This seems like it should be really straight forward, but I can’t find any examples of it and my own code doesn’t work.
I’m trying to plot what is effectively a giant image (a spectrogram which is larger than what can be loaded into memory). I can bring it in as a dask array and create a DynamicMap of an Image, but when I go to rasterize it hangs. I’m assuming that this is because it’s trying to rasterize the entire dataset, which will take ages, even if it is able to do it without running out of memory. Ideally, I’d set an initial slice for it to plot and then let the user pan/zoom to other regions. I think I could do this with kdims, but I don’t know how to link kdims to the panning/zooming in bokeh plots.
Are there any examples of plotting datasets which don’t fit in memory? Is there a way to set the initial slice which is plotted?
