The Ellipse element Image shown here shows a bivariate normal density ellipse.

Figure 3.28 Ellipse Options 

Ellipse Options


Specifies the coverage percentage (99%, 95%, 90%, or 50%) for the density ellipse.


Shows the Pearson correlation coefficient for the X and Y variables on the graph.

Mean Point

Shows the mean on the graph.


Shows or hides graph elements for variables, or re-orders the display of variables.

Note: These options do not apply to variables in the Group X, Group Y, Wrap, or Page zones.

Check boxes are followed by the zone designation and the name of the variable. Use check boxes to do the following:

Show or hide the elements corresponding to a variable in a zone.

Add or remove the effect of applying the Color, Size, Shape, or Freq variable to the variable in the zone.

Tip: If you have multiple graphs, you can color or size each graph by different variables. Drag a second variable to the Color or Size zone, and drop it in a corner. In the Variables option, select the specific color or size variable to apply to each graph.

Use arrows to re-order the display if there are multiple variables in a zone. Highlight a variable name and click an arrow to reposition it.

For an example using Variables, see Example of an Area and Line Chart.
