Plotting statistical data

Once you have entered your data, selected the data set to analyze and specified your fit model, you can plot your data. You can plot up to five scatter plots at a time.

1.In Symbolic view, select the data sets you want to plot.

2.Make sure that the full range of your data will be plotted. You do this by reviewing (and adjusting, if
