title: Gnuplot: how to fill a bar with both a color background and a pattern
body: <p>I want to fill a bar with both a color background and a pattern. Is it possible in Gnuplot?</p>
  
  <p>I am using Gnuplot 4.6.5</p>
  
  <p>The code I have now:</p>
  
  <pre><code># set terminal pngcairo  transparent enhanced font "arial,10" fontscale 1.0 size 500, 350 
  # set output 'histograms.2.png'
  set boxwidth 0.9 absolute
  set style fill   solid 1.00 border lt -1
  set key inside right top vertical Right noreverse noenhanced autotitles nobox
  set style histogram clustered gap 1 title  offset character 0, 0, 0
  set datafile missing '-'
  set style data histograms
  set xtics border in scale 0,0 nomirror rotate by -45  offset character 0, 0, 0 autojustify
  set xtics  norangelimit font ",8"
  set xtics   ()
  set title "US immigration from Northern Europe\nPlot selected data columns as histogram of clustered boxes" 
  i = 22
  set yrange [0:2000]
  set style line 1 lc rgb 'orange';
  set style line 2 lc rgb 'pink';
  plot for [i=2:7] 'data.dat' using i:xtic(1) ti col ls i%2+1;
  </code></pre>
  
  <p>The data file:</p>
  
  <pre><code>Region  Denmark France Demark-Women France-women Demark-man France-men
  1891-1900   1000 1100   500 600 500 500
  1901-1910   1500 1600   1000 600 500 1000
  </code></pre>
