Multi Dimensional Plot using parametric analysis

Hello,

I am using parametric analysis of noise simulation with three variables (L, Vdd, Vg) in the simple circuit shown below (L=60nm to 3um, 20pts), (Vdd=0 to 1, 10pts), (Vg=0 to 1, 51pts).

The parametric analysis looped on all variables correctly as shown below, but when I try to plot the thermal noise, the output family of curves are shown for the first value of L=60nm only with all combinations of Vdd and Vg.

Is there any way I can plot all curves with all variations (L, Vdd, & Vg) in Cadence Virtuoso ADE L? 

I am using the following versions:

MMSIM Version: 13.1.1.660.isr18

Virtuoso Version: IC6.1.8-64b.500.1

irun Version:14.10-s039

Spectre Version: 18.1.0.421.isr9

Many thanks in advance!
