qt - 如何在 QT 中根据我的数据自动调整图表大小？

Question

我有一个滚动的动态图表。当新数据到来时，我看不到图表大小。我可以自动化吗？qt 图表有这样的属性吗？在此处输入图像描述

void MainWindow::initChartView()
{
    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(5);
    axisX->setRange(0, 2);
    chart->addAxis(axisX, Qt::AlignBottom);
    series->attachAxis(axisX);


    QValueAxis *axisY = new QValueAxis;
    axisY->setTickCount(5);
    axisY->setRange(0,2);
    chart->addAxis(axisY, Qt::AlignLeft);
    series->attachAxis(axisY);

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