[otrs] about stats menu

Hi all, In menu stats, with format graph, there have two axis (x and Y). The question : what is explanation of y axis? 1. what is explanation of y axis from new ticket (value of y axis = 0 2 4 6 8 10) ? 2. what is explanation of y axis from ticket overview (value of y axis = 0 1 2 3 4 5) ? 3. what is explanation of y axis from state action overview (value of y axis = 0 5 10 15 20 25) ? If I use format CVS, then system will open that format with Microsoft Excell program, and when I open that, appearance in excell program is in disarray. Why that can be happen, and what is solution? Thanks for your reply, but I am sorry before if I have wasted your time, thanks.
