Hello, I want to plot data using a paleo time scale : time is decreasing from a positive value to zero (present day). The following script gives more details : ! Model Years are from 2000 to 7999, which correspond to nothing :-( ! I can define a time axis starting at 1, which it's less confusing LET nt = `t2m_yearmean,RETURN=lsize` DEFINE AXIS/T=1:`nt`:1/UNITS="Years" YearFromStart ! But the labelling I want is Year before present (present being 1850) LET/TITLE="Years BP" YearBP=6000-T[GT=YearFromStart]+1 ! I can not define the following axis because it's reversed !DEFINE AXIS/T/UNITS="Years"/NAME="YearBP" YearBP LET t2m = t2m_yearmean[GT=YearFromStart@ASN]-273.15 ! How can I use YearBP as an axis to have proper labelling ! of the time axis on the following plot ? SHADE t2m[Y=-2:2@AVE,L=1:5000@SBX:250] Any idea ?
