Hello, This is on Ubuntu Hardy running gnuplot ver. gnuplot 4.2 patchlevel 2. I have a data file that I am plotting. Here is an exampe: $> cat inputdata.txt 1.83691e-16 3.00000e+00 -2.00000e+00 1.00000e+00 -2.12132e+00 2.12132e+00 -2.92893e-01 1.12500e+00 -3.00000e+00 3.67382e-16 -1.00000e+00 1.25000e+00

3curves.gplt ########################### set parametric #set multiplot set palette rgb 33,13,10 #set view map set xrange [-10:10] set yrange [-10:10] set cbrange [1:4] #set colorbox vertical set

################################################################# If I give the following command on the terminal to plot that datafile: $> gnuplot -persist 3curves.gplt I notice that if I give the
