Embedded Files
One of the ways to edit your visualization in DXR is via the graphical user interface (or GUI for short). Using the GUI, you can modify the vis specs using "click"-based interactions at runtime (e.g., gaze and tap in HoloLens). The GUI is enabled by default but you can enable/disable it in the Inspector window when you click the DXRVis object.
The GUI, shown on the left, is designed to be minimal and intuitive, only allowing modification of the basic properties of the vis spec.
To change any parameter, click on the current value to expose the dropdown menu then click on your selection. The options for the Data parameter are all the valid files in Assets/StreamingAssets/DxRData. The options for the Mark parameter are all the folders containing mark game object prefabs in Assets/DxR/Resources/Marks (during deployment, DXR cheks the list of marks in Assets/DxR/Resources/Marks/marks.json as well). To add a new channel, just click the "Add Channel" button. For each channel, the options for Channel, Data Field, and Data Type are documented in the Grammar Docs. To delete a channel, click the X button on the leftmost side of the channel GUI. The "Update Vis" button in the lowermost part updates the visualization and the vis specs JSON file with the changes in the GUI.
In addition to setting the parameters for the vis specs, the GUI provides some interactive buttons for convenience (see below). These allow runtime view manipulations, in order from left to right: reset view, scale up view (zoom in), scale down view (zoom out), rotate along X axis, rotate along Y axis, rotate along Z axis.
