Can you add a battery?

Unfortunately it is not yet possible in EasyEDA to run multiple (stepped) simulations to produce a set of plots all on the same axes (like on a transistor curve tracer). However, it is possible to set up a simulation to plot the DC output of a circuit vs. the potentiometer slider position. If this is what you require then please post back and I will try to set up an example for you. In the meanwhile please have a look at: https://easyeda.com/editor#id=mC82kCTN5 You may also find the EasyEDA Simulation eBook helpful in discovering how to set up such swept plots and using parameters and expressions. The eBook will also help you to understand how to set up the basic simulation including ground and power supply. You can find the eBook under "Resources". :)

Thanks, In this particular case I needed the pot. but will review docs as suggested for sweeps. Thanks
