This displays the difference between two fields from either the table or chart. The variance can be displayed as either the calculated value, or a % difference.

OptionDescription
Variance NameThis specifies the display name of the resulting variance field, used in the chart labels and/or legend.
Variance Between

This allows you to select two fields or data sets to apply the variance calculation to. The values in the second field will be subtracted from the values in the first field, as part of the calculation, so order is important.

These are the types of field available to be used as part of a variance (selected through the drop-down):

  1. Chart Fields - all standard fields used in a chart will be available, as well as:
    1. Chart Aggregated fields - this means you could calculate the variance between the chart aggregated field and it's original report field.
    2. Set Analysis fields - this means that you can calculate the variance between two sets that have already been created.
  2. Report Fields - all metrics included in your table. This means that you don't necessarily have to use a metric in your chart to include it in the variance calculation.

Or enable the Custom Set toggle to perform set analysis through the Create button.

Display Variance as

This allows you to select how the resulting variance values are displayed. There are four options:

  1. # Value Value - This will display the result of subtracting field one from field two, as a number.
  2. % Percentage of Variance - This will display the result of subtracting field one from field two, divided by value one (a percentage result).
  3. Simple Percentage - This will display the result of dividing field one by field two.
  4. Percentage % of Total Variance - This calculates the  percentage of the total variance. (The total variance is either set on the report/chart field or is the default sum.)
  5. % Percentage Change in Relative Proportion - Use this formula to calculate the percentage change in relative proportion. That is, the percentage of the total second value is subtracted from the percentage of the total first value, and this amount is divided by the percentage of the total second value. (The total is either set on the values, or is the default sum.)
