I am replicating Google Analytics Embed API demos, which you can find here. So far, I have been able to replicate the basic dashboard, multiple date ranges, multiple views and interactive charts using my clientid
The one that is giving me trouble is the Third Party Visualizations and I am following the steps according to what is posted.
By the way for step 3 I am using the full path "https://ga-dev-tools.appspot.com/public/..."
Once I log in with my Google Account, all I get is the embed-api-auth-container but not the charts. I am using the following code:

The example code you linked to is missing some elements and needs to be updated.
Check out this bug on Github which has a workaround and allows you to track the progress of the fix:

Unable to Draw a curved polyline using Here Maps JS API.
Trying to add the logic based on my previous findings.
It throws an error "Uncaught TypeError: arc.GreatCircle is not a constructor"
Any Suggestions on how to fix this ?
My Earlier Querstion
Here is my working JSFiddle which is trying to draw a curve to multiple spots.
//Step 1: initialize communication with the platform
// In your own code, replace variable window.apikey with your own apikey
var platform = new H.service.Platform({
apikey: window.apikey
});
var defaultLayers = platform.createDefaultLayers();
//Step 2: initialize a map - this map is centered over Europe
var map = new H.Map(document.getElementById('map'),
defaultLayers.vector.normal.map,{
center: {lat:52, lng:5},
zoom: 5,
pixelRatio: window.devicePixelRatio || 1
});
// add a resize listener to make sure that the map occupies the whole container
window.addEventListener('resize', () => map.getViewPort().resize());
//Step 3: make the map interactive
// MapEvents enables the event system
// Behavior implements default interactions for pan/zoom (also on mobile touch environments)
var behavior = new H.mapevents.Behavior(new H.mapevents.MapEvents(map));
// Create the default UI components
var ui = H.ui.UI.createDefault(map, defaultLayers);
window.addEventListener('resize', function() { map.getViewPort().resize(); });
var npoints = 100,
offset = 20;
// Now use the map as required...

this is simple: the var GreatCircle is not defined yet but program code invoke GreatCircle
We moved some parts of code through each together
but any way there is error GreatCircle doesn't have 'arc' property defined.
there is this module https://demo.support.here.com/javascripts/examples/v31/geodesic-polyline.js
but you needs Bézier curve: https://en.wikipedia.org/wiki/B%C3%A9zier_curve
I found some implementation on this https://habr.com/ru/post/163073/ - (but in russian) - there a curve consists from lines based on 100 points (step 0.01)
flow = getBezierCurve(new Array(arr[0], arr[1], arr[2], arr[3]), 0.01);
drawLines(ctx, flow, 10);
In JS API wasn't implemented functionality of like Bézier curve
but search in google on "bezier curve javascript example code" - if you get points of curve you can use in JS API map.screenToGeo every point and plot it on the map
I am having a problem in building a pie chart with chart.js ..I am working in wix.com ..The problem i am facing is with 2 postmessage()..

var labels = [];
for (var i = 0; i <= res.length - 1; i++) {
data.push(res[i].Minutes.toString());
labels.push(res[i].champion.toString());

On doing this..i am getting the result like this..
Result
I am getting the chart with the data array..but the labels is undefined..
And if i unquote the postmessage(labels) and send both data and labels via 2 postmessage()..the chart don't form...
I need to send both data and labels array to the iframe from page code...
Any solution?????
This is easiest done by sending both the data and the labels from your page code in one object. Then in the HTML element, you can set the chart's data and labels using that object.
In your case, that would look something like this:
Page Code:
let info = {data:data, labels:labels};
$w("#html1").postMessage(info);
HTML Element Code:
window.onmessage = function(event){
myChart.data.datasets[0].data = event.data.data;
myChart.data.labels = event.data.labels;
myChart.update();
};
You are right! This is the easiest way.
Here is the page code...
var data = [];
for (var i = 1; i < 7; i++) {
var _temp = Math.log10(i);
data.push(_temp);
}
var labels = ["September", "October", "Novemver", "December", "January", "February"];
$w.onReady(() => {
console.log("Data length: " + data.length);
console.log(data);
console.log("Label length: " + labels.length);
console.log(labels);
$w("#html1").onMessage((event) => {
let info = { data: data, labels: labels };
if (event.data.type === 'ready') {
$w("#html1").postMessage(info);
}
});
});

I'm using an auto-run block where I re-execute the same mongo with a few session variables ! loop over those doc , construct an array of events then I call the addEventSource and refetchResources function which are pretty expensive computationally ! the fullcalendar becomes slow the more data ! on every action the auto-run block is rerun ! what in your in your opinion can be done to speed things up ? I thought about only re-rendering the delta elements but this doesn't cover the deletion and update .

