Chart not updating

[raketmus]

I have a qchart

   chart = new QChart();
   series->append(QDateTime::currentDateTime().toMSecsSinceEpoch(), 20.00);
   series->append(QDateTime::currentDateTime().toMSecsSinceEpoch() + 900, 25.00);
   chart->addSeries(series);
   chart->setTitle("Tempature since 0:00");
   axisX = new QDateTimeAxis;
   axisX->setTickCount(10);
   axisX->setFormat("hh:mm:ss");
   axisX->setTitleText("Time");
   chart->addAxis(axisX, Qt::AlignBottom);
   series->attachAxis(axisX);

   axisY = new QValueAxis;
   axisY->setLabelFormat("%i");
   axisY->setTitleText("Tempature");
   chart->addAxis(axisY, Qt::AlignLeft);
   series->attachAxis(axisY);
   chartView = new QChartView(chart);
   chartView->setRenderHint(QPainter::Antialiasing);

which i want to update in a timeout fuction for a timer the thing is it is not updating after appending series i can make it update the chart it self by removeing and adding the series but this does not update the axis how do i do this

@raketmus I don't see any timers in the code you posted. How do you update in the timeout slot?

I have figured out my problem i was not updating min and max values for the axises.
The documentation should really include this in every example seeing how hard this was to find out.
