How could I draw a graph with a parameter like resistance on the x-axis?

[Eddie123]

I want to run an analysis that plots a voltage as a function of resistance. The parameter sweeps just make separate lines on the graph corresponding to the different resistances but they are still functions of time. Also If I could get gain as a function of resistance that would be great too(in ac).

For this case, you need to make use of the Export to Excel function (or Mathcad or LabVIEW). Export all the traces and you will have a spreasheet in excel that in the column header has the resistance, and then you will have two columns beneath it, one for time and one for voltage. In this way, you could then select one row, that is... one specific point in time, and graph Voltage as a function of resistance.

ok thanks. But now how about if i wanted to do a transient analysis in ac for a few cycles of the signal and have a resistor vary as a function of time?

Is this still not possible within Multisim v12.0?

Do we still have to export to an external graphing software to plot graphs with user specified x and y axes?

Thanks,

Hello,

You can try a paramater sweep. Under Simulate >> Analyses, select Parameter sweep analysis. You wont get  a resistance change based as a function of time but you will get an individual analysis on each parameter level(such as resistance). This hasn't changed from version 11.

Cheers,
