title: Gnuplot: draw error bars of data points outside plotting range
body: <p>If I set a specific yrange and plot in a pdf terminal with this plot command:</p>
  
  <pre><code>plot "data.dat" u 1:4:5:6 w yerrorbars pt 6 ps 0.5 t "R_t"
  </code></pre>
  
  <p>errorbars that belong to data points outside the yrange, but end inside the yrange are not shown.
  How do I force gnuplot to draw those. I already tried "set clip one/two"</p>
