I chose the node to be plotted and saved, but still I can't get the current waveform.

Why??

Because you can plot current only trough terminals of components.
The node current is always equal to 0 according to Kirghoff law.

Can the terminal current of a capacitor to be plotted? I chose the terminal of a capacitor but nothing appeared.

try to put a zero resistance on the wire and measure the current passing through it ,, or try to put an iprobe
don't forget to save te currents

Instead of zero resistance put VDC=0.
Because if you use high-value resistors in your design and put almost-zero resistor the simulator will have problems with convergence.

Can the terminal current of a capacitor to be plotted?

Sure! But by default currents aren't saved. You should select this option in "Outputs -> To Be Saved" or "Outputs -> Save All" forms.
