Scatter plots (aka scatter graphs, or scatter diagrams) is a graph that plots two variables to see how they are related. The relationship between these two variables can be linear (ie. y = mx + b) or non linear (ie. y = x^2).
Below are some examples of scatter plots using POWER BI. The graphs are interactive and you can slice the data by team or player position. Scrolling over the data points will give you information about the player such as salary, goals, assists, points, and earnings per point. We can see that there is a a fairly weak relationship between goals scored and salary. There is also a color saturation applied on the points scored (higher points, darker color). You can expand the graph below at the bottom.
Scrolling over the highest data point, we can see that Tuomo Ruutu got paid $5MM per point in his 2015/2016 NHL season! The above scatter plots only shows data for players who had at least one point.
