2 axis of different type
type: item
description: Dear all, I'm trying to plot the concentration of a atmospheric molecule (xaxis) vs the pressure (yaxis). The pressure axis should be in log. scale. This is well done by the command: PLOT,concentration,pressure,/ylog,yrange=[MAX(pressure),MIN( pressure)] $ ,ystyle=9,position=[0.1,0.1,0.9,0.9] After that, I want add an altitude (in km) axis on the right, in LINEAR scale. It should be done by: AXIS,yaxis=1,ylog=0,yrange=[z1,z2],ystyle=1 where z1 (respec. z2) is the altitude corresponding to MAX(pressure) (respec. MIN(pressure). The result is that the altitude axis is in log. scale. If somone could help me, Thank you, Cheers, Quentin.
