update the variable resistance value during running simulation

[gsdfg]

Hello

how i can show the effect of changing the value of the variable resisttor at our circuit at the simulation graph without stop running and return it

i want to change the value during the simulation running and see the effect of this at the simulation

If you place a variable resistor (or potentiometer) in Multisim you have to ways to change its value during a simulation

• change the value using a pre-assigned keyboard key (set in the value tab of the property dialogue); key increases value, shift + key decreases value
• position your mouse cursor of the component and a slider will appear. Move the slide to change the components value (new v10 feature)

Not this i mean

i can change its value but the effect of changing not appear at the simulation graph during running the simulation , it is only appear when i stop simulation and restart it

i want to see the effect at time , see the changing value effect without stop the simulation

i hope you understand me now

i use multisim 10

I assume with "simulation graph" you refer to an oscilloscope, right?

If you haven't set any trigger options, you should be able to see all changes right on the scope.

Can you attach the circuit you have problems with to this post.

What he means is he wants to be able to see effect of the change in the potentiometer's resistance value IN a simulation graph. He does not want to take more than one simulation graph at each resistance value.

So for instance, I want a graph of the gain of a circuit with a potentiometer. The potentiometer can be from 5kOhms to 10kOhms. He wants the x value of the graph to be the resistance values of the potentiometer and the y value to be the gain.

How do you find this?
