Adding a baseline to a visualization
Baselines are horizontal or vertical lines that cut through the chart to indicate major
divisions in the data.
About this task
In visualizations, you can define baselines by values on the numeric axis or the category axis.
Each baseline represents a value on an axis.
Depending on the type of visualization, you can use the following options to position the baseline.
Note: If you use queries in baselines
that are based on report expressions and query calculations, then these queries and query
calculations must come from the same data source as the visualization itself.
Option | Description |
---|---|
Numeric Value |
Uses a static numeric value. |
Category Index |
Uses the index value of the data item in the categories axis. For example, a Category index value of 1 indicates that the baseline is at the first data item. This is the default. |
Percent on Axis (%) |
Uses a percentage of the full range of the axis. For example, if the axis range is -500 to 1100, a Percent on Axis value of 25% puts the baseline at -100 (25% of the range, 1600). |
Query calculation |
Uses a query calculation to determine the position of the baseline. For more information, see Insert a Query Calculation. |
Layout calculation |
Uses a layout calculation to determine the position of the baseline. For more information, see Create a Layout Calculation. |
