Objective: plot a graph from data drawn from two arrays. I would like to have the data points marked with a symbol (point, circle, or diamond, etc.) on the graph. How do I do that? Following is the code: -- two arrays of data point: engineeringStress and epsilon(engineering strain) -- Zip is used to put two arrays into data points (x,y) to create stressStrainData -- plot is used to graph The plot shows a line; I would like to have the data points marked (visibly seen) on the graph. Thanks. --mdc > restart; > with(plots); with(plottools); > crossArea := (3.2*19.1)*(1/1000)^2; > force := Array([0., 1380.0, 2780.0, 5630.0, 7430.0, 8140.0, 9870.0, 12850.0, 14100.0, 14340.0, 13830.0, 12500.0]); > engineeringStress := force/crossArea; II.
