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:
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).
