I'm trying to create a heatmap map with 2 layers using google maps API and heatmaps.js. I'm able to create my map by hard-coding my lat/lon variables, but ultimately I'd like to have my layers fed from JSON files that can easily be refreshed.
Here is my current HTML, which works great.

What I would like to do is replace var layer1 and layer2 with a single JSON file that I would be able to just query, I'm just unsure how to execute something like this. For example, a JSON file that would look something like this:
{
"datapoints": [
{
"lat": "38.1513366000",
"lon": "-97.4341659000",
"weight": "0",
"layer":"1"
},
{
"lat": "38.1513748000",
"lon": "-97.4341125000",
"weight": "0",
"layer":"1"
},
{
"lat": "38.1513938000",
"lon": "-97.4341125000",
"weight": "0",
"layer":"1"
},
{
"lat": "38.1493263000",
"lon": "-97.4339447000",
"weight": "0",
"layer":"1"
},
{
"lat": "38.1493339000",
"lon": "-97.4339447000",
"weight": "0",
"layer":"2"
},
{
"lat": "38.1493377000",
"lon": "-97.4339447000",
"weight": "0",
"layer":"2"
},
{
"lat": "38.1483650000",
"lon": "-97.4358291000",
"weight": "0",
"layer":"2"
},
{
"lat": "38.1484031000",
"lon": "-97.4358062000",
"weight": "0",
"layer":"2"
}
]
}

Alright, almost there I think. Thanks so much for your help so far, I know this is painful. Here is my initialize function, I'm still getting Uncaught ReferenceError: layers is not defined
<script type='text/javascript'>
var map, pointarray, heatmap;
function initialize() {
function loadData() {
var layers = [ ];
$.ajax({
url: 'testdata.json',
async: false,
dataType: 'json',
success: function (data) {
for (var i=0; i<data.datapoints.length; i++) {
var datapoint = data.datapoints[i];
if (layers[datapoint.layer]===undefined) {
layers[datapoint.layer] = [];
}
layers[datapoint.layer].push({
location: new google.maps.LatLng(datapoint.lat, datapoint.lon),
weight: datapoint.weight,
layerID: datapoint.layer
});
}
}
});
return layers;
}
var mapOptions = {
zoom: 4,
center: new google.maps.LatLng(38.82, -99.408660),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
pointArray1 = new google.maps.MVCArray(layers[1]);
pointArray2 = new google.maps.MVCArray(layers[2]);
heatmap1 = new google.maps.visualization.HeatmapLayer({
data: pointArray1
});
heatmap2 = new google.maps.visualization.HeatmapLayer({
data: pointArray2
});
heatmap1.setMap(map);
heatmap2.setMap(map);
}
//FUNCTION TO CHANGE LAYERS
function changeMap(layerNum) {
if (layerNum == 1) {
updateMap(heatmap1);
}
if (layerNum == 2) {
updateMap(heatmap2);
}
}
//FUNCTION TO UPDATE LAYERS
function updateMap(layer) {
var layerMap = layer.getMap();
if (layerMap) {
layer.setMap(null);
} else {
layer.setMap(map);
}
}
</script>
You'll need a way of reading that JSON and parsing it into the variable(s) you need. Since you're using jQuery, here's a method that would work with the JSON structure you have.
$.getJSON("layers.json").then(function(data) {
$.each(data, function(i,datapoints) {
$.each(datapoints, function(j,datapoint) {
layers.push({
location: new google.maps.LatLng(datapoint.lat, datapoint.lng),
weight: datapoint.weight,
layerID: datapoint.layer
});
});
});
});
Adapt as necessary.
In response to davids12's update, here's a function that returns an array of arrays where each composite array has the datapoints from a certain layer. So, running over your example, layers would have 2 arrays in it (layers[1] and layers[2]) which are basically layer1 and layer2 that you describe in your code (with an additional layerID variable; you could remove it if you wish). This allows you to load much more layers and points just by putting them in the JSON using the format you have now.
function loadData() {
var layers = [ ];
$.ajax({
url: 'j.json',
async: false,
dataType: 'json',
success: function (data) {
for (var i=0; i<data.datapoints.length; i++) {
var datapoint = data.datapoints[i];
if (layers[datapoint.layer]===undefined) {
layers[datapoint.layer] = [];
}
layers[datapoint.layer].push({
location: new google.maps.LatLng(datapoint.lat, datapoint.lng),
weight: datapoint.weight,
layerID: datapoint.layer
});
}
}
});
return layers;
}

I wrote an AJAX Javascript code for my ESP32 datalogger which worked so far using old versions of Chart.js. The website hosted by the ESP32 is not working anylonger if I use a more recent of Chart.js.
The error message I caught is:
Uncaught ReferenceError: Chart is not defined at datalogin.html
The line in the code involved is this one
const myChart = new Chart(ctx, config);
Something in the interpretation seems to occur at a very early stage. But I could not identify what. See code below.
I already tried different Chart.js repository in order to have it working. It had absolutly no influence. I actively looked using different browser regarding this specific problematic and I could not find any way of solving this problem.
Thanks a lot for your support

