C++ Qt Charts Examples

Can you show me some examples of using Qt Charts in C++?

Sure! Qt Charts is a great module for creating interactive charts in C++. What type of chart are you interested in?

I'm interested in line charts. Do you have a simple example?

Absolutely! Here's a basic example of a line chart in C++ using Qt Charts:

#include <QtCharts/QChartView>
#include <QtCharts/QLineSeries>

using namespace QtCharts;

QLineSeries *series = new QLineSeries();
series->append(1, 1);
series->append(2, 3);
series->append(3, 2);

QChart *chart = new QChart();
chart->addSeries(series);
chart->createDefaultAxes();

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

That looks great! How do I display this chart in a Qt application?

To display the chart, you can add the QChartView to your main window or widget layout. Here's a quick example:

QMainWindow window;
window.setCentralWidget(chartView);
window.resize(800, 600);
window.show();

Thanks! Can you explain how to customize the chart's appearance?

Certainly! You can customize the chart's title, colors, and axes labels. For example:

chart->setTitle("My Line Chart");
series->setColor(Qt::blue);
chart->axes(Qt::Vertical).first()->setTitleText("Y Axis");
chart->axes(Qt::Horizontal).first()->setTitleText("X Axis");
