How can I adapt my chart size according to my datas?

[deleted286]

I have a scrolling dynamic chart. When the new data come, i cannot see because the chart size. Can i automatize it ? Does qt charts have a property like that?

QChart *chart = new QChart();
 chart->addSeries(series);
 qDebug()<< series;
 QPen green(Qt::red);
 green.setWidth(2);
 series->setPen(green);
 chart->legend()->hide();
 chart->setTitle("deneme");
 chart->setAnimationOptions(QChart::AllAnimations);




 QValueAxis *axisX=new QValueAxis;
 axisX->setTickCount(10);
 chart->addAxis(axisX, Qt::AlignBottom);
 series->attachAxis(axisX);

 QValueAxis *axisY = new QValueAxis;
 axisY->setTickCount(5);
 chart->addAxis(axisY, Qt::AlignLeft);
 series->attachAxis(axisY);

 QChartView *chartView = new QChartView(chart);
 chartView->setRenderHint(QPainter::Antialiasing);

 this->setCentralWidget(chartView);

There are datas on the right but we cannot see

Set the range of your X-Axis so that your line series fits in completely

@Pl45m4 Can we do it automatically?

I don't know... Can you?! It's your project :)
You know best where you add new data and where you can insert the code to rearrange your axis.

Maybe this helps:
