title: Texture in barplot for 7 bars in R?
body: <p>I have 7 different categories per each value in X. I am using barplot to plot these categories. Such graph looks fine in colors printer, but what if I want it to be fine in black &amp; white. You can check the graph below. I want to have different colors texture, so the graph looks good in color and black &amp; white printer.</p>

  <p>I used densities = c(10,30,40,50,100,60,80) for density parameter in barplot function. Are there any other ways to do different texture in barplot? </p>
  
  <p>Note: I tried the angle value in barplot. However, it isn't a good solution in that case, since not all bars have high values (i.e height of the bar).</p>
