Feature request: converting HoloMap to DynamicMap

[basnijholt]

I use DynamicMaps to show a lot of data, sometimes ~1000 plots with 7 variables.

I love how easy it is to compose a HoloMap, but it's not useful because rendering it takes a very very long time.

The DynamicMap offers a solution to this problem, but it's more cumbersome to write.

Putting a 1000 plots in a HoloMap is still quite cheap (just a couple of seconds), therefore I would like if I could just apply hv.DynamicMap on a hv.HoloMap to get the ease of use of a HoloMap, but at the speed of a DynamicMap.

You should just be able to create a DynamicMap from a HoloMap using:

hv.core.operation.DynamicFunction(hmap)

However is there any reason not to simply use:

%output widgets='live'

Edit: Thinking about it, live can be slow because creating a plot from a HoloMap can take a little while to compute all the ranges and other things.

This is very slow and takes a few minutes before I see anything.

That is great! I'll try it out 😄

hv.core.operation.DynamicFunction(hmap)

Has a few problems still, it doesn't set the set of the dimensions:

Thanks for the bug report, should be an easy fix.

This function will be moved and renamed to hv.util.Dynamic in the next release.

hv.util.Dynamic now exists and the bugs described here have been resolved. I will close, please reopen if you encounter any issues.
