Removing Redundant Sweep Variable in ViVa/Calculator

Hi,

A situation that I've come across from time to time when post-processing simulation data in Viva/Calculator is the existence of redundant sweep dimensions (not sure if that's the right term?). For example I'm using a parameter set to run a sweep over temperature (parameter "temp") together with a voltage (parameter "xvgp", in the actual hardware derived from a calibration method):

MyParamSet paramset {
    temp    xvgp
    -55       916.8530696902448m
    -20       959.7976945898896m
    -10       970.7410832539419m
    0           981.2754576448658m
    10         991.4617212964698m
    20        1.001347425921815
    30        1.010970233175010
    40        1.020360314587679
    50        1.029542060908037
    60        1.038535328826547
    90        1.064532656049035
    125      1.093268593744468
}

ViVa now also interprets "xvgp" as a sweep variable, even though the sweep of interest to me is only that over "temp", and "xvgp" is a redundant dimension:

This creates a lot of issues when post-processing the simulation data, for example data is plotted as individual points rather than a continuous line. In the past I worked around this by using the "average" Calculator function which removes the excess dimension.

I wonder if there's a more elegant and fundamental way of solving such a situation, for example with an existing Calculator or a specific SKILL function?

Thanks very much for your input.
