This is a 'linepoints' plot (Lines/Points) showing all the point shapes
|
|
|
4 |
available for 'point' and 'linepoints' plots. In this example, we also
|
|
|
5 |
use a legend to display a text string for each data set, and change the
|
|
|
6 |
data colors to get a different color for each point shape.
|
|
|
7 |
Note that the point shape sizes have been increased to 10 in this example,
|
|
|
8 |
to make them easier to identify.
