Signal from Graph to FFT

[needtolearnfast]

I have a singal which has been stored to a binary file. I want to take it out and run a FFT on it and see all the peaks on one graph. Is this possible, I have tried and all i get out is garbage, but maybe I'm doing somethign wrong(most probably). Thanks for the help.

If the binary have not been generated by Labview, your problem might have to do with the reversed byte order used in LV (BIG ENDIAN vs. LITTLE ENDIAN). you can search for 'ENDIAN' in this forum to find tips.

Or use the following code snippet:
