brainpy.analysis.PhasePlane2D.plot_nullcline has two branches

[Newtonpula]

In my single compartment HH-like model, the nullcline of the voltage variable has two branches. When I use brainpy.analysis.PhasePlane2D.plot_nullcline() to plot the nullcline, the endpoints of the two branches are connected. Is there any way to avoid this?

can you show the image?

what does the endpoints of the two branches are connected mean?

The middle part of the N-shape V nullcline should not exist, it just connects the endpoints of the left branch and the right branch of the V nullcline.

Attach is the same plot with fmt='o', but I want to use fmt='-'.

Maybe you need to plot by yourself. plot_nullcline(with_return=True) will return all points, and then you can draw what you want. Can this solve your question?

Yes, it solves my question. Thanks very much.
