Thanks for your response.
It is mapped as Number Field (and I was aware of that).
So if it is mapped as a number field is not possible to apply a mathematical formula to convert it to some readable date format?
For e.g. it would help me if I can pick the first timestamp and deduct it from all following ones so that the chart starts with zero. That would be much more readable than the way it currently is (see screenshot)
It is after all possible to apply a mathematical formula on the y axis as shown here to convert nano sec to sec.
Thanks in advance.
