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.
