Spread Graph Settings

The Spread Graph displays the variance or spread between two time-based data series.

Typical use cases include comparing a stock’s price performance to an Index or a bond’s yield to a benchmark rate.

The spread graph settings pane is displayed after clicking the Options button.

Positive Spread Color	Specifies the color when the spread between the value and reference is positive.
Negative Spread Color	Specifies the color when the spread between the value and reference is negative.

Other visualization-specific properties can be set by clicking on the Y-Axis variable drop area and then selecting the Y-Axis tab:

Setting	Description
Independent Y-Axis Scaling	Determines whether to have each visualization Y-axis in a cross tab automatically scaled independent of the others.
