Good afternoon,
I'm looking to create a HTML document with a {leaflet} map in it that helps track the development of a pollution episode. I'd like to create a user interface in which a user could drag a bar, similar to crosstalk::filter_slider(), which would update the corresponding {leaflet} map to show data from that date.
I don't want to do this in {shiny} to make this more shareable.
What I've tried:
-
{crosstalk}- it only seems to have a two-value range slider, which isn't any good for me (I want to show one day's pollutant concentrations at a time, not two or more). -
{leaftime}- it seems to have an upper limit on the amount of data it'll use before it stops working. -
{leaflet.extras2}- it won't show every marker initially, it seems more set up to show a single marker moving over time rather than a lot of markers changing colour.
I think the solutions I have in my head are either:
-
A single value equivalent of
filter_slider()where you select one date, or -
The ability to lock the width of
filter_slider()to one 24 hour period so that users can still drag the range about, but it'll only ever be 1 day in width.
I'd post to the {crosstalk} repo but it doesn't look like its been updated in 2 years so I'm not confident its being developed that actively.
Cheers,
Jack
