title: How to make dashed / dotted / dash-dotted line in octave?
body: <p>I'd like to create monochrome diagram/graph in octave using <code>plot</code> command. 
  That is why I'd like make different  lines of graphs with using line style, for example dashed/dotted/dash-dotted styles. <strong>Standard <code>plot</code> suggests several styles for line, but none of them looks like listed variants.</strong></p>

  <p><strong>EDIT-1:</strong>
  Standard plot styles are inapplicable for my case: such styles as <code>":"</code>, <code>"-."</code>, <code>"--"</code> don't work, octave draws solid lines in any case. Furthermore, diamonds and squares (<code>d</code> and <code>s</code> options) are ugly and disproportionate big. May be it will be helpful information: I'm using Octave under Windows.</p>

  <p><strong>EDIT-2:</strong> For example, such command <code>plot(A(:,1),A(:,2),"-.dk")</code> gives me such (<strong>inapplicable !!!</strong>) figure</p>

  <p>More specifically I want something like this (in part of line style)
