The Line element

uses line segments to connect summary statistic values (or raw values) of the variable plotted on the Response Axis across the values or categories of another variable.

Note: If any of the rows used in calculating a point on the plot are hidden and not excluded, the point is not shown, but the position that it would occupy remains. The line segment connects the adjoining points.

Figure 2.30 Line Options

Connects points with line segments in the order of their row numbers.

Changes the connection type to a line, curve, step, centered step, horizontal, or vertical line. If you select a curve, you can also change the smoothness.

Changes the smoothness of a Curve connection. To use this option, select Curve for the Connection type.

Specifies the axis for the variable that is used as the response in plotting the line segments. The Auto setting is the Y axis.

Summary Statistic

Specifies the statistic that is plotted. The statistic is computed for observations at each distinct value of the variable in the X zone (or the Y zone, if X is specified as the Response Axis).

Adds or removes error bars in the graph.

Missing Factors

Provides options for connections when all values are missing for a setting of the variable on the X-axis:

Skips over the missing factor value, connecting the previous factor to the next factor.

Treat as Missing

Skips over the missing factor value, connecting the previous factor to the next factor. Draws the connection in the style specified for Missing Values.

Treats the missing factor values as zero.

Provides options for connections when all values are missing for a setting of the variable on the Response axis:

Connect Through

Connects the points adjacent to the missing values with the connector type used for the remaining points.

Connects the points adjacent to the missing values with a faded connection.

Connects the points adjacent to the missing values with a dashed connection.

Shows no connection between the points adjacent to the missing values.

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.
