九、chart控件的使用（图表数据的展示）

chart属于老插件网上还有新的插件功能也更多）

　　Chart控件是VS自带的控件，只是比较老了，功能肯定不如现在出来的某些插件强，不过对于简单的显示还是够用；那么现在来看看chart控件的使用方法：

　　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。
