首先下載mschart.ocx文件，至於它所依賴的.net環境，網上有很多,本人下載的插件給出鏈接，http://www.cr173.com/soft/47300.html而它所依賴的環境可以從我的雲盤中下載http://pan.baidu.com/s/1dETjpvj
安裝好后可以通過(1)regedit注冊表查看一下是否安裝成功。然后注冊插件：regsvr32 +path+mschart.ocx 注意：以管理員運行cmd。(2)還可以通過vs編譯器查看是否存在第三方插件：打開vs-->tool-->toolbox--->com。查找
勾選就可以在vs中使用該組件了。以上是mschart的安裝。下面來看一下qt環境下的demo.

效果圖如下：
想要改變樣式：改變setChartType的值即可。
