The LAYOUT GRIDDED Statement

The GTL provides several layout types to organize your graph into smaller regions (cells). The GRIDDED and LATTICE layouts support a regular grid of cells with a fixed number of rows and columns. The DATALATTICE and DATAPANEL layouts generate classification panels, which are graphs where the number of cells and the cell content are determined by the values of one or more classification variables.

The GRIDDED layout differs from the classification panel layouts in that the number of cells must be predefined and that you must define of the content of each cell separately. GRIDDED is superficially similar to a LATTICE layout because it can create a grid of heterogeneous plots. However, the LATTICE layout can automatically align plot areas across columns and rows and has much more functionality. For more information on the LATTICE layout, see Using an Advanced Multi-cell Layout.

Typical applications of GRIDDED layouts are to create

In a GRIDDED layout, each cell is independent. Contents of the cell can be specified by a stand-alone plot statement or a nested layout. The following example shows a very simple GRIDDED layout:

proc template;
  define statgraph intro;
    begingraph;
      entrytitle "Two-Cell Gridded Layout";
      layout gridded;
        barchart x=age;
        scatterplot x=height y=weight;
      endlayout;
    endgraph;
  end;
run;

proc sgrender data=sashelp.class template=intro;
run;

In this case, each plot statement is considered independent and is placed in a separate cell. When no grid size is provided, the default layout creates a graph with one column of cells, and it allots each cell the same amount of space. The number of rows in the grid is determined by the number and arrangement of stand-alone plot statements and nested layouts in the GRIDDED layout block.
