Hi,
I would like to plot a graph with two x axis, with the second one linked to the first by a non linear formulae like x2=a*x1^2. But I would like to put the ticks of this second axis where I want and not at the same positions than the x1 ticks.
Can someone help me ?
Thank you in advance !!

Thank you James, it's working now, I think I reversed inverse and direct formula because it is not intuitive for me that the formula to go from bottom to top axis is the inverse formula...
Thank you again for your help |

I think the problem comes from there is a factor 10^30 in my inverse formula and Origin cannot handle it ... |

That means if the x scale of bottom axis is from x1 to x2. Then the upper axis scale should be set to f(x1) to f(x2) where f(x) = -0,8887+8,03888E-4*x+7,21815E-7*x^2

Hi,
Make sure the upper x axis scale range ought to accommodate the lower x axis scale.

I'm not sure to understand what it means. Is it related with the error message "From value exeeds the range of inverse formula" ?
Actually, my formula is a little more complicated : -0,8887+8,03888E-4*x+7,21815E-7*x^2

Hi,
Please first add upper x axis, then make the settings as shown in the figure. Make sure the upper x axis scale range ought to accommodate the lower x axis scale.
