[Qucs-help] Question about diagrams

[George K. <gko...@ho...>]

Dear Qucs Team,congratulations for the developement of this amazing piece o=
f software. The fact that such programs are under the GPL licence is very p=
romising...I have a question I'd like to ask. Could you please tell me if t=
here is a way to change the data item on the x-Axis in the diagrams? I am t=
rying to depict the i-v curve of a diode under a dc Voltage source when a r=
esistor is connected before the diode (in line). In other words, i want the=
 diode's voltage (not the source's voltage) to be in the x axis and the cur=
rent in the y-axis. I tried the PlotVs equation but i get a "wrong dependen=
cy" message in the table (the dependency remains on the source's voltage so=
 the x-axis remains as it is).An idea to solve the problem could be replaci=
ng the voltage source with a current source (so the current, which is the s=
ame everywhere in the circiut, is the independent data) and then measuring =
the diode's voltage, but with  the axes being reversed, but i don't know if=
 this is possible.Thank you in advance and congratulations,George Kourkafas=
Greece.
