Use Grid layout when the X-coordinates of each point and the Y-coordinates of each point are always the same distance apart. The following diagram illustrates the characteristics of Grid layout.
The important Grid layout characteristics are:
•The number of rows and columns, the origins, and the single row and column delta value defines the X/Y grid.
•The grid spacing for all rows is set by the RowDelta property. The grid spacing for all columns is set by the ColumnDelta property.
