although an xy-plot can have multiple x- and y-axis I can't find a way how to map certain data to either of those axis. It could also be my ignorance of course thx Michi

The additional axes in LabPlot have a different meaning, they allow the user to "format" certain data range differently (use a different number of ticks, different scaling and labels, etc.) for certain parts of the visible data regions. New axes don't change the data ranges. Those are determined by the data range properties as defined in the properties dock widget of the plot. We need to re-think our current approach for how we handle axes and to also implement the mapping of data to new axes, as you described. This is what many other users have asked for already, too.

As an addition to this, it would be really helpful to scale the data against the given axis. I would like to be able to have one set of data plotted linearly and the other logarithmic. Right now all log(y) seems to do is change the tic spacing.

LabPlot (master) now supports multiple plot ranges. More details in https://phabricator.kde.org/T13016 Find screenshots and example projects attached.
