How to create a Stiff Diagram in Origin

This video demonstrates how to create a Stiff Diagram in Origin 2021b. Stiff diagrams are useful in the analysis of groundwater ion concentration. It plots milli-equivalent concentrations of cations on the left side of the diagram and of anions on the right. Each ion is plotted as a point, and the points are connected to form a polygonal shape.
