I have what is probably a very simple question regarding graphing. I am using the book Geochemical and Biogeochemical Reaction Modeling to learn GWB. In the book there are numerous cases (eg. example 29.2 figure 29.4, and example 30.2 figure 30.3) where the traces for multiple reactions are shown on the same graph (ie reactions with different concentrations). My question is, is there a way to graph multiple modeled scenarios on one graph like is shown in the book? Or do i need to export and use another graphing program? Thanks,
