如何在Q3DSurface上设置坐标轴标签？

Question

我尝试通过执行以下操作在 Q3DSurface 上设置轴标签：

#include "mainwindow.h"

#include <Q3DSurface>

using namespace QtDataVisualization;

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent)
{
    Q3DSurface *graph = new Q3DSurface;
    QWidget *widget = QWidget::createWindowContainer(graph);
    setCentralWidget(widget);
    graph->axisX()->setLabels(QStringList{"a", "b", "c"});
}

MainWindow::~MainWindow() {}

但是标签没有显示，有什么提示可以显示吗？

Answer 1

为 QValue3DAxis 设置此属性没有任何作用，因为它会自动生成标签。

Answer 2

我想你想设置轴标题，而不是标签。默认隐藏的标题

#include "mainwindow.h"

#include <Q3DSurface>

using namespace QtDataVisualization;

MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent)
{
    Q3DSurface *graph = new Q3DSurface;
    QWidget *widget = QWidget::createWindowContainer(graph);
    setCentralWidget(widget);

    m_graph->axisX()->setTitle(QStringLiteral("a"));
    m_graph->axisY()->setTitle(QStringLiteral("b"));
    m_graph->axisZ()->setTitle(QStringLiteral("c"));

    m_graph->axisX()->setTitleVisible(true);
    m_graph->axisY()->setTitleVisible(true);
    m_graph->axisZ()->setTitleVisible(true);
}

MainWindow::~MainWindow() {}
