Hi,

Here is my result so far for you to understand.

I have to display the lines of several units.

The problem (visible in the screenshot) is some units are too small square in the graph relative to the other.

What I want is to know how I can force multiple scales on my y-axis.

For example 0-100 on a tier of the axis, from 100 to 1000 for another tier and finally which is higher than 1000 in the last tier

thank you
