In bottom x axis I have (10^6/T^2) data in linear scale. I want to have a top x axis where it will show only T values but in reciprocal scale.
I have added a 2nd x axis as 2nd layer. Selected layer properties of TOP X and from 'Link axes scale' tab chose X axis link to custom and wrote: X1 = sqrt(10^6/X1) X2 = sqrt(10^6/X2) But the top x axis is not properly linked to bottom x axis. Top X axis is showing different values than T i.e sqrt(10^6/bottom X)
