The topics in this section explain how to use controls in Graph Plots to manage the channels, including how to display or hide the key and how to pin and unpin channels.
> Macro (toc)
## Display or hide a key for the graph
> Macro (scroll-tablelayout)
| | |
| --- | --- |
|  | To toggle the display of selected or pinned channels, select the ** Channel Key ** button on the far right of the Graph Plots toolbar.
For more information, see [Use the Channel Key](#ChannelKey). |
> Macro (scroll-pagebreak)
## > Macro (anchor)
Use the Channel Key
The Channel Key displays a list of the active channels. If the subplot layout is set to Single Plot, component names are also displayed, with each channel component displayed in a different color.
> ✅ **Tip**
> ✅ To pin/unpin all or remove all channels, right-click a line in the key and select the relevant option.

| **Subplot Per Type layout**
> Macro (inline-media-image)
**Single Plot layout**
> Macro (inline-media-image) | - Color patch – The color used for corresponding traces.
For information on how to change the colors used for each trace, see [Preferences options](https://vicon-help.atlassian.net/wiki/spaces/Tracker44/pages/376308389).
- Component name
- Channel name
- Pin button – Click to toggle the relevant channel's pin status.
- Remove button – Click to remove the relevant channel. This removes its traces from the graph and de-selects any input channel sources.
- Dependent channel entries are highlighted when all their input channel sources are selected.
- Independent channels are highlighted when they are the current channel type. |

Select and pin channels
Selecting a channel source automatically adds one trace for each of its components, creating subplots as required for each channel component type. Deselecting a channel source removes the traces (and any empty subplots).
Pinning a channel prevents removal of traces on deselection.
**To pin a channel, do either of the following:**
- Open the Channel Key and click the relevant Pin button > Macro (inline-media-image)
for the component and channel name
or
- Right-click in a Graph Plots view, select **Pin Channel **and then select the relevant component or channel (see [Graph Plots mouse actions](https://vicon-help.atlassian.net/wiki/spaces/Tracker44/pages/376309475)).
Pinning is useful for building plots of disparate types, or comparing multiple selected channels to a reference channel.

### Show or hide channel details
> Macro (scroll-tablelayout)
| | |
| --- | --- |
|  | Select the **Show channel details** button to the right of the **Channel Key** heading to display or hide details of the channels displayed in the key, including the current channel values, channel means, and channel standard deviations.
- Mean and standard deviation are computed over the range of data stored in the channel cache.
- For live data, the size of this range is controlled by the live data range (see [Change the scale of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker44/pages/376309436))
- For review data, the whole clip range is used. |
### Show or hide channel value tooltip
> Macro (scroll-tablelayout)
| | |
| --- | --- |
|  | Select the **Show channel value tooltip** button to display a tooltip when you hover the mouse pointer over a subplot. The tooltip indicates value and frame/sample numbers at the current time/position of the mouse pointer. |
### Set the opacity of lines between gaps in channel data
> Macro (scroll-tablelayout)
| | |
| --- | --- |
|  | Select the **Change opacity** button and move the slider to change the opacity of lines drawn between gaps in the channel data |
