It provides a simple line graph showing the value of the channel (or channels, as this [[panel types|type]] of panel can show several channels at once) over time.

===Interactions===

==With The Line==

**Hover** your mouse over a line to see details of the channel at that point in time.

**Left-click** on an individual line to open the [[channel navigation menu|navigation menu]] for that channel. 

This allows you to follow that channel to the asset it belongs to, trend it over time, compare it to other points of data, or view other values like it across your system.

**Right-click** on the line to open the [[edit menu|editing menu]] for that channel. This will allow you to change the type of the chart, as well as moving the channel to a different panels.

==With the Background==

**Hover** your mouse over the background to see the value of //each// of your channels at that point in time.

**Left-click and drag** to highlight a period of time. When you release the mouse button, you'll zoom in on that time-frame.

**Right-click** top open the menu and alter the scaling. By default, your line chart will be scaled to the minimum and maximum values of your channel. In some cases, this ends up being far too zoomed-out for you to see detail. To resolve this, right-click on the background of the chart, choose **Scale** and change it from **Full Range** to **Auto**.

Left-clicking on the background opens up a few options for analytic reports and navigation.
