Triangular Plot

A triangular plot, representing pure cobalt, zinc, and nickel oxides at each of its corners, and oxide compounds of the three elements in its interior, includes one thousand overlapping dots that are color-coded to represent the conductivity of each combination of compounds. The logarithm of the conductivity varies from -2 near the zinc corner to +2 in the vicinity of a point that is a third of the way between the cobalt and nickel corners. This point is labeled as Co2NiO4,

A triangle plot is a triangular shape that three variables which sum to a constant.  This particular triangle plot shows the electrical conductivity for one thousand oxides containing Cobalt, Nickel, and Zinc.  Most of the plots in this graph trend towards Cobalt.
