Dear All

[1] I am looking for graphing templates suitable for formal publications. I appreciate if you could share such templates if available.

[2] Also, I want to add a vertical line to my X-Y scattered chart to separate points say greater than x=10. I can add the line in Excel but I have difficulty setting its y value to match the max value of the x-axis automatically. I appreciate your help on this too. Also, is it possible to automatically add two perpendicular arrows to the bottom and top ends of the line, say pointing to the right? It is possible to do it manually by drawing it but I have to generate many graphs and I would prefer to be done automatically.

Thanks in advance
Simon
