I could see that, Y2 values were imputed or calculated in the above code - y2 = (0.2 / 50)*y; However in reality, we have two separate variables Y1 & Y2 has the data which is independent in nature. In such a scenario, I am still not able to fix the issue. ... View more

Basically, I need to present two different parameters data on Y1 & y2 respectively with a common X axis (an individual concentration plot). Y1 values has a range from 0.1 to 60000 & Y2 has 0.01 to 600. we need to present this in semi-log view & has a note for programmer from stats - "Scale axis such that 0.2 on Y2 axis corresponds to 50 on Y1-axis". ...

Thank you so much for your guidance.   Could you also suggest me on the following..   Once we have the desired tick values, I want to align Y1 values with Y2 axis values with a formula of 0.2 on Y2 corresponds to 50 on Y1. Is there a way to standardize/align the Y1 & Y2 axis scales in log view? I tried in linear view by giving equal number of tick values on Y1 & Y2 axis. This gave me the tick values placement on corresponding values i.e 50 of Y1 to 0.2 on Y2.    Best Regards,  ... View more
