Color coding is a simple but effective way of data visualization. You can use it, for instance, in the student grading system to help your users easily identify their grades. This article explains how to apply custom background and font colors conditionally based on the values in a report.


In this example, we applied different colors and backgrounds to the letter grade column.

  1. Edit your report DataPages (that is, Tabular, List, or Gallery).
  2. Proceed to the Configure Results Page section.
  3. Add an HTML block.
  4. Disable the HTML Editor.
  5. Enter a label name in the Label section of the HTML block, i.e., Letter Grade.
  6. Copy and paste the following JavaScript in the HTML block.
  7. Replace [@field:ID#] with the unique field from your table or a view used as a data source. Add this field from the insert picker to avoid syntax errors.
  8. Add conditions relevant to your use case within the if(…) block.
  9. Save the DataPage.
