Graphic representation example.

.

VRmaze provides a graphing system to format various sets of digital data. This numerical data can come from various sources such as DataRecords, mathematical functions or even audio curves.

Interest of the graph system

The interest of the graph system is to offer a visualization of a dataset that would be complex to visualize in another form.

Interface

The graphical viewer allows an interaction with the mouse:

Interaction	Consequence
Drag and drop + right mouse button	Lateral move
Key A on keyboard	Frame
Mouse wheel	Zoom +/-
Drag and drop + mouse wheel button	Interactive Zoom
Drag and drop + left mouse button on a curve	Curve information under the mouse

The toolbar

The graphical viewer provides access to a productivity toolbar.

• Display the table of values
• Export values in .csv format
• Export to pdf format
• Export to png
• Zoom in / out
• Show / hide the grid
• Create a new independent viewing window
• Extract a new dataset by interactive selection

Tool Accessibility

Some tools in the toolbar are only accessible depending on the type of graph displayed or the entity selected in the protocol tree.

Advanced functions of the graphic viewer

Animation curves

Possible interaction on an animation curve.

The graphic viewer offers some interaction functions within the graphic itself, for example it is possible to change the appearance of an animation curve by changing the values of the animation keys directly in the window.

Animation of properties

Property animation is an advanced VRmaze concept described [here] (../animation/animatedProperty.md).

Annotations

Example annotations

.

Annotations are a system for adding information to graphics from DataRecords data sets. These annotations can be created and modified dynamically in the graph viewer.

Saving annotations

Annotations are saved in the protocol file.

Delete annotations

Annotations cannot be deleted from the viewer, but can be deleted from the protocol tree.

Dataset Formatting

The formatting of a dataset of type DataRecord provided by default may not be ideal. VRmaze provides a graphical extension system that allows the data to be viewed in another graphical form.

Some examples of graphics that can be made in VRmaze:

Spatial representation (X graph = X position; Y graph = Y position).

Colored spatial representation as a function of time (X graph = X position; Y graph = Y position, color = Timecode).

Heat map representation of time spent in each area.

Saving Graphs

The graphs are saved in the protocol file.
