In the Graph Plots view, you can display and select your data (for example, x, y, and z components of a marker trajectory) in graph format, plotted against time.

Display data in a Graph Plots view

To display a graph in a Graph Plots view:

1. Ensure that in the Workspace, the Graph Plots view is selected.

   

   Important If your Graph plots view displays No channel data available or a similar message, make sure you either have a live system connected or are reviewing a capture (see Prepare your Vicon system).

   

2. At the top left of the Graph Plots view, click the channel types menu and select the required channel type.

   

   You can choose to display an independent channel (listed in bold text) or a dependent channel. If you want to display a dependent channel, you must select a channel source which can be:

   • A subject in the Tracking panel
   • A marker, prop or segment in the 3D View. A segment can be a labeling segment (prop or subject labeling skeleton), solving segment (subject solving skeleton) or retarget segment (subject retargeting skeleton).
     
   • A camera in the System panel or Cameras view

   Tip If you select a dependent channel type and have not yet selected the required channel source(s), the Graph Plots view displays a message telling you the channel source(s) that you must select to display the selected channel type.

3. Change the data displayed in the active channel using additional controls in the Graph Plots toolbar. For more information, see: 

• • Change the type of graphed data (eg, derivatives)
  • Change the layout of graphed data

  • Change the scale of graphed data 

To add a graph trace to a subplot in Graph Plots:

If you already have at least one channel active in a Graph Plots view and want to add a trace to a subplot:

1. Make sure you have pinned all the channels that you would like to keep (see Manage channels).
   If a channel is not pinned, it will be removed from the Graph Plots view.
2. When you have pinned all the desired channels, you can:
   • Add a trace to the existing graphs (for example, add the position data of Camera 2 to an existing graph of the position data of Camera 1)
   • Change the processing applied to the active channel type by selecting one of the graph plot modifiers (see Change the type of graphed data)
   • Select a new channel type from the list of channel types at the top left of the Graph Plots view.

   • Select a new channel source by clicking on the device, object, or marker in the relevant panels or views.

3. If you want to keep the newly added channel and add more channels, remember to pin it.

Customize graph plots

To customize the data displayed in the Graph Plots window, first choose your data (see Change the type of graphed data) and then make sure the desired channels are pinned (see Manage channels).

When you have chosen the required channel type(s) to plot, you can customize the way your data is displayed by selecting options from the Graph Plots toolbar to make the following changes:

• Change the layout of graphed data
• Change the scale of graphed data

As you customize your graph plots, see Graph Plots mouse actions to understand how to control the behavior of the graph plots window. 

Manage graph plots

After you have added all the desired channels and customized the layout of the Graph Plot window, you can also:

• Lock the current selection of channels using the Lock channel selection button . When selected, clicking on potential channel sources does not add or remove channels. See Lock channel selection.
• Save the current Graph Plot layout (including pinned channels) or load a previous Graph Plot layout using Graph Settings. See Save and load Graph Plots layouts.

Lock channel selection

When the Lock channel selection button is activated, selecting or de-selecting channel sources does not add or remove graph channels to/from the current Graph Plot window. You can still change the layout of your Graph Plots but not the channels themselves (see Change the layout of graphed data).

Save and load Graph Plots layouts

Use the Graph Settings to save and load a specific layout in the Graph Plots window. This includes any channels that are pinned (even if they are not present in the current session) or locked using Lock channel selection. It also includes the settings specified within the graph plot modifiers (see Change the type of graphed data).

Graph Settings only apply to the Graph Plots window and are a subset of the overall View Settings (see Live - Customize views).  This means:

• You can load different Graph Plot layouts while maintaining the current Shogun layout.
• Loading a View setting will load the graph settings that were specified as a part of that View configuration.

• Graph Settings do not have a specific auto-save feature but are included as part of the View Settings auto-save.

To change the interval at which files are auto-saved, go to Preferences (Shift+P), select User Preferences > General , and change the value in the Auto-save interval field from the default (60 seconds).

To save new graph settings:

1. On the Graph Plots toolbar, click Graph Settings .
2. Click Manage.
3. In the Manage Graph Settings dialog box, click the Save button.
4. Enter a name for the graph settings to save.
5. Click OK.

You can now select your saved settings from the Graph Settings menu.

To load previously saved graph settings:

On the Graph Plots toolbar, click Graph Settings and select the settings from the list.

Alternatively, import the required settings. To import settings:

1. On the Graph Plots toolbar, click Graph Settings .
2. Click Manage.
3. In the Manage Graph Settings dialog box, click the Import button.

4. Select the settings to import.

   Tip Settings have the extension .Graph.

5. Click OK.
