Weird voltage on resitor with Zener diode

I have very simple setup: - 1k resistor - zener diode - 9V power

Wanted to run DC sweep to observe how voltage and current will behave when I increase voltage from 0-9V. Current behaves properly as Zener diode is blocking current until it reaches Vz - hence 0-5V - we see zero and from 5-9V current is growing linearly according to Ohm law. Voltage is weird....as it grows from zero on resitor. How? If current is zero :)
