How plot 2 lists in PlotWIdget within flowchat after a CtrlNode?

[João Felipe Alves da Cruz]

Hi,

I am trying plot two nest list in PlotWidget connected to a control node with data in and out. The Node has a function (fourier transform) that generates these two lists.I need see both graphs same PlotWidget.

Any idea?

Thanks

João Felipe.

I need that two plots occupy the same scene in same time with different colors.

What is the problem with using addItem and changing the pen color for the different plots?

I think that can't use addItem (or don't know how use) and change pen color, because have to modify inside node (PlotWidget) or function PlotWidget.
