[Cacti手册译文]--Chapter 6. Graph Overview{第6章.绘图概要}
Almost everything in Cacti is somehow related to a graph. At any time, you can list all available graphs by clicking on the Graph Management menu item. While it is possible to manually create graphs through this screen, new users should follow the instructions provided in the next chapter for creating new graphs in Cacti.
{在Cacti中，几乎每一件事都“莫名其妙”的与图形相关。在任何时候，你能通过点击“图形管理”菜单项来列出所有可用图形。在此屏中可能手工建立图形，一个新的用户应按后面章节来创建一个新图。}
For users that are familiar with RRDTool 1, you will immediately recognize that a graph in Cacti is closely modeled after RRDTool’s graphs. This makes sense since Cacti provides a user friendly interface to RRDTool without requiring users to understand how RRDTool works.With this in mind, every graph in Cacti has certain settings and at least one graph item associated with it. While graph settings define the overall properties of a graph, the graph items define the data that is to be represented on the graph. So the graph items define which data to display and how it should displayed, and also define what should be displayed on the legend.
{对于相当熟悉RRDTool的用户，将立刻意识到：Cacti中的图形是紧密模仿RRDTool的图形的。一个很了不起的事是对于RRDTool，Cacti提供一个友好的接口，而不需要用户明白RRDTool是如何工作的。鉴于此，Cacti的每个图形都有某种设置并且至少有一个图形项与之相关联。图形设置定义全部属性，图形项目所定义的数据将在绘图时被呈现。}
Each graph and graph item has a set of parameters which control various aspects of the graph. Fortunately through the use of graph templates, it is not necessary to understand the function of each field to create graphs for your network. When you are ready to take on the task of creating your own graph templates, extensive field descriptions for both graphs and graph items are provided in that section of the manual.
{每个图形和图形项目有用于控制图形各种各样的面貌设置参数。有幸的是，通过使用图形模板，不必要明白每个字段的功能，就可为你的网络创建图形。当你要准备建立自己的图形模板时，在手册的部分章节中有对于图形和图形项目的大量字段描述。}
