And I dont know what exactly you are asking for :)
Please explain further...
(we can see a line at 3.01 and at 2.5)

@Pl45m4
I'm sorry, As you can see , line 3.01 and line 3 are next o each other , I want line 3 to be place in the middle of line 3.01 and line 2.5 .
I would greatly appreciate it if you help me

What kind of axis should that represent?!
I'm currently not using QCustomPlot but you have to work on your y-axis for that...
I dont know if creating such an axis is possible since it's not linear anymore...
and I dont even ask why you want to do this.

The distance from 3 to 3.01 is +0.1 and to the lower line -0.5... How can this be in the middle?!

You can draw a line there any time, but not with a value of 3 on a linear scale...

QCustomPlot only provides two options:

Linear and Logarithmic scale.

Edit:

Are you trying to plot a sine wave by any chance?! And these are your two upper and lower bounds and you want the 0-base line in the middle between 3.01 and 2.5?
