I was wondering if it was possible to issue an htmx get request to an html block containing a chartJS canvas.
I have a piece of html containing a canvas generated with Chart JS that get called with an HTMX get request but I am unable to generate the chart once the get request is complete.
I have put all the dependencies of chart js in the main html but It is not working.
I also tried to put all the dependencies in the html fragment that gets called by the HTMX GET request but it is not working either.
Is it possible?
Here is what I have so far:

What am I doing wrong? The intent is to have a few (say 6) leafletjs panes, each containing many markers and polylines, so the panes can be hidden independently. Here is a simplified program showing just two lines and markers in jsfiddle. The problem is, the polylines all get grouped in the same SVG and all get hidden together. Each pane in the example should show one polyline and one marker.
I don't want to remove the polylines from the map to hide them, then recreating them would not perform well.
If needed, the polylines could be drawn using D3 on top of the leaflet map but I was hoping it could all be done in leaflet.
Thanks!

L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {

}).addTo(map);
var pane1 = map.createPane('pane1');
var pane2 = map.createPane('pane2');
function hide(pane) {
pane.style.display = 'none';
}
function show(pane) {
pane.style.display = '';

Is it possible to create pushpins from addresses instead of lat/long data?
I guess the pushpin constructor accepts only locations which are a lat/long representation of the location.
new Microsoft.Maps.Pushpin(value)
Is there any solution for creating pushpins from addresses.
Here is a sample code showing you how to find a location by address:
<!DOCTYPE html>
<html>
<head>
<title>searchbyaddressHTML</title>
<meta http-equiv='Content-Type' content='text/html; charset=utf-8'/>
<style type='text/css'>body{margin:0;padding:0;overflow:hidden;font-family:'Segoe UI',Helvetica,Arial,Sans-Serif}</style>
</head>
<body>
<div id='printoutPanel'></div>
<div id='myMap' style='width: 100vw; height: 100vh;'></div>
<script type='text/javascript'>
function loadMapScenario() {
var map = new Microsoft.Maps.Map(document.getElementById('myMap'), {
/* No need to set credentials if already passed in URL */
center: new Microsoft.Maps.Location(47.624527, -122.355255),
zoom: 8 });
Microsoft.Maps.loadModule('Microsoft.Maps.Search', function () {
var searchManager = new Microsoft.Maps.Search.SearchManager(map);
var requestOptions = {
bounds: map.getBounds(),
where: 'Washington, DC',
callback: function (answer, userData) {
map.setView({ bounds: answer.results[0].bestView });
map.entities.push(new Microsoft.Maps.Pushpin(answer.results[0].location));
}
};
searchManager.geocode(requestOptions);
});
}
</script>

when you mouse over a cluster, Leaflet.markercluster should show the bounds of its markers. this is the (simplified) code I am using:
map = new L.Map('map');
L.tileLayer(
'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
maxZoom: 13,
attribution: 'Map data © OpenStreetMap contributors'
}
).addTo(map);
map.setView([51.505, -0.09], 11);
let deflate_features = L.deflate({
minSize: 40,
markerCluster: true
});
deflate_features.addTo(map);
var polygon = L.polygon([
[51.509, -0.08],
[51.503, -0.06],
[51.51, -0.047]
]);
deflate_features.addLayer(polygon);
var polyline = L.polyline([
[51.52, -0.05],
[51.53, -0.10],
], {
color: 'red'
});
deflate_features.addLayer(polyline);
#map {position: absolute; top: 0; bottom: 0; left: 0; right: 0;}

why does the cluster coverage on hover not show?
coverage is not shown if there are only 2 objects... :|
adding a third object, e.g.:
var polyline2 = L.polyline([
[51.535, -0.1],
[51.525, -0.05],
], {
color: 'green'
});
deflate_features.addLayer(polyline2);
enables cluster coverage:

I am looking add custom Html elements such as textbox, textarea to bing map pushpin therefore it can be editable when it placed.
problem is can be place push pin with textbox or textarea but it cannot be editable.
This is a limitation of the default infobox class. You can work around this by using the custom infobox module found here: https://bingmapsv7modules.codeplex.com/wikipage?title=Custom%20Infobox%20Control
