Anchor points are points on a graph that indicate the relationship between two variables. They can be used to show the influence of one variable on another. To create anchor points, first create a graph with the two variables you want to explore. Next, add anchor points at specific locations on the graph. The point at which both variables are equal is called the origin. Next, change the value of one variable to a new value and change the value of the other variable to that new value. This will change the relationship between those anchor points. To see how this works, use a Venn diagram to display both sets of data in different colors. The blue circles represent data from which anchor points were created, while red circles represent data from which those anchor points were changed. You can also see how each set changes when different values are assigned to each variable.
