Hello everyone !
I've a big issue with my origin (Origin 2018b, 64-bit, windows 10).
I want to do a graph with a X axis with temperature (°c) and one with the linearisation of the température (1000/T(°k) ).
For that, I add a second layer for the second x axis but the scale is never good whatever I tried (by formula, link to the first X axis or by manually putting the beginning and the end of the second x axis).
In the "plot detail -> TopX -> Link Axes scale -> X axis link -> custom " i've put :
X1 = 1000/(X1+273.15)
X2 = 1000/(X2+273.15)
I got approximatively a good scale, but the number are not well aligned (e.g. : 60°c must correspond to 3 but here is around 3.07)
Thanks by advance, this stuck me from few days ! :)

Hi,
I am not sure how you want the axes ticks to be aligned. According to your formula:
X1 = 1000/(X1+273.15)
60°c corresponds to around 3.002. Why you want it aligns to 3?
Thanks,
Amanda

Hi,
I don't want it to be really aligned, but here 60°c should be almost at the same place than 3, when is around 3.07 (the scale is 10->110°c so ~3.53-> 2.61.
Meaning that a difference of 0.7 is quite big in this scale :)
I don't understand from where this problem can be...
here the origin file with this graph : https://transvol.sgsi.ucl.ac.be/download.php?id=2931cdad6638ec4b |

The transferred scale is not linear, so you cannot do that in PlotDetails and still keep them aligned since both side would still be linear by them self.
You can try using custom option in Axis Dialiog, Scale tab. |
