## How to use
1. **include CSS & JavaScript**
```html
<head>
...
<style> html, body, #map, #elevation-div { height: 100%; width: 100%; padding: 0; margin: 0; } #map { height: 75%; } #elevation-div { height: 25%; font: 12px/1.5 "Helvetica Neue", Arial, Helvetica, sans-serif; } </style>
<!-- leaflet-ui -->
<script src="https://unpkg.com/leaflet@1.7.1/dist/leaflet.js"></script>
<script src="https://unpkg.com/leaflet-ui@0.6.0/dist/leaflet-ui.js"></script>
<!-- leaflet-elevation -->
<link rel="stylesheet" href="https://unpkg.com/@raruto/leaflet-elevation/dist/leaflet-elevation.css" />
<script src="https://unpkg.com/@raruto/leaflet-elevation/dist/leaflet-elevation.js"></script>
...
</head>
```
2. **choose the div container used for the slippy map**
```html
<body>
...
<div id="map"></div>
...
</body>
```
3. **create your first simple “leaflet-elevation” slippy map**
```html
<script>
// Full list options at "leaflet-elevation.js"
var elevation_options = {
// Default chart colors: theme lime-theme, magenta-theme, ...
theme: "lightblue-theme",
// Chart container outside/inside map container
detached: true,
// if (detached), the elevation chart container
elevationDiv: "#elevation-div",
// if (!detached) autohide chart profile on chart mouseleave
autohide: false,
// if (!detached) initial state of chart profile control
collapsed: false,
// if (!detached) control position on one of map corners
position: "topright",
// Toggle close icon visibility
closeBtn: true,
// Autoupdate map center on chart mouseover.
followMarker: true,
// Autoupdate map bounds on chart update.
autofitBounds: true,
// Chart distance/elevation units.
imperial: false,
// [Lat, Long] vs [Long, Lat] points. (leaflet default: [Lat, Long])
reverseCoords: false,
// Acceleration chart profile: true || "summary" || "disabled" || false
acceleration: false,
// Slope chart profile: true || "summary" || "disabled" || false
slope: false,
// Speed chart profile: true || "summary" || "disabled" || false
speed: false,
// Altitude chart profile: true || "summary" || "disabled" || false
altitude: true,
// Display time info: true || "summary" || false
time: true,
// Display distance info: true || "summary" || false
distance: true,
// Summary track info style: "inline" || "multiline" || false
summary: 'multiline',
// Download link: "link" || false || "modal"
downloadLink: 'link',
// Toggle chart ruler filter
ruler: true,
// Toggle chart legend filter
legend: true,
// Toggle "leaflet-almostover" integration
almostOver: true,
// Toggle "leaflet-distance-markers" integration
distanceMarkers: false,
// Toggle "leaflet-edgescale" integration
edgeScale: false,
// Toggle "leaflet-hotline" integration
hotline: true,
// Display track datetimes: true || false
timestamps: false,
// Display track waypoints: true || "markers" || "dots" || false
waypoints: true,
// Toggle custom waypoint icons: true || { associative array of <sym> tags } || false
wptIcons: {
'': L.divIcon({
className: 'elevation-waypoint-marker',
html: '<i class="elevation-waypoint-icon"></i>',
iconSize: [30, 30],
iconAnchor: [8, 30],
}),
},
// Toggle waypoint labels: true || "markers" || "dots" || false
wptLabels: true,
// Render chart profiles as Canvas or SVG Paths
preferCanvas: true,
};
// Instantiate map (leaflet-ui).
var map = L.map('map', { mapTypeId: 'terrain', center: [41.4583, 12.7059], zoom: 5 });
// Instantiate elevation control.
var controlElevation = L.control.elevation(elevation_options).addTo(map);
// Load track from url (allowed data types: "*.geojson", "*.gpx", "*.tcx")
controlElevation.load("https://raruto.github.io/leaflet-elevation/examples/via-emilia.gpx");
</script>
```
### Build Guide
Within your local development environment:
```shell
git clone git@github.com:Raruto/leaflet-elevation.git
cd ./leaflet-elevation
npm i # install dependencies
npm run dev # start dev server at: http://localhost:8080
npm run build # generate "dist" files (once)
npm run test # test all "*.spec.js" files (once)
```
After that you can start developing inside the `src` and `test` folders (eg. open "http://localhost:8080/test" in your browser to preview changes). Check also [CONTRIBUTING.md](.github/CONTRIBUTING.md) file for some information about it.
### FAQ
<details>
<summary>1. How can I change the color of the elevation plot?</summary><br>
There are multiple options to achieve this:
* You could either use some default presets (see: theme: "lightblue-theme" option in readme file and the following file `leaflet-elevation.css` for some other default "*-theme" names).
* check out [this example](https://raruto.github.io/leaflet-elevation/examples/leaflet-elevation_custom-theme.html)
* Or add the following lines for custom colors.
```css
.elevation-control .area {
fill: red;
}
.elevation-control .background {
background-color: white;
```

<details>
<summary>2. How to enable/disable the leaflet user interface customizations?</summary><br>
These customizations are actually part of the [leaflet-ui](https://github.com/Raruto/leaflet-ui) and can be toggled on/off using e.g. the following options:
```js
var map = L.map('map', {
center: [41.4583, 12.7059], // needs value to initialize
zoom: 5, // needs value to initialize
mapTypeId: 'topo',
mapTypeIds: ['osm', 'terrain', 'satellite', 'topo'],
gestureHandling: false, // zoom with Cmd + Scroll
zoomControl: true, // plus minus buttons
pegmanControl: false,
locateControl: false,
fullscreenControl: true,
layersControl: true,
minimapControl: false,
editInOSMControl: false,
loadingControl: false,
searchControl: false,
disableDefaultUI: false,
printControl: false,
});
```
</details>
<details> <summary>3. How can I import this library as ES module?</summary>
Usually, when working with a js bundler like [Vite](https://vitest.dev/) or [Webpack](https://webpack.js.org/), you need to provide to this library the full path to some dynamically imported files from the [`srcFolder`](./src/):
```js
import './your-custom-style.css';
import 'leaflet/dist/leaflet.css';
import L from 'leaflet';
import '@raruto/leaflet-elevation/src/index.js';
import '@raruto/leaflet-elevation/src/index.css';
const map = L.map('map', {
center: [41.4583, 12.7059]
zoom: 5,
});
const controlElevation = L.control.elevation({
// CHANGE ME: with your own http server folder (eg. "http://custom-server/public/path/to/leaflet-elevation/src/")
srcFolder: 'http://unpkg.com/@raruto/leaflet-elevation/src/'
}).addTo(map);
// Load track from url (allowed data types: "*.geojson", "*.gpx", "*.tcx")
controlElevation.load("https://raruto.github.io/leaflet-elevation/examples/via-emilia.gpx");
```
