关于微软C#中的CHART图表控件的简单使用
最近公司项目要用到Chart图表控件，这是一个比较老的东西了，目前网络上似乎已经不太流行这个控件，但是只要配置了相关的属性，效果还是可以的。前前后后摸索了好久，接下来谈谈这个件控件最重要的几个属性。
1.ChartAreas属性
ChartAreas属性指绘图区，一个控件可以有多个绘图区，比如我要在同一个控件内显示饼图和柱状图，肯定不能放在同一个ChartAreas区域内，应该在同一个Chart控件里增加两个ChartAreas并分别绑定Series对象。所以ChartAreas属性对应的是一个集合。
2.Series属性
Series属性就是各种图表的图形啦，比如我们要显示某月的天气变化，那么应该有这样两组数据，一组是天数，一组是每天对应的温度值，同时绑定到Series对象中，再将Series对象Add()到Chart控件的Series属性里即可。为了横向比较，例如我要看本月与上月的天气曲线变化图，并同时显示在同一个ChartAreas中，那该怎么办呢？很简单，再实例一个Series对象，将上月的天数数组与温度值数组绑定到一个新的Series2实例中，再将Series2实例Add()到Chart控件的Series属性里，此时，Chart控件的第一个绘图区ChartArea里就会有两条曲线。
3.Legends属性
Legend就是指一个图标的图例，当一个Series属性有多个Series时，或是一个Series有几组数据时，为了区分各自的颜色，通常每个Serie对象一种颜色，这就需要用到图例来指明哪个颜色的代表的是什么数据。如下图所示：
4.关于数据的绑定
将要显示的X轴和Y轴的数据分别放到两个数组里在， 然后绑定即可。
cht1.Series[0].Points.DataBindXY(x, y);
