msChart组件安装与编程

首先下载mschart.ocx文件，至于它所依赖的.net环境，网上有很多,本人下载的插件给出链接，http://www.cr173.com/soft/47300.html而它所依赖的环境可以从我的云盘中下载http://pan.baidu.com/s/1dETjpvj

安装好后可以通过(1)regedit注册表查看一下是否安装成功。然后注册插件：regsvr32 +path+mschart.ocx 注意：以管理员运行cmd。(2)还可以通过vs编译器查看是否存在第三方插件：打开vs-->tool-->toolbox--->com。查找

勾选就可以在vs中使用该组件了。以上是mschart的安装。下面来看一下qt环境下的demo.

    QAxWidget *widget = new QAxWidget(this);
    widget->resize(size().width()-10,size().height()-10);
    widget->setControl(QString::fromUtf8("{31291E80-728C-11CF-93D5-0020AF99504A}"));

    pMsChart = new MsChart::_DMSChart(widget->asVariant().value<IDispatch*>());
    pMsChart->SetTitleText("MsChart`s example");//设置标题
    //设置背景颜色
    pMsChart->Backdrop()->Fill()->SetStyle(MsChart::VtFillStyleBrush);
    pMsChart->Backdrop()->Fill()->Brush()->FillColor()->Set(120,120,120);
    //设置SeriesType
    pMsChart->setChartType(MsChart::VtChChartType3dArea);//饼图
//    pMsChart->SetSeriesType(MsChart::VtChSeriesType2dLine);//2dLine
    pMsChart->SetColumnCount(3);//y轴三条曲线
    pMsChart->SetRowCount(3);//x轴三条曲线

    //显示图例
    pMsChart->SetShowLegend(true);
    pMsChart->SetColumn(1);
    pMsChart->SetColumnLabel("1号机");
    pMsChart->SetColumn(2);
    pMsChart->SetColumnLabel("2号机");
    pMsChart->SetColumn(3);
    pMsChart->SetColumnLabel("3号机");
    //设置x轴
    pMsChart->SetRow(1);
    pMsChart->SetRowLabel("9.1");
    pMsChart->SetRow(2);
    pMsChart->SetRowLabel("9.2");
    pMsChart->SetRow(3);
    pMsChart->SetRowLabel("9.3");
    //栈模式
    pMsChart->SetStacking(false);
    //y轴设置
    //不自动标注x/y轴刻度
    //设置成true时 y轴会自动根据熟知的额多少对y轴最大值进行修改
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->ValueScale()->SetAuto(false);
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdX)->ValueScale()->SetAuto(false);

    //y轴最大/最小刻度
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->ValueScale()->SetMaximum(200);
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->ValueScale()->SetMinimum(0);
    //y轴刻度等分
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->ValueScale()->SetMajorDivision(5);

    //每刻度一个刻度线
    //y轴
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->ValueScale()->SetMinorDivision(1);
    //x轴
//    pMsChart->Plot()->Axis(MsChart::VtChAxisIdX)->ValueScale()->SetMinorDivision(1);

    //y轴名称
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->AxisTitle()->SetText("Hours");
    //x轴名称
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdX)->AxisTitle()->SetText("Time");
    //y轴名称的排列方式
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->AxisTitle()->TextLayout()->Orientation(/*1*/);
    //线色
    pMsChart->Plot()->SeriesCollection()->Item(1)->Pen()->VtColor()->Set(0,0,255);
    pMsChart->Plot()->SeriesCollection()->Item(2)->Pen()->VtColor()->Set(0,255,0);
    pMsChart->Plot()->SeriesCollection()->Item(3)->Pen()->VtColor()->Set(255,0,0);
    //线宽(对点位图有效)
//    pMsChart->Plot()->SeriesCollection()->Item(1)->Pen()->SetWidth(10);
//    pMsChart->Plot()->SeriesCollection()->Item(2)->Pen()->SetWidth(20);
//    pMsChart->Plot()->SeriesCollection()->Item(3)->Pen()->SetWidth(30);
    //设置隐藏第二Y轴不可用
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdY2)->AxisScale()->SetHide(true);
    //设置数值
    pMsChart->DataGrid()->SetData(1,1,57,0);
    pMsChart->DataGrid()->SetData(2,1,100,0);
    pMsChart->DataGrid()->SetData(1,2,100,0);
    //pMsChart->Plot()->SeriesCollection()->Item(1)->SetSecondaryAxis(false);
    //数据点类型显示数据值的模式(对柱状图和点线图有效)
    //0表示不显示。1显示柱状图。2显示在柱状图内上方。3显示在柱状图内中间。4显示在柱状图内下方
    pMsChart->Plot()->SeriesCollection()->Item(1)->DataPoints()->Item(-1)->DataPointLabel()->SetLocationType(MsChart::VtChLabelLocationTypeAbovePoint);
    pMsChart->Plot()->SeriesCollection()->Item(2)->DataPoints()->Item(-1)->DataPointLabel()->SetLocationType(MsChart::VtChLabelLocationTypeAbovePoint);
    pMsChart->Plot()->SeriesCollection()->Item(3)->DataPoints()->Item(-1)->DataPointLabel()->SetLocationType(MsChart::VtChLabelLocationTypeAbovePoint);
    //不要与x轴垂直的表格线
    pMsChart->Plot()->Axis(MsChart::VtChAxisIdX)->AxisGrid()->MajorPen()->SetStyle(MsChart::VtPenStyleNull);

    pMsChart->Refresh();//更新插件

效果图如下：

想要改变样式：改变setChartType的值即可。
