Methods

CalcRectangle(Graphics, GraphPane, Single, RectangleF)

Calculate the RectangleF that will be used to define the bounding rectangle of the GasGaugeNeedle.

Declaration
public static RectangleF CalcRectangle(Graphics g, GraphPane pane, float scaleFactor, RectangleF chartRect)
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 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.
RectangleF chartRect

The RectangleF (normally the Rect) that bounds this pie.
Returns
Type Description
RectangleF
Remarks

This rectangle always lies inside of the Rect, and it is normally a square so that the pie itself is not oval-shaped.

CalculateGasGuageParameters(GraphPane)

Calculate the values needed to properly display this GasGaugeRegion.

Declaration
public static void CalculateGasGuageParameters(GraphPane pane)
Parameters
Type Name Description
GraphPane pane

A graphic device object to be drawn into. This is normally e.Graphics from the PaintEventArgs argument to the Paint() method.

Draw(Graphics, GraphPane, Int32, Single)

Do all rendering associated with this GasGaugeRegion item 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

Not used for rendering GasGaugeNeedle
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.
