I’m using the graphael to create line plots. I want to create a zoom, that is, I have the array and I want the values between -20 and 30. Since my values are between 20 and 25 on the y axis, I want to add between -20 and 30 and recalculate to be well positioned between the new values. I don’t know if it has to do with the Gutter used in the library.

I was able to get to what I wanted, I just have a small problem with the x axis. example: http://jsfiddle.net/vpGyL/1431/
