Constructors

Bar()

Default constructor that sets all Bar properties to default values as defined in the Bar.Default class.

Declaration

public Bar()

Properties

Border

The Border object used to draw the border around the Bar.

Declaration

Methods

Clone()

Typesafe, deep-copy clone method.

Declaration

public Bar Clone()

Returns

Type	Description
Bar	A new, independent copy of this class

Draw(Graphics, GraphPane, RectangleF, Single, Boolean, Boolean, PointPair)

Draw the Bar to the specified Graphics device at the specified location. This routine draws a single bar.

Declaration

public void Draw(Graphics g, GraphPane pane, RectangleF rect, float scaleFactor, bool fullFrame, bool isSelected, PointPair dataValue)

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 rectangle (pixels) to contain the bar
Single	scaleFactor	The scaling factor for the features of the graph based on the BaseDimension. This scaling factor is calculated by the CalcScaleFactor() method. The scale factor represents a linear multiple to be applied to font sizes, symbol sizes, etc.
Boolean	fullFrame	true to draw the bottom portion of the border around the bar (this is for legend entries)
Boolean	isSelected	Indicates that the Bar should be drawn with attributes from the Selection class.
PointPair	dataValue	The data value to be used for a value-based color gradient. This is only applicable for GradientByX, GradientByY or GradientByZ.

Draw(Graphics, GraphPane, Single, Single, Single, Single, Single, Boolean, Boolean, PointPair)

Draw the Bar to the specified Graphics device at the specified location. This routine draws a single bar.

Declaration

public void Draw(Graphics g, GraphPane pane, float left, float right, float top, float bottom, float scaleFactor, bool fullFrame, bool isSelected, PointPair dataValue)

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.
Single	left	The x position of the left side of the bar in pixel units
Single	right	The x position of the right side of the bar in pixel units
Single	top	The y position of the top of the bar in pixel units
Single	bottom	The y position of the bottom of the bar in pixel units
Single	scaleFactor	The scaling factor for the features of the graph based on the BaseDimension. This scaling factor is calculated by the CalcScaleFactor() method. The scale factor represents a linear multiple to be applied to font sizes, symbol sizes, etc.
Boolean	fullFrame	true to draw the bottom portion of the border around the bar (this is for legend entries)
Boolean	isSelected	Indicates that the Bar should be drawn with attributes from the Selection class.
PointPair	dataValue	The data value to be used for a value-based color gradient. This is only applicable for GradientByX, GradientByY or GradientByZ.

DrawBars(Graphics, GraphPane, CurveItem, Axis, Axis, Single, Int32, Single)

Draw the this Bar to the specified Graphics device as a bar at each defined point. This method is normally only called by the Draw(Graphics, GraphPane, Int32, Single) method of the BarItem object

Declaration

public void DrawBars(Graphics g, GraphPane pane, CurveItem curve, Axis baseAxis, Axis valueAxis, float barWidth, 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.
CurveItem	curve	A CurveItem object representing the Bar's to be drawn.
Axis	baseAxis	The Axis class instance that defines the base (independent) axis for the Bar
Axis	valueAxis	The Axis class instance that defines the value (dependent) axis for the Bar
Single	barWidth	The width of each bar, in pixels.
Int32	pos	The ordinal position of the this bar series (0=first bar, 1=second bar, etc.) in the cluster of bars.
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.

DrawSingleBar(Graphics, GraphPane, CurveItem, Int32, Int32, Axis, Axis, Single, Single)

Protected internal routine that draws the specified single bar (an individual "point") of this series to the specified Graphics device.

Declaration

protected virtual void DrawSingleBar(Graphics g, GraphPane pane, CurveItem curve, int index, int pos, Axis baseAxis, Axis valueAxis, float barWidth, 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.
CurveItem	curve	A CurveItem object representing the Bar's to be drawn.
Int32	index	The zero-based index number for the single bar to be drawn.
Int32	pos	The ordinal position of the this bar series (0=first bar, 1=second bar, etc.) in the cluster of bars.
Axis	baseAxis	The Axis class instance that defines the base (independent) axis for the Bar
Axis	valueAxis	The Axis class instance that defines the value (dependent) axis for the Bar
Single	barWidth	The width of each bar, in pixels.
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.

DrawSingleBar(Graphics, GraphPane, CurveItem, Axis, Axis, Int32, Int32, Single, Single)

Draw the specified single bar (an individual "point") of this series to the specified Graphics device. This method is not as efficient as DrawBars(Graphics, GraphPane, CurveItem, Axis, Axis, Single, Int32, Single), which draws the bars for all points. It is intended to be used only for SortedOverlay, which requires special handling of each bar.

Declaration

public void DrawSingleBar(Graphics g, GraphPane pane, CurveItem curve, Axis baseAxis, Axis valueAxis, int pos, int index, float barWidth, 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.
CurveItem	curve	A CurveItem object representing the Bar's to be drawn.
Axis	baseAxis	The Axis class instance that defines the base (independent) axis for the Bar
Axis	valueAxis	The Axis class instance that defines the value (dependent) axis for the Bar
Int32	pos	The ordinal position of the this bar series (0=first bar, 1=second bar, etc.) in the cluster of bars.
Int32	index	The zero-based index number for the single bar to be drawn.
Single	barWidth	The width of each bar, in pixels.
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.
