function call mistake while fft calculation

Hello, I am calculating harmonics, THD etc. for plotted signals. I defined a button which calls a function to calculate some parameters. This function callss another one to calcualte fft and related things.

I defiend my button like this: pb1 = uicontrol('Style','pushbutton','String','plot FFT','Callback','plot_fft(x,ASM_6ph_voltages.signals.values(:,7),max_step,f_fundamental)'); Here x is defined as time vector.

Then in plot_fft function it calculates some parameters and calls the fft_synth function.

If I push the button on the graph it doesn't work. But when I start the plot_fft function in command window, it works.

What may be the reason? Thank you very much in advance.
