change x-y graph step by step

[Mido]

Sir

i am simulating a lab expirement (resonance expirment),i have made the curves for the test but it is required to change the curves when changing the frequency (from 300 to 3000 Hz for the required load)... as the load changes till reaching minimum impedance while maximum current(resonance time),,i was unable to let the load & current curves changes with each change in frequency,,plz try to modify my VI ,,deeply  thnx for your efforts ,,
best regards...

Where are you changing your frequency?  All values on your front panel (inductance, capacitance, voltmeter, resistance)  are actually indicators which just display the values that are hard coded in your block diagram as constants.
