Adjusting axis according to coming 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?

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QFile>
#include <QtCharts/QLineSeries>
#include <QTimer>
#include <QTextStream>
#include <QtCharts>
#include <QChart>
#include <QString>
#include <QStringList>
#include <QtCore/QDateTime>
#include <QtCharts/QDateTimeAxis>
#include <QQueue>

    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    initChartView();
    ReadFile();
    connect(m_timer, SIGNAL(timeout()), SLOT(Timer_Slot()));
    m_timer->setInterval(500);
    m_timer->start();
}

void MainWindow::Timer_Slot()
{
    static float q_x=0;
   if(!queue.isEmpty()) {
       double num=queue.dequeue();
       q_x += 0.1;
       series->append(q_x, num);
       chart->update();
       qDebug() << q_x << num;
     }
}

    delete ui;
