How can I bind data to charts in Qt using C++?

You can bind data to charts in Qt by using the QChart and QLineSeries classes. First, create a QLineSeries object and add data points to it. Then, create a QChart object and add the series to it. Finally, set the chart view to display the chart.

Can you show me a code example for that?

Sure! Here's a simple example:

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

using namespace QtCharts;

QLineSeries *series = new QLineSeries();
series->append(0, 6);
series->append(2, 4);
series->append(3, 8);

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

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

What if I want to update the chart dynamically?

To update the chart dynamically, you can modify the data in the QLineSeries and call the chart->update() method to refresh the display. You can also use a timer to periodically update the data.

Are there any specific libraries I need to include?

Yes, you need to include the Qt Charts module in your project. Make sure to add QT += charts in your .pro file.
