一、效果示意

最终程序运行效果如图

点击开始，将随机生成的两组数据添加进折线图里，chart1和chart2 只显示10个数，超过10个数将第一个传进来的数删掉

chart3是将chart1和chart2 的所有数据显示，两条不同的Y轴。

勾选框可以选择chart只显示其中一条线

二、原理说明

点击开始后，timer_tick定时器开始运行，生成两个随机数（速度和距离），添加进两个泛型数组和队列里，

泛型数组每生成新数据就添加进去，队列保持十个数，超过就将先进来的数删掉（FIFO），使表一显示距离队列，表二显示速度队列，表三显示距离和速度的泛型数组。

再添加checkedListBox勾选框，根据是否选中更改表三显示内容

关键点。使用timer定时器生成随机数，调用方法类
