# Gauges

Gauges show a single value. Each row of the dataset draws a single gauge.

| Query Requirements | **First Column: Text Second Column: Numeric**  The query must return two columns, the first being the gauge name, and the second being the value. |
|---|---|
| Multiple Plots | **No**  Gauges only show a single data series. |
| Axis Overrides | **Y Axis**  The Y axis limits are used to set the range of the gauges. If not specified, the default range is 0 - 100. |
| Data Formatting | **No**  Gauge values are always shown as integers. |
| Extra Columns | **No**  The API does not support any extra columns for gauges. |

### Yellow and Red Zones

You can set these using the ***extra options*** field. In the example above, the following extra options are specified:

,redFrom:90, redTo:100, yellowFrom:75, yellowTo:90, minorTicks:10

Refer to the [Extra Option](https://manuals.remository.com/plotalot/charts/the-chart-editor#extra-options) section for more details about the syntax.
