title: Jpgraph wont change colors on my barplot
body: <p>I'm just getting started with jpgraph and XAMPP I was looking to make a barplot.
  As I was reading some articles on the web it said you could pass in an array of colors to setfillcolor so that each bar would be a different color. However whenever I pass it color the graph won't change from its default color of light blue.</p>
  
  <p>The graph respond s to changes in data but not changes to color.
  I tried with an accumulated bar graph example and that seems to be color responsive.</p>
  
  <p>I'm not sure how to diagnose a problem like this. Help please!</p>
  
  <p>Code Below(Example from the Jpgraph documentation with color changed from orange to #B0C4DE [orange from the original example doesn't show up]):</p>

  $graph-&gt;yaxis-&gt;scale-&gt;SetGrace(20);
  
  // We don't want to display Y-axis
  $graph-&gt;yaxis-&gt;Hide();
  
  // Now create a bar pot
  $bplot = new BarPlot($datay);
  
  $bplot-&gt;SetFillColor("#B0C4DE");
  //  ALSO tried:

  $bplot-&gt;SetShadow();
  
  //You can change the width of the bars if you like
  //$bplot-&gt;SetWidth(0.5);
  
  // We want to display the value of each bar at the top
  $bplot-&gt;value-&gt;Show();
  $bplot-&gt;value-&gt;SetFont(FF_ARIAL,FS_BOLD,12);
  $bplot-&gt;value-&gt;SetAlign('left','center');

  // Add the bar to the graph
  $graph-&gt;Add($bplot);
  
  // .. and stroke the graph
