Fourier Transformation on a TGraphErrors

Hi,

I’m searching for an easy way to perform a Fourier Transformation on an TGraphErrors. It looks like fft is only implemented for histos. Or did I just not find the function?

Cheers

yes currently we support only fft with histograms. You have 2 options;
-fill a histogram and call hist->FFT
-or use the code of TH1::FFT and replace the calls to fft->SetPoint by the graph data
