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()-,size().height()-);
     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(,,);
     //设置SeriesType
     pMsChart->setChartType(MsChart::VtChChartType3dArea);//饼图
 //    pMsChart->SetSeriesType(MsChart::VtChSeriesType2dLine);//2dLine
     pMsChart->SetColumnCount();//y轴三条曲线
     pMsChart->SetRowCount();//x轴三条曲线

     //显示图例
     pMsChart->SetShowLegend(true);
     pMsChart->SetColumn();
     pMsChart->SetColumnLabel("1号机");
     pMsChart->SetColumn();
     pMsChart->SetColumnLabel("2号机");
     pMsChart->SetColumn();
     pMsChart->SetColumnLabel("3号机");
     //设置x轴
     pMsChart->SetRow();
     pMsChart->SetRowLabel("9.1");
     pMsChart->SetRow();
     pMsChart->SetRowLabel("9.2");
     pMsChart->SetRow();
     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();
     pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->ValueScale()->SetMinimum();
     //y轴刻度等分
     pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->ValueScale()->SetMajorDivision();

     //每刻度一个刻度线
     //y轴
     pMsChart->Plot()->Axis(MsChart::VtChAxisIdY)->ValueScale()->SetMinorDivision();
     //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(/**/);
     //线色
     pMsChart->Plot()->SeriesCollection()->Item()->Pen()->VtColor()->Set(,,);
     pMsChart->Plot()->SeriesCollection()->Item()->Pen()->VtColor()->Set(,,);
     pMsChart->Plot()->SeriesCollection()->Item()->Pen()->VtColor()->Set(,,);
     //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(,,,);
     pMsChart->DataGrid()->SetData(,,,);
     pMsChart->DataGrid()->SetData(,,,);
     //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()->DataPoints()->Item(-)->DataPointLabel()->SetLocationType(MsChart::VtChLabelLocationTypeAbovePoint);
     pMsChart->Plot()->SeriesCollection()->Item()->DataPoints()->Item(-)->DataPointLabel()->SetLocationType(MsChart::VtChLabelLocationTypeAbovePoint);
     pMsChart->Plot()->SeriesCollection()->Item()->DataPoints()->Item(-)->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。
