Is there and XDATA in GC manual that answers the following questions ?

- what data can you have
- from what source
- what are the requirements to have xdata in a workout
- how can you display those data in charts
- step by step example

- what data can you have

There are several with special treatment s.t. Weather, Hrv, Pool Swim lenghts plus Developer from Garmin Apps and User defined created in Editor.

- from what source

From several of the supported file formats on import and from manual input on Editor tab.

- what are the requirements to have xdata in a workout

If one of the supported XData series is present in the imported file the corresponding XData series will be created and you will see a corresponding tab in Editor, additionally you can create your own XData series in Editor.

- how can you display those data in charts

In Editor chart you can see XData in tabular format, In the Ride chart you can use XDATA() to plot it, for Summary and Metric Trends Charts you would need to define custom metric summarizing the XData you want to plot, both are documented in link provided in the previous response.

- step by step example

Search this forum and you will find examples.

That gives a cleared picture of what XDATA is and how you can use it.

I am interested to import Developer data from garmin apps and i managed to do it.
However i found some issues:

- the column headers/titles are not imported from the fit file. i have many columns of data without showing what each column is.

- i have figured out what each column is about and i created new empty columns (data series) with the appropriate title and copy paste the data.
All looked fine and i wanted to delete the duplicate data series. I deleted the column i didn't need but instead the editor deleted
the far right column,  not the one i wanted to delete.
Is this the way the editor works ?

Well, it seems that the lack of headers was an issue of the app. A updated version of it and the headers are there.

Something else i want to do but i don't see how.
I want to create a custom field under the details page, average the values of a XDATA series and feed that average value to the custom field.
Is there a way i can do that ?

Thanks

To average/summarize XDATA you need a Custom Metric, here you can find examples: https://groups.google.com/forum/#!topic/golden-cheetah-users/6uutChHZtVo, that metric will behave exactly the same as a builtin one, so you can use it in Summary, Intervals, Metric Trends and, Details if you want the ability to manually override the computed value.
