Is there any software to plot voltages & current in polar and complex notation?. Could it be posible with LTSPICE?, I want to plot everything shematics, more simulation in the same software avoiding the use of spreadshets.
thanks again.

 

LTSpice cannot do polar plots.

The data can be exported to GNUPlot or a spreadsheet for plotting.

Otherwise, Berkely Spice is capable.

Orcad Pspice is capable, though it is mentioned "Through simulink with MATLAB", which is a bit uncertain. It is a limited demo anyway, vs. free Berkely Spice.
