Combining results transient analysis with changing parameter values

Schematic Simulation (Ngspice)
1

I’m running a transient analysis on a simple detector circuit for which the resistor takes 3 different
values.
I wonder whether it is possible to show the output voltage of the three runs together on one graph in KiCad?

I don’t think the internal KiCad Simulator can handle and plot “stepped” data yet. I think the best workaround for your project is to copy the circuit 3 times and make three different outX nodes you can probe at the same time. Otherwise, you can look up how to do .control statements in 16.14.4.2 of the ngspice manual, and push your simulation to external ngspice.

This was just a trivial example, it would not be very practical to make copies of the circuit for a problem where you have a few hundred values for a component. I also know how to do the simulation from the command line with ngspice but my question was especially motivated by the desire to do this from within KiCAD.
Maybe someone else here does know whether this is possible in KiCAD?
