+#### Refresh Time (in Seconds) {#refresh-time}
+
+The **Refresh time (in seconds)** property reloads a chart's data automatically. It is the last property in the **Data source** section. It is available for all chart types except **Custom chart**.
+
+* **0** (default) – Automatic refresh is disabled.
+* **Greater than 0** – The chart reloads all of its data sources this number of seconds after its data was last updated.
+
+Keep the following in mind:
+
+* The timer restarts every time the chart's data is updated. This means the chart reloads a set time after the most recent update, not at a fixed clock interval.
+* If a data source is still loading when the timer ends, it is not reloaded again.
+* The chart keeps showing its current data while it reloads, so it does not go blank between refreshes.
+
+Use this property when a chart cannot detect that its data has changed, for example when it shows data from a view entity or aggregated data.
