Each XY plot node contains X Type and Y Type sub-nodes to specify what should be plotted along the X and Y axes of the graph, respectively. To plot position along one of the axes, select the corresponding node (either X Type or Y Type) and select Position for the Type property. This will activate the Position node, which has its own properties.
This node defines the data for the axis of this node's parent to come from a direction vector. It is only visible if the Type property of the parent node is set to Position.
Since simulation parts may exist in three-dimensional space while each axis of an XY plot represents only a single dimension, the three-dimensional coordinates of the part being plotted must be reduced to one. This is accomplished by specifying a direction vector indicating how to display the position of each of the sample locations. The dot product of the direction vector at each sample location on the selected parts in a plot is then plotted along the selected axis. The Direction property is specified by selecting the Position node under the X Type or Y Type nodes. For example, in order to plot X coordinates of the selected parts, you would specify a direction vector of [1,0,0].
