I need to represent four different responses (Y) in a combined way.
Y1 ranged from 170 to 300 nm,
Y2 ranged from 270 to 1200 nm,
Y3 ranged from 400 to 2500 nm,
Y4 ranged from 0.9 to 4.0.
When combined, the Y-axis ranged from 0 to 80. Is that correct?
What is the explanation for this change? Is there any way to manipulate the Y-axis values?
