Dear all,I am trying to plot the current density using the command:kwant.plotter.current(syst, current, cmap = 'spectral_r',linecolor='black', density = 0.5, colorbar = True). However, when the figure is plotted, the colorbar doesn't appear. I know that this is a simple matter, but can someone indicate to me what am I doing wrong?Best Regards,Luan
