Scale Tab
The Scale tab offers the following options for measure (numerical) legends.
What is a measure?A measure is generally used for aggregation, for example summation, averaging, correlation, etc., within a Crosstab, Chart, Text component, or Gauge. Adding a measure to the ‘Y’ region in a chart displays the computed aggregates by using locations on the Y-axis. Adding a measure to the ‘X’ region displays the computed aggregates by using locations on the X-axis. You can also display aggregates by using color, shape, size, or label. |
- Logarithmic Scale
-
Set logarithmic scaling for the legend scale. (The logarithm base is selected automatically.)
- Reverse
-
Orient the scale with maximum at left, minimum at right (or maximum represented by smallest, minimum represented by largest, etc.).
- Include Zero
-
For a ‘Size’ legend, specifies that zero should be included in the scaling such that the (hypothetical) minimum element size corresponds to a value of zero rather than the actual minimum data value.
Alias Tab
The Alias tab is available for dimension (categorical) legends, and displays a table containing the mapping between original legend labels and new legend labels.
What is a dimension?A dimension is used to break-down the dataset into multiple groups, often within a Crosstab, Chart, or Selection List. Adding a dimension to the ‘X’ region of a Chart distinguishes the different dimension groups by location on the X-axis. Adding a dimension to the ‘Y’ region distinguishes the different dimension groups by location on the Y-axis. You can add multiple dimensions into the ‘X’ or ‘Y’ regions of a Chart, or into the ‘Rows’ or ‘Columns’ regions of a Crosstab, to create multiple grouping levels. You can also distinguish groups in a dimension by using color, shape, size, or label in a Chart. |
To modify the labels of a legend, double-click the cells in the ‘Alias’ column that correspond to the legend labels that you wish to rename, and enter the desired replacement text. Press OK to close the panel.
This updates the legend labels with the specified replacement text.
