates that represents the "rect" for this point (used in an html AREA tag)

Returns

Type	Description
Boolean	true if it's a valid point, false otherwise

Overrides

CurveItem.GetCoords(GraphPane, Int32, out String)

GetObjectData(SerializationInfo, StreamingContext)

Populates a SerializationInfo instance with the data needed to serialize the target object

Declaration

[SecurityPermission(SecurityAction.Demand, SerializationFormatter = true)]
public override void GetObjectData(SerializationInfo info, StreamingContext context)

Parameters

Type	Name	Description
SerializationInfo	info	A SerializationInfo instance that defines the serialized data
StreamingContext	context	A StreamingContext instance that contains the serialized data

Overrides

CurveItem.GetObjectData(SerializationInfo, StreamingContext)

Explicit Interface Implementations

ICloneable.Clone()

Implement the ICloneable interface in a typesafe manner by just calling the typed version of Clone()

Declaration

object ICloneable.Clone()

Returns

Type	Description
Object	A deep copy of this object

Implements

System.ICloneable

System.Runtime.Serialization.ISerializable
