Should be very simple. But I can not find this in documentation. The origin programming is often extremely frustrating.

So - is it possible to access x-data of a range or dataset in Labtalk, Origin C or whatever? How?

There is GetData in Range object, which seem to be able to do this, but the call is very complicated - one has to specify lots of parameters, including mother's maiden name (well, almost).

Hi,

Do you mean you have a graph active and want to find the x-data associated with one of the data plots in the graph layer?

If yes, for Origin C, see GetDataRange under DataPlot class:
http://www.originlab.com/doc/OriginC/ref/DataPlot-GetDataRange

For Labtalk, an example:

// Declare range variable for x data of the 2nd plot in the active layer
range -wx rwx=2;

which is documented here:
http://www.originlab.com/doc/LabTalk/guide/Range-Notation#Graph_DataRange.2C_Graph_Data
