Hi all, I saw this question posted in another forum. I wish to do the same in Mathematica; the author says he routinely does it, does anyone know how? Thanks in advance, Leo > Good morning. Suppose I have a table of data with multiple columns. The first column has X values, and the second (say) has Y values to be plotted against X. The remaining columns have other data associated with X, but I'm not going to plot those. > > Now suppose I want to plot X against Y, but I want the markers to vary in shape, color, or some other visible characteristic depending on the values of data in columns that I am not plotting. Now granted, I could write a series of loops to parse the data array into smaller arrays, and plot each. But that's a lot of work, and it would be more compact and readable if I could use the other data columns parametrically to set marker characteristics. > > I'm still fairly new to this system, but as a long-time Mathematica user, this is a fairly common thing to do. Is it straightforward in this system? Thanks, my searches have come up short. > > Oh yeah. Ideally, I could create a legend containing each symbol type, even though only only y-series is being plotted. > > Appreciate any help I can get...
