These functions are foreseen to pass your data to this class: void SetImage(TArrayD & imageData, UInt_t width, TImagePalette * palette = NULL); void SetImage(Double_t * imageData, UInt_t width, UInt_t height, TImagePalette * palette = NULL); You see, your data should be either an array of Double_t or a TArrayD. You also can define a palette for your color representation of your data. I hope to have a first version next month. Cheers Reiner.
