kVariable Assignment

The variable assignments available on the Solutions tab vary depending on the graph type selected in the Graph Editor. Some graph types have preset assignments for the independent, x-axis, and y-axis variables. If the value is preset for the current graph type the value will still be displayed on the Solutions tab, but you will not be able to change it. The possible assignments for each graph type are shown in the tables below.
