I have a number of curves of drug concentration vs. time. The time scale, on the horizontal (x) axis, is normal, while the concentration scale is logarithmic (the equidistant notches say 1000 ng/mL, then 10 000 ng/mL, and then 100 000 ng/mL).
In Russian, the curves are called "logarithmicized curves" (логарифмированные графики индивидуальных концентраций препарата) in my document because of this. What do I call them in English?
I looked up logarithmic curve - but it's a curve described by a logarithmic equation, while in my document the curves do not look like that at all - they go in zigzags, up and down, not in nice rounded lines in one direction, like logarithmic curves.
