Graphs are objects that can be used to record, visualize or export data from a simulation. They are very powerful and flexible. The user can select from a multitude of data types applied to specific objects to record. Data is recorded as a data stream (sequential list of data values) that can be visualized in three different ways:

  • Time graphs: a time graph of a single data stream (time vs data stream).
  • X/Y graphs: a graph that combines two data streams (data stream A vs data stream B).
  • 3D curves: a 3D graph that combines three data streams in time (time vs (data stream A, data stream B, data stream C)).
  • Following figure illustrates the graph functionality:

    [Examples of graphs]

    A graph is added to the scene with [Menu bar --> Add --> Graph]. What you see is the three dimensional representation of the graph. If a 3D curve was defined for that graph, that curve is directly visible as can be seen in following figure:

    [A graph object]

    Data streams recorded by a graph can be exported to a *.csv file (Comma Separated Values) that can easily be imported by various applications (e.g. Excel). In the scene, select the graphs you want to export the data from, and select [Menu bar --> File --> Export --> Selected graphs as CSV...]. The unit of exported data streams will be in meters, kilograms, seconds and degrees (or a combination of those).
