### Colour coding

When viewed for today only, each section on the Details page gives an indication if it is currently alerting and thus impacting the associated heat tile colour. Find out more about [colour coding](https://help.highlight.net/details/details-page-options/colour-coding).&#x20;

### Description

**Horizontal axis:** Adjusts according to the selected time period to show "hours" in day view and "days" in week and month views; redraws if the time zone is changed at the top right of the Details page. See [Zoom options](https://help.highlight.net/details/details-page-options/zoom-options) for methods to zoom in on the data. &#x20;

**Time period**

Highlight displays the values for each data point in the time period:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td>Day</td><td>Shows multiple data points per hour (one for each polling period, usually one to five minutes)</td></tr><tr><td>Week</td><td>Shows 24 data points per day (every hour), Maximum for each hour is shown</td></tr><tr><td>Month</td><td>Shows 6 data points per day (every 4 hours), Maximum for each 4 hour period is shown</td></tr></tbody></table>

For any time period, hover on a point to see date, timestamp and availability status. If hovering on a week or month, there may be multiple availability states in the time period.

### Availability

Coloured blips, with the priority and meaning shown below, are drawn on the Availability line.

<table><thead><tr><th width="89">Priority</th><th width="126">Colour</th><th>Issue</th></tr></thead><tbody><tr><td>1</td><td>Red blip</td><td>Parent controller reported as down or is not contactable</td></tr><tr><td>2</td><td>Green line</td><td>Parent controller is up</td></tr><tr><td>3</td><td>Grey line</td><td>No data</td></tr></tbody></table>

#### Week/Month: Priority on availability states

For week or month, if more than one availability event occurs during the time span (one hour for a week, 4 hours for a month), then only one blip is shown on the Availability line using the priority shown in the table above.

All availability events for the time span are listed in the tooltip when hovering on a point.

### Health

Currently no blips are drawn on the Health line.&#x20;

### Zoom options

There are two methods to zoom in on charts: drag and click. Find out more about [zoom options.](https://help.highlight.net/details/details-page-options/zoom-options)
