--- title: "Graphing your data" canonical: "https://help.vicon.com/space/Tracker43/344557020/Graphing%20your%20data" format: markdown --- 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 – see [About the Graph Plots view](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344555906). > ℹ️ **Note** > ℹ️ For definitions of the terminology used for graphing, see [Graph Plots terminology](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557146). For more information, see the following topics in this section. > Macro (scroll-only) > > > Macro (toc) ## Display data in a Graph Plots view **To display a graph in a Graph Plots view:** 1. In the **Workspace**, ensure the **Graph Plots** view is selected. :check_mark: **Important**: If the Graph Plots view displays **No active channels** or a similar message, make sure you either have a live system connected (see [Prepare your Vicon Tracker system](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344555662)) or are in review mode (see [Review captures](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557399)). 2. At the top left of the Graph Plots view, click either the selected channel types menu or the global channel types menu and select the channel to display. The selected channel type displays channel-dependent data that requires you to select a channel source, such as: - An analog device in the **System** panel - An object in the **Tracking** panel - A marker or object in the **3D View** - A camera in the **System** panel or **Cameras** view :check_mark: **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. For more information about channel types, see [Graph Plots reference](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557290). By default, **Auto** is selected. When a channel source is selected, Tracker automatically adds the primary channel type to the Graph Plots. For example, if you select an object in the Tracking panel, the Position and Rotation channel type is automatically displayed. :warning: **Note**: You can only add selected channels if the Selection Link > Macro (inline-media-image) is activated, otherwise, you can only add global channels. The **global channel type**  displays independent channels that do not require you to select a channel source, such as: - The number of objects currently tracked (Tracked Count) - The number of object markers currently tracked (Labeled Marker Count) 3. Change the displayed data within the active channel using additional controls in the Graph Plots toolbar. For more information, see: - [Change the type of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557152) (eg, derivatives) - [Change the layout of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557188) - [Change the scale of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557215) ** 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](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557260) ). 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 (that is, adding the position data of Object2 to an existing graph of position data of Object1). - Change the processing applied to the active channel type by selecting one of the graph plot modifiers (see [Change the type of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557152)). - Select new channel type from the **Channel Types** menu. - Select a new channel source by clicking on the device, object, or marker from the relevant panels or views. 3. If you want to keep the newly added channel and add additional channels, you must pin it. - Ensure that the Channel Key is visible using the Show channel key > Macro (inline-media-image) - Toggle to pin > Macro (inline-media-image) and unpin > Macro (inline-media-image) channels in the list. > ℹ️ **Note** > ℹ️ In general, any newly selected channel source or type is displayed according to the settings that are currently selected within the Graph Plots toolbar. The duration of data displayed in the trace depends on whether you are reviewing live or captured data. > ℹ️ If your system is live, the duration of the trace is limited initially by the **Live data range **(see [Change the scale of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557215)) or the **Pause Buffer Size** (see [Tracker fundamentals](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344556062)), whichever is shorter (in seconds). If your system is in review mode, it displays the trace for the entire capture duration. ## Customize graph plots To customize the data displayed in the Graph Plots view, first choose your data (see [Change the type of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557152)) and then make sure the desired channels are pinned (see [Manage channels](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557260)). 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](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557188) - [Change the scale of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557215) > ℹ️ **Tip**: To toggle the display of all available Graph Plots toolbar options, click the Show advanced button > Macro (inline-media-image) > ℹ️ > ℹ️ on the right of the toolbar. As you customize your graph plots, see [Graph Plots mouse actions](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557254) to understand how to control the full behavior of the Graph Plots view. ## Manage graph plots After you have added all the desired channels and customized the layout of the Graph Plots view, you may want to: - Lock the current selection of channels using the **Selection Link **button. When deactivated, if you click potential channel sources, channels are not added or removed. - Save the current Graph Plot layout (including pinned channels) or load a previous Graph Plot layout using **Graph Settings**. ### Selection Link > Macro (scroll-tablelayout) | | | | --- | --- | | ![image](media://1087ecc9-9adf-4a90-ac6b-2065d87d5fdb) | When the **Selection Link **is deactivated, selecting or de-selecting channel sources does not add or remove graph channels to the current Graph Plot view.
You can still change the layout of your Graph Plots and the channel modifiers (derivative, magnitude, etc) but not the channels themselves (see [Change the layout of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557188)). | > Macro (scroll-pagebreak) ### Graph settings Graph settings enable you to save and load a specific layout within the Graph Plots view. This includes any channels that are pinned (even if they are not present in the current session) or locked using the **Selection Link** button. It also includes the settings specified within the graph plot modifiers ([Change the type of graphed data](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557152)). Graph settings only apply to the Graph Plot view and are a subset of the overall View settings (see [Customize the Tracker user interface](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344555799)). This means: - You can load different Graph Plot layouts while maintaining the current Tracker 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 AutoSave feature but are included as part of the View settings AutoSave (see [Tracker fundamentals](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344556062)). If you want to use your current Graph Plot layout in the future, use the Graph Settings menu. From here you can open the Manage Graph Settings dialog box, where you can import, save or delete Graph Settings files. > Macro (scroll-pagebreak) **To save a new graph setting:** - On the **Graph Plots** toolbar, click Graph Settings > Macro (inline-media-image) , then click **Manage** and click the Save button. :check_mark: **Tip**: Before saving your graph settings, remember to pin all desired channels in a Graph Plots view. **To load a previous graph setting:** - On the **Graph Plots** toolbar, click Graph Settings > Macro (inline-media-image) and either select from the list or click **Manage** and import the required setting. #### Export data To export the current graph channel data to a CSV file, click the CSV Export button > Macro (inline-media-image) . For more information, see [Exporting data to CSV](https://vicon-help.atlassian.net/wiki/spaces/Tracker43/pages/344557455).
