Tips

• If the circles are not visible or are under the bars, check the order of the fields in double axles (Rows or Columns). Invert them if necessary to ensure that the circles appear in the foreground,
• Use dynamic colors or conditional calculations to highlight specific values, such as the best or worst performers. This draws your audience's attention to the most relevant information,
• Remove superfluous visual elements, such as grid lines or borders, for a cleaner, more professional look. A well-structured dashboard inspires confidence and makes it easy to understand.
