zedgraph基本教程篇--第六、七节HorizontalBarSampleDemo.cs和StackedBarSampleDemo.cs介绍
第六、七节HorizontalBarSampleDemo.cs和StackedBarSampleDemo.cs介绍
这两节与第五节相比，并没有本质上的区别，所以这里只给出相应的代码、示例图和必要的说明。

这两个图的区别就是基轴不同，一个是以X轴为基轴，一个是以Y轴为基轴，ZedGraph中有相应的属性，很方便的在两个轴之间转换。如下：
myPane.BarBase
=
BarBase.Y;
下面我主要说说myPane.BarType。
BarType是一个枚举，共有六项，分别为Cluster、ClusterHiLow、Overlay、SortedOverlay、Stack和PercentStack。
Cluster和ClusterHiLow是让多个同一个基类Bar依次排开，Cluster还可以使用来自IPointList的“Z”的值来定义每一个Bar的底部。
myPane.BarType
=
BarType.Cluster;或者myPane.BarType
=
BarType.ClusterHiLow;如下图：

Overlay和SortedOverlay故名思意，就是柱形按坐标相互覆盖。不同之处在于Overlay是按照哪个先画哪个在前的原则(注意这里不是按后画把先画的柱形覆盖的原则，而是正好相反按先画在前原则)。
SortedOverlay是按位标的大小，按小的位标在前，大的位标在后的原则来绘图的。
如下两图，第一个是按Overlay，第二个是SortedOverlay。
最后的两个Stack和PercentStack就是按先前的位标依次累积上升。例如有两个坐标为(
0
,
100
), (
0
,
120
)，那么第一个坐标位置就是(
0
,
100
) , 第二个就是(
100
,
220
)。而PercentStack是把相应的坐标转换成百分比来计算坐标位置的。例图可以参看本节的前两个图。
