1. Function and data plots with Gnuplot
    Use the Code editor's Gnuplot mode for classic function plots — axes, styles, and multiple curves — exported as a publication figure.
  2. Plotting your data
    Feed measured values into Gnuplot inline, pick columns with `using`, and style points and lines like the journals expect.
  3. Print polish and multiplot
    Ranges, tics, key placement, and two panels in one figure — the finishing pass that makes a Gnuplot chart journal-ready.
