QCustomPlot - scale every axis individually

[kb91]

I have developed quite good working scada app.

I would like to have a feature that every graph is scalled individually.

I have tried by adding indixidual y axis for every graph, but I found difficulty later to set scale factor.

  QCPAxis *ax =  ui->customPlot->axisRect()->addAxis(QCPAxis::atLeft);
  //ax->setVisible(false);
  ax->setRange(INIT_Y_MIN, INIT_Y_MAX);
  scaleRatios.insert(scaleRatios.begin()+num,1.0);
  connect(ui->customPlot->yAxis, SIGNAL(rangeChanged(QCPRange)), ax, SLOT(setRange(QCPRange)));
  scaleAxes.insert(scaleAxes.begin()+num, ax);

  ui->customPlot->addGraph(axisX,ax);

Any suggestions how to solve that?

Best regards,
Chris
