print axis scale

[Christian H. <po...@we...>]

Hi,

I make gif-dataplots with gnuplot under linux. I use the autorange function. 
For further processing I need to know the scale of the generated y and y1 
axis. So I would like to have an output (stdout) like this:

Y1-Max: 55
Y1-Min: 45
Y2-Max:2.9
Y2-Min:1.2

Can you give me an hint were the axis is calculeted and were I can find 
these values.

Thanks
Christian
