msChart组件安装与编程

Posted 2020-08-11 first_semon

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.

效果图如下：

想要改变样式：改变setChartType的值即可。
