Remarks
This class is used to define the position of a chart element, and represents one rectangle via the X, Y, Width and Height properties.
The ElementPosition class is always exposed as a Position object property (e.g. ChartArea.Position, Legend.Position, etc.). It is also exposed in the Paint and BackPaint events as a property of the ChartPaintEventArgs object.
The position of the applicable chart elements can be set automatically by setting the Auto property to TRUE, and chart elements can also be positioned at design-time via the Design View.
Two major differences between this class and a RectangleF structure are:
-
This class can use automatic positioning.
-
This class ONLY uses coordinates ranging from 0 to 100, otherwise an exception is thrown.
The position of chart elements is described using relative coordinates, with the top-left corner of an element having coordinates of "0,0" and the bottom-right corner of an element having coordinates of "100,100". Elements that are plotted within a chart area use coordinates that are relative to the chart area, while elements outside of a chart area use coordinates that are relative to the chart picture.
