Research Skills 1: Using SPSS 20: Handout 3, Producing graphs: Page 1: Using SPSS 20, Handout 3: Producing graphs: 3. Line graphs: Line graphs are just as easy to produce. Click on "Graphs.." then "Line.." and then on the picture for "Simple Line" if you want a graph with one line on it, or "Multiple Line" if you want more than one line.

Usually, you would plot predictor variables on the x-axis and y-axis and the response variable on the z-axis.
16/12/2010 · This tutorial for EC3115 shows students how to generate a line graph with two variables and how to add a second Y axis with a different measurement scale.
Reduce a given linear equation in two variables to the standard form y = mx + c; calculate gradients and intercepts of the graphs and then plot them to check.
