# Auto-Refresh

The "refresh" parameter automatically re-draws charts at regular intervals. The chart data is re-loaded from the server using Ajax, and the chart is re-drawn in-situ without re-drawing the entire page. This works for all charts and Google Tables, but not for Plotalot tables, Responsive tables, or single items.

```
{plotalot id="42" refresh="30"}
```

In this example the chart will re re-drawn using the latest data every 30 seconds. You can see auto-refresh in action by making a Gauge chart with a query of:

```
SELECT "Time", SECOND(CURRENT_TIME())
```
