Is it possible to reverse axis order in LabPlot?

Hi, I am trying to plot FTIR data. The x-values in my spreadsheet are sorted in descending order, but my plot has x-axis has values that ascend from left to right. Is there a way to easily reverse this? Thank you.

Hi @Lsotsky1,

This feature hasn’t been implemented yet. It’s on our TODO list: Support "reverse" option for axes (#1008) · Issues · Education / LabPlot · GitLab .

However, it’s possible to manually switch the start and end values for the ranges. Please, see the attached image.

Hi, thank you so much for your message. I look forward to seeing the update. I wasn’t sure this was possible because after switching the start and end values, the labels on the tick marks would disappear. After seeing your message, I realized I had to also uncheck Auto for the ticks as well. Thanks again.
