I have three single value panels at the top of my dashboard that I want to have color coded values or backgrounds for, but I want to pick the color of each one and have it stay that color. Using a range won't guarantee that my colors stay as I chose them as the values shift over time.
Is there a way to manually choose the colors for a single value visualization without relying on a range to do it via xml tags only?
I cannot create a custom css file to pull from so anything outside of tags in the dashboard xml is a no go.
If you want to set the foreground or background color for a dashboard panel, you can. For example, in a chart you can do this in the XML:
<panel> <chart> ... <option name="charting.backgroundColor">0xFF9900</option> <chart> </panel>
This should set the chart background color to orange. Here is the page in the Dashboards and Visualization manual: Chart configuration reference.
