In the Graph Plots view, the graph plot modifiers in the toolbar control the type of output for the active channel(s).

The graph plot modifiers enable you to:

> Macro (scroll-only)
> 
> > Macro (toc)

Note that some options are only available when you select **Show advanced** > Macro (inline-media-image)

. This is noted in their descriptions.

> ⚠️ **Note**  
> ⚠️ In a similar way to selecting different **Channel** **Types** with an **Active Channel**, graph plot modifiers will:
> ⚠️ 
> ⚠️ - Add an additional set of subplots according to the last selected graph plot modifier (if applicable) if the channel is **pinned**
> ⚠️ - Change the graph type according to the last selected graph plot modifier (if applicable) if the channel is **not pinned**.

## Plot derivatives

| ![image](media://62702072-f778-4243-85a4-936f74129c09) | To choose whether to plot normal channel data (**No Derivative**) or a derivative (**Velocity** or **Acceleration**) for the selected channel(s), on the Graph Plots toolbar, click the **Derivative order** dropdown menu > Macro (inline-media-image) |

## Change the rotation type

| --- | --- |
| ![image](media://6581bfb9-878d-4d22-b147-04629f7f94ae) | To change the rotation type, on the Graph Plots toolbar, from the **Rotation format **list, select the required display:<br>- **Helical **format. Axis-angle representation comprising a unit vector that indicates the axis of the rotation, scaled by the angle describing the magnitude of the rotation about the axis.
- **Euler** format. Representation composed of 3 rotations about the axes of a coordinate system in a particular sequence.   
The Tait-Bryan set of Euler angle conventions are supported.<br>This is an advanced Graph Plot modifier. |

## Plot channel magnitude

> Macro (scroll-tablelayout)

|  |  |
| --- | --- |
| ![image](media://54e38b31-987d-40f9-9b06-3c033ae1746d) | To plot channel magnitude for the active channel(s), on the Graph Plots toolbar, select the **Channel magnitude** button.  
Depending on the current selection, when Channel magnitude is activated, the relevant magnitude is displayed.<br>See [Graph Plots reference](https://vicon-help.atlassian.net/wiki/spaces/Tracker40/pages/14192063) for more information on how the magnitude may affect your active channel. |

## Change the units

| ![image](media://9298c6d6-4280-49ef-831b-ebd0429eacbd) | To change the units for the active channel(s), on the Graph Plots toolbar, select the **Change selected channel units** button > Macro (inline-media-image)

. Choose from the following options:<br>- **Angle** Choose between degrees (°) or radians (rad)
- **Length** Choose between millimeters (mm), centimeters (cm) or meters (m)<br>Note that the units for each component is displayed with its label along the y-axis. This is an advanced Graph Plot modifier. |
