# How to set the interval colors in a gauge/meter graph

In this demo article we present how you can set the colors for the intervals in a gauge/meter graph.

### Data Source Annotations

 Series #1: Data source for value Series #1: Data source for min Series #1: Data source for max Series #1: Data source for label Series #1: Data source for intervals Series #1: Data source for interval_colors
Some explanations:
• Value: The value of the meter is the table cell , i.e. the cell on the 1st row, 1st column (which in this example is 14) because its data source was defined as: element: table row, range:1, element section:1
• Min: The min value of the meter is the table cell , i.e. the cell on the 1st row, 2nd column (which in this example is 7) because its data source was defined as: element: table row, range:1, element section:2
• Max: The max value of the meter is the table cell , i.e. the cell on the 1st row, 3rd column (which in this example is 66) because its data source was defined as: element: table row, range:1, element section:3
• Label: The label text of the meter is the table cell , i.e. the cell on the 1st row, 4th column (which in this example is Speed) because its data source was defined as: element: table row, range:1, element section:4
• Intervals: You can optionally split the min-max range with an arbitrary number of intervals. For each interval there should be a corresponding color defined in hex format (e.g. #ff0044). In this example the intervals are defined in the second row, because their data source was defined as : element: table row, range:2. The colors were defined in the row below (3rd row), as indicated by the corresponding data source: element: table row, range:3
