Independent data ranges (independent axes) are something that is currently missing in Labplot. Due to this, a number of plots cannot be plotted with Labplot. In the attached pdf is a complete proposal on how to implement this feature in the software, together with other suggestions related to this implementation to make the life of the user easier. This task is also tied to bug number [[ https://bugs.kde.org/show_bug.cgi?id=403304{F8251301} | 403304 ]], to which I have attached a Scidavis project file to give you a working example to work with while implementing these features.
