Fill Opacity

This setting is available if the Threshold Type is set to Area. With this setting, you can adjust the opacity of the threshold’s inner area with a value between 0 and 100.

  • 0%: The threshold area fill will be completely transparent and not visible at all.
  • 50%: The threshold area fill will be semi-transparent, applying a subtle shade over the chart elements and the background in your selected Fill Color.
  • 100%: The threshold area fill will be completely opaque, fully displaying your selected Fill Color.
