Scatter Diagram: Explanation, Types with Examples and Plots Interpretation of Scatter Diagrams. The Scatter Diagrams between two random variables feature the variables as their x and y-axes. We can take any variable as the independent variable in such a case (the other variable being the dependent one), and correspondingly plot every data point on the graph (x i,y i).The totality of all the plotted points forms the scatter diagram. What is a Scatter Diagram? Scatter Plot Graphs | ASQ Also called: scatter plot, X-Y graph. The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a line or curve. The better the correlation, the tighter the points will hug the line.
