How to get the X and Y axis limits of the current waveform window

I would like to use awvPlaceWindowLabel() to place a label in the waveform window at a calculated position, in data coordinates, relative to a number of waveforms.

The coordinates supplied to awvPlaceWindowLabel() must be in absolute coordinates ( 0 to 1 ) while I know the position in data coordinates. I could easily convert from data to absolute coordinates if I could determine the X and Y axis limits. I cannot find a means of querying the current waveform window and returning the X and Y limits.

As an alternate approach, I tried using awsPlaceWaveformLabel(), which does use data coordinates, but the label is placed as a marker which I don't want since it has "text bubble" drawn around it.

I'm aware of  the functions awvSetXLimit and awvSetYLimit for setting the axis limits, but I cannot find anything equivalent to a "Get" function such as awvGetYLimits. Any suggestions of how this may be done would be appreciated.

If it matters, the limits are to be determined for a waveform window plotting an eye diagram. My Cadence version is: IC6.1.7-64b.500.20.

Thanks.
