Some time ago, the project was developed using a histogram, pie chart, because there is no good control on the side of the Internet, search on the web, and found that the evaluation of the chart control is quite high, first of all, the installation step, first have to install. NET Framework 3.5sp1, the MSChart.exe is installed mschart_visualstudioaddon.exe,vs2010 the corresponding VS2008 installation. After installing the VS software, you can see the chart control in the data class Control library and drag it over.
Mainly accept the meaning of some properties, lest not to learn again, time wasted
