title: gnuplot dashed lines in aqua terminal
body: <p><img src="https://i.stack.imgur.com/nOYTo.png" alt="enter image description here">I am using gnuplot 4.4 patchlevel 4 on Mac OS X v10.6.8.  I'm running a gnuplot script, a simplified version of which is this:  (file1, file2,...etc are specified in the terminal before running the script)</p>
  
  <pre><code>reset
  set term aqua enhanced font "Times-Roman, 18"
  set term aqua dashed
  plot file1 u 3:10 w lines lt 1 linecolor rgb "#FF0000",\
       file2 u 3:10 w lines lt 1 linecolor rgb "#00FF00",\
       file3 u 3:10 w lines lt 1 linecolor rgb "#0000FF",\
       file4 u 3:10 w lines lt 1 linecolor rgb "#FF00FF",\
       file5 u 3:10 w lines lt 1 linecolor rgb "#00FFFF",\
       file6 u 3:10 w lines lt 2 linecolor rgb "#FF0000",\
       file7 u 3:10 w lines lt 2 linecolor rgb "#00FF00",\
       file8 u 3:10 w lines lt 2 linecolor rgb "#0000FF",\
       file9 u 3:10 w lines lt 2 linecolor rgb "#FF00FF",\
       file10 u 3:10 w lines lt 2 linecolor rgb "#00FFFF"

  <p>files 1-5 are one data set and files 6-10 are another. I would like files 1 through 5 to be plotted with solid lines and files 6 through 10 to be plotted with dashed lines.  Is there any way to do this in aqua terminal? According to the built-in help, "lines can be drawn either solid or dashed".  I've looked at multiple faqs and docs but the consensus seems to be that it is really difficult or impossible to do?  Additionally, does anyone know of any comprehensive documentation on the aqua terminal or on gnuplot commands in general?</p>
  
  <p><strong>Edit:</strong> To plot files 6-10 I have been using lw 6 to distinguish them from the 1-5 since I couldn't get dashed lines to work.  Would the script above as I have it do this correctly?  In other words, is the script doing what I think it is doing? (plotting 1-5 solid lines and 6-8 thicker lines?) I ask because in an attempt to make dashed lines, I replace "lw 6" with "lt 2".  This however results in file5 being plotted with dashed lines which is just weird.</p>
  
  <p><strong>Edit 2:</strong> I attached my terminal test graphic and there doesn't seem to be any mention of dashed lines?</p>
  
  <p><strong>Edit 3:</strong> Updated script to reflect changes made.</p>
  
  <p><strong>Edit 4:</strong> Graphic is now of set term aqua enhanced font "Times-Roman, 18" dashed; test</p>