I am using Gridstack with Knockout.js. I am using http://troolee.github.io/gridstack.js/demo/knockout.html to create Gridstack widgets. I added a Google map in one of these widgets. The map appears with a scroll bar. Also, I need to have some kind of heading, as it is in its present state. The main problem is that the dimension of the map is fixed and when I resize the widget, the map does not fit in the widget automatically. Here is my full code:
ko.components.register('dashboard-grid', {
viewModel: {
createViewModel: function (controller, componentInfo) {
var ViewModel = function (controller, componentInfo) {
var grid = null;
this.widgets = controller.widgets;
this.id = controller.id;
this.afterAddWidget = function (items) {
if (grid == null) {
grid = $(componentInfo.element).find('.grid-stack').gridstack({
auto: false,
animate: true
}).data('gridstack');
}
var item = _.find(items, function (i) { return i.nodeType == 1 });
grid.addWidget(item);
ko.utils.domNodeDisposal.addDisposeCallback(item, function () {
grid.removeWidget(item);
});
};
};
return new ViewModel(controller, componentInfo);
}
},
template:
[
'<div class="grid-stack" data-bind="foreach: {data: widgets, afterRender: afterAddWidget}">',
' <div class="grid-stack-item" data-bind="attr: {\'data-gs-x\': $data.x, \'data-gs-y\': $data.y, \'data-gs-width\': $data.width, \'data-gs-height\': $data.height, \'data-gs-auto-position\': $data.auto_position}">',
' <div class="grid-stack-item-content" >',
' <header style="background-color: green;"> ',
' <button data-bind="click: $root.deleteWidget">Delete me</button><br>',
' <label><strong data-bind="text: $root.ids"></strong></label>',
' </header>',
' <div data-bind="attr: {id: $root.ids}">',
' </div>',
' </div>',
' </div>',
'</div> '
].join('')
});
$(function () {
var ids;
var Controller = function () {
var self = this;
this.widgets = ko.observableArray([]);
this.id = ko.observable("google-map");
this.ids = "";
this.addNewWidget = function () {
this.ids = this.id(); // this.ids is used to give id to div elements
this.widgets.push({
x: 0,
y: 0,
width:4,
height:5,
auto_position: true,
});
// calling method to draw map
createWidget(this.ids);
return false;
};
this.deleteWidget = function (item) {
self.widgets.remove(item);
return false;
};
};
ko.applyBindings(new Controller());
});
function createWidget(id) {
var dataArray, latitude, longitude, speed;
// Load the Visualization API and the corechart package.
try {
google.charts.load('current', {'packages':['map', 'gauge']});
// Set a callback to run when the Google Visualization API is loaded.
google.charts.setOnLoadCallback(drawChart);
}
catch ( err ) {
//console.log(err);
}
function drawChart() {
latitude = Number(12.93213);
longitude = Number(77.695185);
var mapOptions = {
showTooltip: true,
showInfoWindow: true,
zoomLevel: 16, // range: 0-21 for "roadmap" map type
mapType: 'roadmap',
enableScrollWheel: true,
draggable: false,
};
var coordinates = "Latitude : " + latitude + "\nLongitude : "+ longitude;
var mapData = google.visualization.arrayToDataTable([
['Lat', 'Long', 'Name'],
[latitude, longitude, coordinates]
] );
try {
//var chart = new google.visualization.Gauge(document.getElementById('gauge'));
var map = new google.visualization.Map(document.getElementById(id));
map.draw(mapData, mapOptions);
}
catch (err) {
console.log(err);

I created a map showing some restaurant in a particular area. I used fusion tables as data entry and the code generated to display this map:
here is the link
I tried with no luck to add a text label with the name of the restaurant near the placemark ( icon ) .
Any ideas on how I can do?
I searched a lot in the forums, but I didn't find a solution.
Thank you very much
JT

One option (for tables with less than a couple hundred rows) would be to query the table for the data using GViz and use that to add labels to the map.
