Posted - 02/26/2025 : 04:34:44 AM Hi I'm using OriginPro 2018b version and I'm struggling how to add top x-axys which is connected to bottom x-axis without formula. I have a data set with over 7000 rows where the x-axis (bottom one) represent time. I want to add top x-axis which will show wavelength change at given times. Data I have for this are represented by 21 wavelenthgs at specific times. There is no relation so I could use formula. Example of what I need at the top axis (wavelength is top axis and time is bottom axis): # Wavelength[nm] Time[s] 250 3399.39 260 3410.87 270 3421.94 280 3433.1 290 3444.69 300 3455.48 310 3467.15 320 3477.56 330 3488.76 340 3499.34 350 3510.32 360 3520.56 370 3531.75 380 3542.25 390 3552.63 400 3562.98 410 3573.36 420 3583.76 430 3594.14 440 3604.59 450 3615.11
Can anyone help me out here, please? Thank you in advance for the help. |

 All deviations look insignificant (ok, in my humble opinion). |

Thanks, Snow |
