Visualization Properties in Expressions

---

In some cases, you may want to use the expression or the display name currently set on an axis as a dynamic part of another expression, so that it changes with your selections. For example, this may be interesting in a visualization title or in a tooltip or label. You may also want one axis to be automatically set to use the same expression as the one set on another axis.

There are a number of different "axis expressions working like properties" available in the visualizations. These properties exist only in the context of a visualization and they have values that are defined by the currently used settings in the visualization. For example, a scatter plot can expose the display name of its X and Y-axis expressions as properties and these can in turn be used to set the visualization title.

The syntax to use is ${Axis.Axis Name.DisplayName} and ${Axis.Axis Name.Expression}, for the display name and the underlying expression, respectively. For example, if the Axis Name is "X", the expression should refer to ${Axis.X.DisplayName} or ${Axis.X.Expression}. Note that the actual axis names to use may be different in two similar looking visualizations, see below. The ${DataTable.DisplayName} property can be used in all visualizations to retrieve the name of the main data table used in the visualization.

These properties can be used the same way as other types of properties. All of the display name-properties listed below also have a corresponding property for the actual expression.
