根据您给的文档内容, 这里是对Qt CustomPlot的一些用方法和特性的:
配置项目文件:
cpp
INCLUDEPATH += /path/to/customplot
LIBS += /path/to/customplot/lib/libcustomplot.so
QMAKE_CXXFLAGS += -std=c++11
对于Windows系统,兴许需要添加库文件:
cpp
LIBS += /path/to/customplot/lib/customplot.lib

添加头文件: cpp
用QCustomPlot类创建图表实例:
cpp
QCustomPlot *customPlot = new QCustomPlot;
设置图表的背景、交互性、语言和字体:
cpp
customPlot->setBackground));
customPlot->setInteractions;
customPlot->setLocale);
customPlot->xAxis->setTickLabelRotation;
customPlot->xAxis->setTickLabelFont.family, 10));
折线图:
cpp
QCPGraph *graph = customPlot->addGraph;
graph->setData;
graph->setPen);
散点图:
cpp
QCPScatterStyle scatterStyle;
scatterStyle.setShape;
scatterStyle.setPen);
scatterStyle.setBrush);
scatterStyle.setSize;
graph->setScatterStyle;
graph->setData;
直方图:
cpp
QCPBars *bars = new QCPBars;
bars->setData;
cpp
customPlot->xAxis->setLabel;
customPlot->yAxis->setLabel;
customPlot->xAxis->setRange;
customPlot->yAxis->setRange;
启用鼠标交互:
cpp
customPlot->setInteractions;
添加数据提示:
cpp
QCPItemTracer *tracer = new QCPItemTracer;
customPlot->addItem;
tracer->setGraph;
tracer->setInterpolating;
tracer->setStyle;
tracer->setPen);
Qt CustomPlot是一个功Neng有力巨大的绘图库,Neng轻巧松集成到Qt应用程序中,用于创建各种类型的图表,并给丰有钱的交互功Neng。通过上述方法,您Neng开头用CustomPlot进行数据可视化和图表绘制。
