[Ext JS 4] 实战之Chart 坐标控制（单坐标，双坐标）
前言
在Extjs 中， 单一的 Column Chart 的展示效果如上。
定义的步骤如下：
1. 创建一个 Ext.chart.Chart
2. 创建两个坐标轴， axes
一个 Category 类型的横坐标用来显示日期
一个Numeric 类型的纵坐标用来显示数据
3. 配置显示的图 series
配置 column 类型的柱状图。
具体代码如下：

</html>如何设置坐标轴的长度
针对上面的例子， 坐标轴的长度是Extjs根据数据大小自动运算并设置的。
如果需要手动定义这个长度的话，改如何设置呢？
对于Numeric这样的坐标轴来说， 有maximum 和 minimun 这样的参数可以配置。
而且配置也很简单了， 就不多介绍了。
这里只是对红色的部分做一个伏笔（这种设置对于配置 堆叠的图形不使用）
多个图形， 两个纵坐标轴
有的状况下， 可能会使用多个图形，
因为图形的范围不同，可能需要使用两个纵坐标轴。
类似的情景可以是这样：
有三个图， 两个柱状图， 一个折线图
折线图和柱状图的数据范围或是单位可能不同。
这里看上去好像是一个折线图和一个柱状图。
其实是有两个柱状图， 只不过一个被另一个盖住了。
出现这种状况的原因是在定义的时候， 往series 中添加了两个column 的chart.
这种状况的源码是：

</html>基本上这不是我们想要的效果。
我们要的效果应该是这样：
这是完美的呈现方式。
完美方式实现的思想是：
1 创建两个坐标轴， axes
一个 Category 类型的横坐标用来显示日期
一个Numeric 类型的纵坐标用来显示柱状图数据一个Numeric 类型的纵坐标用来显示折线图数据
2. series 添加一个 column Chart. stacked.
以上定义完成之后， 会发生基本上都正常， 但是有一点就是， 左右的两个纵坐标的尺度可能不同。
通过配置maximum 和maximum 来设置坐标并不会生效。
这里就要提到上面框出的maximum配置的红色部分了， 因为这个配置对于堆叠的图已经不适用了。
堆叠图性的左右坐标一致
为什么会出现左右坐标不一致的状况， 看一看Extjs 的 Ext.chart.axis.Numeric 的定义
原来是这个地方有限制。这应该是Extjs 有意为之了， 至于原因是什么，尚不可知。
不管这样，先去除这个限制得到想要的效果。
解决方案就是定义一个和 Ext.chart.axis.Numeric 类似的坐标定义
