Points

The Points element shows data values as points.

Figure 3.25 Points Options 

Summary Statistic

Changes the statistic being plotted. The statistic is calculated using the variable on the Response Axis. None is the default setting, indicating that the data values themselves are plotted.

Error Interval

Adds or removes specified error interval in the graph.

Interval Style

Draws error bars or error bands for the selected error interval.

Jitter

Jitter adds random noise to values to reduce over-plotting. Choose from the following types of jitter:

None

No adjustments are made.

Auto

Adds various types of jitter when categorical variables are involved. No jitter is added when you have only continuous variables.

Random Uniform

Random offset with uniform distribution.

Random Normal

Random offset with Gaussian distribution.

Packed

Places markers tightly to preserve any non-jittered dimensions.

Centered Grid

Similar to Packed, but adjusts the non-jittered dimensions to fall into a grid.

Positive Grid

Similar to Center Grid, but in the positive direction.

You can also customize jitter by right-clicking and selecting Customize > Marker.

Tip: To create a dot plot, select the Positive Grid option. You can move the dot plot to start at the bottom by changing the Y-axis values to 0-1. You can also resize the markers to a larger value, such as 20, to adjust the binning of the dots.

Jitter Limit

Controls the spread or amount of overlap.

Variables

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 in the Graph Builder Examples section.
