In a heterogeneous
panel, the cells in a graph are arranged in rows and columns. Each
cell is defined independently and can contain different types of plots.
For more information
about cells, see Components of a Graph.
You can
add multiple rows and columns to a graph. The limit to the number
of rows and columns that you can add depends on the size of your graph.
As you add more rows and columns, the individual cells shrink proportionally.
Here is
an example of a heterogeneous panel that has one column and two rows,
for a total of two cells:
You can
add only complete rows and columns to the graph. In addition, cells
cannot span across multiple rows or columns. For example, suppose
that you have a graph layout with two rows and two columns.
You cannot
have two cells in the first row and a merged single cell in the second
row.
However,
you can leave a cell blank as shown here.
