Visualisation is an important tool for many steps of a research project. In this paper, we present several displays of audio data based on stacked graphs. Thanks to a careful use of the layering the proposed displays concisely convey a large amount of information. Many flavours are presented, each useful for a specific type of data, from spectral and chromatic data to multi-source and multi channel data. We shall demonstrate that such displays for the case of spectral and chromatic data offer a different compromise than the traditional spectrogram and chroma gram, emphasizing timing information over frequency.
