In a script intended to plot two sets of data points,
the plotting statement is

plot 'plotII.dat'  w p pt 7 rgb "blue",\
     'plotIII.dat' w p pt 7 rgb "red"

This produces the following error message.

gnuplot> plot 'plotII.dat'  w p pt 7 rgb "blue", 'plotIII.dat' w p pt 7 
rgb "red"
                                     ^
         line 0: unexpected or unrecognized token: rgb

But if I remove the second half, from the comma
onwards, it does plot the first set as blue points.
Why is this, and what should I do?

morning,

you must put a "lc" for linecolor in front of the rgb.

plot 'plotII.dat'  w p pt 7 lc rgb "blue",\
     'plotIII.dat' w p pt 7 lc rgb "red"

Thank you, that works. I wonder why it works for
just one without the lc.

Doesn't work here, neither with 5.4 or 6.0

gnuplot> plot '+' w p pt 7 rgb 'blue'
                            ^
          unexpected or unrecognized token: rgb

or an ancient 4.6

gnuplot> plot '+' w p pt 7 rgb 'blue'
                            ^
          ';' expected

Best, Karl
