Answer
You will need 5 items;
- A field for indicating the pointer-value. In the example the number in the middle and the yellow marker
- Gauge minimum
- Gauge maximum
- One and Two indicate the chart intervals (1 time for the gap, other time for color). Adding more of these will add more gaps/intervals (alter the json for this)
Don't forget to download the JS-charting files and place them in your resource-folder
