Plot Screenshots: Statistical Box Demo

  QCPStatisticalBox *statistical = new QCPStatisticalBox(customPlot->xAxis, customPlot->yAxis);
  QBrush boxBrush(QColor(60, 60, 255, 100));
  boxBrush.setStyle(Qt::Dense6Pattern); // make it look oldschool
  statistical->setBrush(boxBrush);
  
  // specify data:
  statistical->addData(1, 1.1, 1.9, 2.25, 2.7, 4.2);
  statistical->addData(2, 0.8, 1.6, 2.2, 3.2, 4.9, QVector<double>() << 0.7 << 0.34 << 0.45 << 6.2 << 5.84); // provide some outliers as QVector
  statistical->addData(3, 0.2, 0.7, 1.1, 1.6, 2.9);
  
  // prepare manual x axis labels:
  customPlot->xAxis->setSubTicks(false);
  customPlot->xAxis->setTickLength(0, 4);
  customPlot->xAxis->setTickLabelRotation(20);
  QSharedPointer<QCPAxisTickerText> textTicker(new QCPAxisTickerText);
  textTicker->addTick(1, "Sample 1");
  textTicker->addTick(2, "Sample 2");
  textTicker->addTick(3, "Control Group");
  customPlot->xAxis->setTicker(textTicker);
  
  // prepare axes:
  customPlot->yAxis->setLabel(QString::fromUtf8("O₂ Absorption [mg]"));
  customPlot->rescaleAxes();
  customPlot->xAxis->scaleRange(1.7, customPlot->xAxis->range().center());
  customPlot->yAxis->setRange(0, 7);
  customPlot->setInteractions(QCP::iRangeDrag | QCP::iRangeZoom);
