Hi You can set up a transistor curve tracer type of circuit like this: <https://easyeda.com/file_view_NMOS-curve-tracer_20UcuM3Xf.htm> To find out more about probing currents and voltages, please see: <https://easyeda.com/Doc/Simulation-eBook/Introduction-to-using-a-simulator.htm#Probingsignals> Unfortunately at present, although it is possible to *run* stepped analyses of the sort you require, it is not possible to *display* them properly in EasyEDA. Please see this thread for more information: <https://easyeda.com/bbs_view_1806.htm> We are working to try to make this possible, so please bear with us. :)

If this feature is particularly important to you, please raise it as a feature request to bump it a little further up our To Do list. :)
