How to control x-axis in plotting 2-dimentional sweep results (Vin sweep and PVT sweep)

How can I accurately control the cadence viva output behavior? The 2-dimentional results give the wrong x-axis for plotting. I want to use Vin sweep as the x-axis but the viva automatically plot based on temperature sweep in PVT as x-axis.

I use ade-xl to run a transient simulation with Vinput spwet from 10mV to 2V with step of 100mV. I can use "plot all" to obtain the waveform for circuit gain (y-axis) across the Vinput sweep (x-axis) and figure out the 1dB compression point by visual inspection. Now I apply the calculator function to calculate the 1dB compression point. Though the expression should only report circuit gain for one Vinput amplitute but it automatically report me the whole curve value and accordingly, I can apply the calcualtor function to this expression to calculate my 1dB compression pont.

However, when I run the above test across PVT, I find The "plot all" results is different to curve as above, instead, the viva will plot each curve across the temperature (x-axis) instead of Vinput as x-axis. How can I accurately control the ade-xl viva to plot the results with Vinput as the x-axis and each curve represents different PVT conditions?
