This is a 'linepoints' plot (Lines/Points) showing all the point shapes
available for 'point' and 'linepoints' plots. In this example, we also
use a legend to display a text string for each data set, and change the
data colors to get a different color for each point shape.
Note that the point shape sizes have been increased to 10 in this example,
to make them easier to identify.
