How can I visualize data using C++ and Qt?

You can use the Qt Charts module to create various types of charts like line, bar, and pie charts. Would you like a code example?

Yes, please provide a simple example of a line chart.

Sure! Here's a basic example:

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

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);

This will create a simple line chart. Do you need help with anything else?

How do I add labels to the axes?

You can set the axis titles using the setTitle method. For example:

chart->axes(Qt::Horizontal).first()->setTitleText("X Axis");
chart->axes(Qt::Vertical).first()->setTitleText("Y Axis");

This will label your axes. Would you like to know more about customizing the chart?

Yes, how can I change the color of the line?

You can change the color of the line by setting the pen of the series. For example:

QPen pen;
pen.setColor(Qt::red);
series->setPen(pen);

This will change the line color to red. Let me know if you have more questions!
