The InteractiveImage in datashade seems like a huge win for looking at time series with millions of points. Hopefully I can move to this approach and away from my current dygraph usage.
I have two questions about using InteractiveImage with a time series using the techniques at the end of notebooks/tseries.ipynb:
When putting several series in the same interactive image, it’s helpful to have a mouse-over/hover to identify the series and point; and/or a legend (ideally like dygraph legends, which are sort of liked docked hovers in that they always show the points and identify the series). I see how to get hovers with non-interactive images from the notebooks/hover_layer.ipynb example; but it wasn’t clear to me how to get this working with InteractiveImage.
I like that the column layout can synchronize two or more bokeh time series (e.g. same time scale but different y axes), letting the user zoom with mousewheel on one and updating the others. Is it possible to put several InteractiveImages in a column layout and achieve a similar synchronization?
Thanks for putting the datashade pipeline together. It promises to be a very valuable tool.
