Hi, folks. I am trying to create a dashboard that displays a single value. (Splunk ver 8.0.1) I am trying to change the font color when there is more than 50% difference from the previous value. Since `rangemap` doesn't work well, I gave up single value dashboard. I tried to make it but it doesn't look **cool**. Please let me know if there is a good way to change the background color, font color, or display method.
