Has the NORD field of that waveform record been set correctly?  What happens if you do caget on it?

Subject: CSS xy graph question

Hi,

I have a question regarding the XY graph widget in CS Studio.
I want to define the x axis labels based on an array read from my areadetector
driver. The PV is of type waveform with 4000 elements of type double and
contains one value per bin.  If I put this record as "X PV", the widget shows
an error and the message that the value of this PV is nil.

The reason for this is, that the driver is universal for a class of
spectrometers where every pixel in the sensor stands for a certain wavelength.
Different devices have different ranges of wavelength they cover.
Of course I could hard code the range, but then one needs to generate a
separate OPI file for each type of device.

What is the correct type for the PV that defines the x axis?

Regards,

Jörn Dreyer
