Creating Line Charts
Note: This is part of the Charts with Widgets Gallery example.
To create a line chart, a QLineSeries instance is needed. Let's create one.
auto series = new QLineSeries;
Then we add data to the series. We can use the append() member function or use the stream operator.
To present the data on the chart we need a QChart instance. We add the series to it, create the default axes, and set the title of the chart.
auto chart = new QChart; chart->legend()->hide(); chart->addSeries(series); chart->createDefaultAxes(); chart->setTitle("Simple Line Chart");
The chart is ready to be shown.
