Qt4中学习使用QtCharts绘制折线图

一、实例编写环境

二、涉及内容

三、实例效果

四、关键代码

 QLineSeries* series = new QLineSeries();
 series->append(0, 6);
 series->append(2, 4);
 series->append(3,1);
 series->append(4,5);
 series->append(5,2);
 series->append(6,2);
 series->append(7,12);
 series->append(8,2);
 series->setName(QString::fromLocal8Bit("折线"));
 
 QValueAxis  * xAxis = new QValueAxis;
 QValueAxis  * yAxis = new QValueAxis;

view->chart()->setTheme(QChart::ChartThemeBlueCerulean);
 view->chart()->addSeries(series);
 view->chart()->createDefaultAxes();
 view->chart()->setAxisX(xAxis,series);
 view->chart()->setAxisY(yAxis,series);
 view->setRubberBand(QChartView::HorizontalRubberBand);
 view->chart()->setTitle(QString::fromLocal8Bit("绘制折线图"));

五、示例文件获取
