The History section shows a graphic display of the Broadcaster's activity and performance over time. You can create an **Incident** to group together related network failures and see network data for the relevant time period. This is done by selecting a time range on a graph and clicking the **Open Incident** button. For more information about Incidents, see [Incidents](docId\:KM0I5TNPzuO-ygFv6QcVq) .

Data is shown on separate line graphs for each topic that is relevant for the selected Broadcaster. Click on the section headings to expand/collapse the graph display.

Each graph shows color coded lines indicating the events that occurred over time. A key indicating the colors used to represent various types of data is shown below each graph.

The graphs have the following functionality:

- Set the time range of the display either by selecting one of the preset time ranges or by entering a custom time range. (Default: *Last 6 hr*)
- Manually refresh graph data or set the automatic refresh frequency.
- Hover over a point on the graph to show the total values for that time.
- Click and drag the cursor over a time range to zoom in on that time range.
- Double click on the graph to zoom out on the graph (i.e. expand the time range).
- Click on the title of a data element in the key to display only that element.

:::hint{type="info"}
* The granularity of the graph depends on the zoom level. Most graphs can zoom in to a resolution of one datapoint per minute.
* For broadcasters v14.1+, data is gathered at 5 second intervals. This enables ZEN Master to show min. and max. values for RTT, jitter and bitrates based on 5 second intervals within a given data point.
