Ar gyfer POLYGON AMLDER mae angen darganfod
canolbwynt pob grŵp, a plotio a cysylltu’r pwyntiau hyn.
For a FREQUENCY POLYGON you must find the
midpoint of each group, plot and join up these points.

•  rhoi teitl i bob graff, a labelu pob echelin
give each graph a title, and label each axis
•  defnyddio graddfa cyson
use a constant scale
•  ac ysgrifennu’r grwpiau ar yr echelin waelod
write the groups on the bottom axis
