Displaying a Grid
A grid is a graphical indicator of data values. A grid is attached to a scale and is composed of the following:
-
Major lines drawn at the positions of the major ticks of the scale
-
Minor lines drawn at the positions of the minor ticks of the scale
A grid is displayed within a chart by a dedicated object called a grid displayer.
The base class used to represent a grid displayer is the IlvAbstractGridDisplayer class.
