The following graphs/plots need to be clear and professionally done. The work needs to be done before this Friday. I am using grapher by Golden software. The plots contain too many (up to 9) curves: some of them coincide with the axes or other curves. It is advisable to reduce a number of curves in the plots; the curves should be labelled more clearly, e.g., by the integers of letters.
How can this be done? (Tasks)
(Best) Modify the graphs yourself and I would provide the data. It means you have grapher version 9.
(Acceptable) Suggest what could be done on each graph to make it clear and understandable. These suggestions has to be doable on grapher and can be easily done.
