title: gnuplot, splot, 3D lines, can i suppress the automatic grid?
body: <p>I have a datafile with many blank-line separated blocks of data. The first column is equal in all blocks. Each block of data represents a curve. I want the curves as lines, but because the first column is equivalent across the blocks, gnuplot connects the curves to a surface. I cant figure out how to suppress that behaviour. Maybe someone knows a way? This is my command so far:</p>
  
  <p><code>splot 'bw_rfEvJ.dat' every 2:5:1:1:200:150 u 1:3:(($2/10)**2) w l lt 3 ,\
        'pt_rfEJ.dat' every 2:5:1:1:200:150 u 1:3:(($2/100)**2) w l lt -1 ,\</code></p>
  
  <p>Here, only the second datafile has the equivalent-first-column-structure described above, the first file does not, and the lines come out fine. </p>
  
  <p>Cheers /J</p>
