Re: Varying plot symbols according to additional

data = RandomReal[{0, 1}, {15, 4}] // Sort;

For example, let data represent {x, y, marker size, marker hue}

  Line[data[[All, {1, 2}]]],
     Disk[#[[1 ;; 2]],
      Max[#[[3]]/40, .006]]} & /@
 Frame -> True]

Hi all,

I saw this question posted in another forum. I wish to do the same in
the author says he routinely does it, does anyone know how?

Thanks in advance,


> 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.

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
