用C++绘制图形和图表的简单方法？

std::cout << "Hello, World!" << std::endl;

// 创建一个 QChartView

QChartView *chartView = new QChartView(QChart::ChartWithAxes(

    QChart::PrimaryAxis, QChart::AxisPosition::Bottom,

    QChart::SecondaryAxis, QChart::AxisPosition::Left

));

// 创建一个 QLineSeries

QLineSeries *lineSeries = new QLineSeries();

// 添加一些数据

lineSeries->append(1, 2);

lineSeries->append(2, 4);

lineSeries->append(3, 6);

lineSeries->append(4, 8);

// 设置线条样式

lineSeries->setPen(QPen(Qt::blue, 2));

// 将线条添加到图表中

chartView->chart()->addSeries(lineSeries);

// 设置图表标题

chartView->chart()->setTitle("Line Chart Example");

// 设置 X 轴和 Y 轴的标签

chartView->chart()->axisX()->setLabels(QString("X-Axis").split(" ", QString::SkipEmpty()));

chartView->chart()->axisY()->setLabels(QString("Y-Axis").split(" ", QString::SkipEmpty()));

// 设置 X 轴和 Y 轴的刻度标签

chartView->chart()->axisX()->setTickLabels(QString("X-Axis-Tic").split(" ", QString::SkipEmpty()));

chartView->chart()->axisY()->setTickLabels(QString("Y-Axis-Tic").split(" ", QString::SkipEmpty()));

// 设置 X 轴和 Y 轴的刻度值

chartView->chart()->axisX()->setTickCount(5);

chartView->chart()->axisY()->setTickCount(5);

// 设置 X 轴和 Y 轴的参考线

chartView->chart()->axisX()->setReferenceLines(QValueAxis::create(chartView->chart()->axisX()));

chartView->chart()->axisY()->setReferenceLines(QValueAxis::create(chartView->chart()->axisY()));

// 设置 X 轴和 Y 轴的参考线颜色

chartView->chart()->axisX()->setLineColor(Qt::red);

chartView->chart()->axisY()->setLineColor(Qt::green);

// 设置 X 轴和 Y 轴的参考线宽度

chartView->chart()->axisX()->setLineWidth(2);

chartView->chart()->axisY()->setLineWidth(2);

// 设置 X 轴和 Y 轴的参考线间距

chartView->chart()->axisX()->setTickLength(5);

chartView->chart()->axisY()->setTickLength(5);

// 设置 X 轴和 Y 轴的参考线标签

chartView->chart()->axisX()->setTickLabelFont(QFont("Arial"));

chartView->chart()->axisY()->setTick
