title: JPGraph - Bar Graphs are not showing values
body: <p>I'm using the latest version of JPGraph and I'm trying to alter the graph_api file to show values on Group Bar Plots.  Here's a snippet of code to show my alterations (for those looking at the API, this is in the graph_group function):</p>
  
  <pre><code>$tot = new BarPlot( array_values( $total ) );
  $tot-&gt;value-&gt;show();
  $tot-&gt;value-&gt;SetFormat('%2d');
  $tot-&gt;value-&gt;SetColor('black','black');
  $tot-&gt;value-&gt;SetFont($t_graph_font,FS_BOLD,9);
  $tot-&gt;SetFillColor('lightblue');
  $tot-&gt;SetWidth(0.7);
  $tot-&gt;SetLegend( lang_get( 'legend_total' ) );
  $graph-&gt;Add($tot);
  
  $p1 = new BarPlot( array_values( $p_metrics['open'] ) );
  $p1-&gt;SetFillColor( 'yellow' );
  $p1-&gt;SetWidth( 1 );
  $p1-&gt;SetLegend( plugin_lang_get( 'legend_opened' ) );
  $p1-&gt;value-&gt;show();
  $p1-&gt;value-&gt;SetColor('white','white');
  $p1-&gt;value-&gt;SetFormat('%2d');
  $p1-&gt;value-&gt;SetFont($t_graph_font,FS_BOLD,8);
  $p1-&gt;SetFillColor('red');
  $p1-&gt;SetLegend( lang_get( 'legend_still_open' ) );
  
  $p2 = new BarPlot( array_values( $p_metrics['closed'] ) );
  $p2-&gt;SetFillColor( 'blue' );
  $p2-&gt;SetWidth( 1 );
  $p2-&gt;SetLegend( plugin_lang_get( 'legend_closed' ) );
  $p2-&gt;value-&gt;show();
  $p2-&gt;value-&gt;SetFormat('%2d');
  $p2-&gt;value-&gt;SetColor('black','black');
  $p2-&gt;SetFillColor('forestgreen');
  $p2-&gt;SetWidth(0.5);
  $p2-&gt;SetLegend( lang_get( 'legend_closed' ) );
  
  $gbplot = new GroupBarPlot( array( $p1, $p2 ) );
  $gbplot-&gt;value-&gt;show();
  
  $graph-&gt;Add( $gbplot );
  </code></pre>
  
  <p>According to the API, using "value->show()" should display the values.  When I add in that last line (for $gbplot), the graph doesn't show.  If I comment it out, the graph will display sans values.  What am I missing?</p>
