   // $myBarGraph->SetShowLabels(false);  // The default is true. Setting this to false will cause phpBarGraph to not print the labels of each bar.
   // $myBarGraph->SetShowValues(false);  // The default is true. Setting this to false will cause phpBarGraph to not print the values of each bar.
   // $myBarGraph->SetBarBorder(false);   // The default is true. Setting this to false will cause phpBarGraph to not print the border of each bar.
   // $myBarGraph->SetShowFade(false);    // The default is true. Setting this to false will cause phpBarGraph to not print each bar as a gradient.
   // $myBarGraph->SetShowOuterBox(false);   // The default is true. Setting this to false will cause phpBarGraph to not print the outside box.
   // $myBarGraph->SetBarSpacing(20);     // The default is 10. This changes the space inbetween each bar.

   // Add Values to the bargraph..

   $myBarGraph->SetEndBarColor(\"A624A6\");    // This is the color on the bottom of every bar. This is not used when SetShowFade() is set to false.
   $myBarGraph->SetLineColor(\"ffffff\");      // This is the color all the lines and text are printed out with.
