!!! Error of set key graph in gnuplot ver 4.6.x

After periodic maintenance on 2013 Sep. 2, gnuplot on data analysis servers and terminal workstations is updated from version 4.2.6 to 4.6.3.

Since gnuplot changes command format of "set key graph" from version 4.4, loading of a macro file made by previous version may show following error message:

 gnuplot> load "mygraph.set"
 gnuplot> set key graph 0.7,0.95
        "mygraph.set", line 15: unknown key option

In this case, you can load the macro file by editing the file like this:
  set key graph .....
  -->  set key at graph .....

Similarly, when you want to execute "set key graph ....." on command-line, you need to input "set key at graph .....".
