Hi,

I need to create a waterfall plot where data is represented incrementally by horizontal 'bars' moving down the plot and the intensity represented by varying colors across each horizontal bar. It looks like the sprectrogram would be perfect for this application, and I am able to create and run the example without any problems, but I do not understand how I would modify it to get the horizontal bars moving down the plot over time that I need to show. I am totally new to using raster plots and do not have a good enough understanding of how the data is handled to get my data displaying properly. If anybody has created an app with similiar requirements using the spectrogram or any other widget I would appreciate any advice and/or a piece of sample code to get me started. Thank you in advance...
