Description
Trying to figure out to what degree this is possible with datashader. Having not really used this library at this point, this question may be pretty naive. Thanks in advance for any advice.
Am interested in taking a stack of arrays (larger than memory) and navigating through them in a Jupyter notebook with a slider. Would be nice to see the intensity range in a colorbar as well. The arrays themselves are usually `float32` though sometimes might be different (e.g. `int16`). The values in the arrays are simply intensities. Would want to normalize the view based on the maximum and minimum values in the stack. Can pretty easily represent this stack of images using a Dask Array that either pulls from a computation or, if necessary, pulls from a large file on disk. Could also provide something that acts like a NumPy reading directly from disk.
To what extent is something like this possible? Are there any useful examples that might be relevant for this use case? What sort of issues might one encounter trying to handle this use case?
