### Overview

This section shows graphically the number of clients for the selected time period (day, week, month) and date. It also shows the percent of clients with signal problems.

### 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](/details/details-page-options/colour-coding.md).&#x20;

### Client Count description

A vertical bar is drawn on the chart for each poll (typically every five minutes). When client numbers are at or below the threshold, the vertical bar is green. When client numbers exceed the threshold, the section of the vertical bar above the threshold is red.

#### Threshold

The custom defined threshold is indicated with a thin horizontal purple line and shown in purple text in the right margin. The threshold is 30 client devices by default and can be altered by Admin users. See [WiFi Alerting Thresholds](https://support.highlight.net/help/admin/alerting_thresholds#wifi) for more information.\
If configured, an alert can be sent when client count exceeds the threshold.

**Vertical axis:**  Scaling adjusts depending on data

**Threshold (30 clients):**  If the adjusted vertical axis means the threshold line is not visible then a purple arrow is shown indicating the threshold is above the visible chart area.

**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

### 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, client count and signal problem as a percentage.

### Signal Problems

Colours on the line represent the percent of clients with signal problems as:

<table data-view="cards"><thead><tr><th></th><th></th></tr></thead><tbody><tr><td><strong>Green</strong></td><td>Values are at or below the threshold</td></tr><tr><td><strong>Red blips</strong></td><td>Values exceed the threshold</td></tr><tr><td><strong>Grey</strong></td><td>No samples or client count of 0%</td></tr></tbody></table>

#### Threshold

The threshold for signal problems is set to 25% by default and can be altered by Admin users. This is 25% of clients on an AP with poor signal strength. A poor signal strength is defined as one or two bars or below 20 decibels. The custom threshold is shown in purple text in the right margin. See [WiFi Alerting Thresholds](https://support.highlight.net/help/admin/alerting_thresholds#wifi) for more information.\
If configured, an alert can be sent when signal problems exceed the threshold.

### Zoom options

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

### Background colours

Grey backgrounds indicate non-business hours and purple backgrounds indicate maintenance periods.  Find out more about [background colours](/details/details-page-options/background-colours.md).
