• Fifst,you need your game console opened
  (Options->Keyboard/Mouse->Allow developer console->Enabled)
  首先,你需要打开游戏的控制台（设置选项->键鼠控制->允许开发者控制台->开启）
  

• Second,press "~" and type some commands below:
  其次,按下波浪键并输入以下几个指令并回车:
  

  net_graph 4

  ->ENTER
  

  net_graphpos 1

  ->ENTER(1 or 2 or 3 your choice,1 is right,3 is left,2 is middle)
  (123自己选,1就是右边,3就是左边,2是中间)
  

  net_graphheight X

  ->ENTER(X is your game Vertical Resolution minus 29pixels)
  (X就是你游戏的垂直分辨率减去29)

• Now,load a map and check netgraph is working or not.
  现在,建个图并查看下netgraph是否显示正常.

• At last,enjoy!
  最后一步,开爽吧！

• net_graphshowinterp 0
  or you will see two graph lines at screen bottom
  另外输入net_graphshowinterp 0
  否则你在屏幕下方会多看见两条线
  
  
• And,if you don't want to watch sv&var,just type "net_graph 3" in console
  还有，如果你不想看服务器刷新率和var值就在控制台输入net_graph 3
  
  
• Don't mind that green line at screen bottom,you cannot disable it,when net_graph is 4.
  不要在意那条底部绿线，因为net_graph 4的时候无法去除.

• Not everyone like netgraph always being there.So we need cvar ALIAS to make this work.
  不是所有人都喜欢时时刻刻看网图，所以我们需要alias指令来实现。

bind "tab" "+scorenet"
alias "+netgraph" "net_graph 4"
alias "-netgraph" "net_graph 0"
alias "+scorenet" "+showscores; +netgraph"
alias "-scorenet" "-showscores; -netgraph"

• This means netgraph would come out only when you hold your tab button down.That is convenient,isn't it?
  这就意味着你按下tab键的时候网图会显示出来，这很方便不是么？
  
  
• You can easily copy these in your game console or autoexec.cfg file.
  你可以轻易的复制这些指令到控制台或者autoexec.cfg文件内。

• Do not use net_graphpos 3 ,otherwise your scoreboard and netgraph will conflict each other.
  不要用net_graphpos 3，否则你的记分板会和网图冲突(一个压一个难受)
  
  
• And you can change the number of net_graph 4to 1/2/3 any you want.
  你还可以把net_graph 4中的4改成任意的1或2或3

• Just type it in your console or rescript previous content in autoexec.cfg file with
  只要在控制台输入以下指令，或者用它在autoexec.cfg里覆盖上面的那些指令

bind "tab" "+showscores"
