问题描述
在我的一个项目中，我在一个Window窗体中有两个Zedgraph。我在图表中加载数据，对于zedGraph，使AutoScroll为True。
如果我向左或向右移动第一个图形的水平滚动条，然后第一个图形正在移动拳头水平滚动条移动。现在我想在第一个图形滚动条移动的第二个图形上产生相同的效果。我的项目的代码是下面：
In One of my Project,I have two Zedgraph in the one Window Form.I am loading data in the Graph,for both zedGraph ,Making AutoScroll is True.
if i move Left or Right the Horizontal scrollBar of the First Graph,then the Graph of the First is moving on the move of Fist Horizontal ScrollBar move.Now i want to develop same effect on the Second Graph on the Move of First Graph Scrollbar move.Code of my Project is Below:

推荐答案
使用masterpane，
并在zedgraphcontrol中设置此值：
zedGraphcontrol.IsShowHScrollbar = true;
zedGraphcontrol.IsShowVScrollbar = true;
use masterpane,
and in zedgraphcontrol, set this value :
zedGraphcontrol.IsShowHScrollbar = true;
zedGraphcontrol.IsShowVScrollbar = true;
