  20. $graph->xaxis->scale->SetGrace(20);
  21. // Add a drop shadow
  22. $graph->SetShadow();
  23. // Adjust the margin a bit to make more room for titles
  24. $graph->img->SetMargin(40,30,20,40);
  25. // Create a bar pot
  26. $bplot = new BarPlot($datay);
  27. // Adjust fill color
  28. $bplot->SetFillColor(‘orange');
  29. $bplot->value->Show();
  30. $bplot->value->SetFont(FF_ARIAL,FS_BOLD,10);
  31. $bplot->value->SetAngle(45);
  32. $bplot->value->SetFormat(‘%d');
  33. $graph->Add($bplot);
  34. // Setup the titles
  35. $graph->title->Set(iconv(“UTF-8″, “gb2312″,”用户消费报表图”));
  36. $graph->xaxis->title->Set(iconv(“UTF-8″, “gb2312″,”用户姓名”));
  37. $graph->yaxis->title->Set(iconv(“UTF-8″, “gb2312″,”用户订单数量”));

  40. $graph->title->SetFont(FF_SIMSUN,FS_BOLD);
  41. // Display the graph
  42. $graph->Stroke();