I'm writing my first web component with Stencil.
It's a pills component published here : https://github.com/reservoir-dogs/rp-pills
The component code's :
import { Component, Prop, Watch, Event, EventEmitter } from '#stencil/core';
#Component({
tag: 'rp-pills',
styleUrl: 'rp-pills.scss',
shadow: false
})
export class RpPills {
#Prop() items: any[] = [];
#Prop() displayProperty: string;
#Prop({ mutable: true }) value: any;
#Prop() class: string;
#Prop() theme: string = 'default';
#Prop() emptyMessage: string = 'No item';
classes: string;
#Event() valueChange: EventEmitter;
onClick(item: any) {
this.value = item;
this.valueChange.emit(this.value);
}
#Watch('class')
#Watch('theme')
watchHandler() {
this.classes = `nav nav-pills ${this.theme} ${this.class}`;
}
render() {
if (this.items.length > 0)
return (
<ul class={this.classes}>
{this.items.map((item) =>
<li onClick={() => this.onClick(item)} class={this.value === item ? 'active' : ''} >
<a>{item[this.displayProperty]}</a>
</li>)}
</ul>
);
else
return (
<ul class={this.classes}>
<li class="empty">
<a>{this.emptyMessage}</a>
</li>
</ul>
);
}
}
This test work fine :
it('should work with a list of items and selected item', async () => {
const cmp = new RpPills();
cmp.valueChange = {
emit: () => { }
};
const spy = jest.spyOn(cmp.valueChange, 'emit');
cmp.onClick({name:'Coucou'});
expect(spy).toHaveBeenCalledWith({ name: 'Coucou' });
});
But my HTML sample and an integration in Ionic App does not work and return the following message : {"isTrusted":false}

I tried to do that :
<rp-pills [items]="jeux" [(value)]="partie.jeu"></rp-pills>
The event of my Stencil component's :
is not compliant with angular two-way binding
contain a property 'detail' where there is my value
Use in Ionic App
HTML code
<rp-pills [items]="jeux" [value]="partie.jeu" (valueChange)="jeuChange($event.detail)"></rp-pills>
TypeScript code
jeuChange(jeu: Jeu) {
this.partie.jeu = jeu;
}
The reequirement is to make an RTL picker with multiple levels.
I copied the example from the documentation into a page equiped with the official frameworks' CSS for RTL users.
I have modified "textAlign" properties of each column as well.
For some reason the picker isn't acting as expected. open the snippet in full page mode.
var app = new Framework7({
root: '#app',
rtl: true,
theme: 'md'
});
app.views.create('#mainView', {
});
var carVendors = {
Japanese: ['Honda', 'Lexus', 'Mazda', 'Nissan', 'Toyota'],
German: ['Audi', 'BMW', 'Mercedes', 'Volkswagen', 'Volvo'],
American: ['Cadillac', 'Chrysler', 'Dodge', 'Ford']
};
var pickerDependent = app.picker.create({
inputEl: '#demo-picker-dependent',
rotateEffect: true,
formatValue: function(values) {
return values[1];
},
cols: [{
textAlign: 'right',
values: ['Japanese', 'German', 'American'],
onChange: function(picker, country) {
if (picker.cols[1].replaceValues) {
picker.cols[1].replaceValues(carVendors[country]);
}
}
},
{
textAlign: 'right',
values: carVendors.Japanese,
width: 160,
},
],
routableModals:false
});

That seems like a bug in Framework7.
CSS 'right' and 'left' properties for first and last '.picker-column' don't fit RTL layout (flipped). The attached repair solved it.
var app = new Framework7({
root: '#app',
rtl: true,
theme: 'md'
});
app.views.create('#mainView', {
});
var carVendors = {
Japanese: ['Honda', 'Lexus', 'Mazda', 'Nissan', 'Toyota'],

EDIT:

I am trying to withdraw data from a google spreadsheet, convert it into a DataTable and push the values into a Dashboard LineChart according to Google Apps documentation. I have managed to do this with an array I manually populated but I have not managed to figure out how to do this properly with a spreadsheet. It currently states that one or more participants failed to draw and I have an invalide column label. Any ideas what I am doing wrong.

I'm trying to use MEAN stack store and update a simple angular to do list, I've write a restful api for server.the post record function app.addTask = function(task) working fine if I remove $http.get from html, but once put it back, it stop record the new task.
Can't figure it out why, need your guys help.
Here is the server.js
var express = require('express'),
restful = require('node-restful'),
bodyParser = require('body-Parser'),
methodOverride = require('method-override'),
mongoose = restful.mongoose;
var app = express();
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(bodyParser.json());
app.use(methodOverride());
mongoose.connect('mongodb://localhost/transTaskDB');
//create new collection
var TaskSchema = mongoose.Schema({
contents: String,
target: String,
color: String,
status: Boolean
});
var Tasks = restful.model('tasks', TaskSchema);
// Tasks.methods(['get', 'post', 'put', 'delete']);
// Tasks.register(app, '/api/tasks');
// ROUTES FOR OUR API
//===============================================
var router = express.Router(); //get an instance of express Router
// middleware to use for all requests
router.use(function(req, res, next) {
// do logging
console.log('Shown when each request made.');
next(); // make sure we go to the next routes and don't stop here
});
//custom filter find the last entry record
//record new task
router.route('/newtask')
.post(function(req, res){
//create a new instance of the task model
var task = new Tasks();
task.contents = req.body.taskContent;
task.target = req.body.taskUser;
task.color = req.body.taskColor;
// task.contents = "have a tea";
// task.target = "tony";
// task.color = "#e74c3c";
task.status = false; //** fasle means the task still open not done
//task.save();
//throw error exception in console
task.save(function(err, tasks) {
if (err)
res.send(err);
res.json(tasks);
});
})
.get(function(req, res){
Tasks.find(function(err, tasks) {
if (err)
res.send(err);
res.json(tasks);
});
});
//REGISTER OUT ROUTES --------
//all of our route will be prefixed with /api
app.use('/api/tasks', router);
app.listen(3000);
console.log('Server is running at port 3000');
