Google charts dashboard loads only if I right click on inspect element - google-visualization

I want to show some dashboard charts (like these ones), for example one PieChart and one BarChart.
The issue I have found is that these charts aren't displayed unless, I right click on Inspect element. And viceversa, if I have the inspect element tools already open, the charts aren't display either until I close the inspect elements tools.
I am using bootstrap, slim framework and eloquent orm.
In the case of the pieChart, the sample data displayed is the following:
[
{
Area: "Actores y Procesos Sociales",
Cantidad: 49
},
{
Area: "Población y Estudios Demográficos",
Cantidad: 41
},
{
Area: "Estudios Agrarios",
Cantidad: 40
},
{
Area: "Instituciones Políticas",
Cantidad: 35
},
{
Area: "Sociedad y Cultura",
Cantidad: 30
},
{
Area: "Estudios Urbanos y Regionales",
Cantidad: 26
},
{
Area: "Estudios de la Educación y la Ciencia",
Cantidad: 23
}
]
Here is the code for both the PieChart and the BarChart:

Why is this happening? What should I fix so that those charts are displayed just after opening the URI in the browser?
Solved
The problem was in this part where there is this function resizeHandler():
I had:
dashboard2.bind(control2,chart);
/*http://stackoverflow.com/a/18984903/1883256*/
function resizeHandler () { /*This helps make the chart responsive*/
dashboard2.draw(data);
}
if (window.addEventListener) {
window.addEventListener('resize', resizeHandler, false);
}
else if (window.attachEvent) {
window.attachEvent('onresize', resizeHandler);
}
Instead of:
dashboard2.bind(control2,chart);
dashboard2.draw(data);
/*http://stackoverflow.com/a/18984903/1883256*/
function resizeHandler () {/*This helps make the chart responsive*/
dashboard2.draw(data);
}
if (window.addEventListener) {
window.addEventListener('resize', resizeHandler, false);
}
else if (window.attachEvent) {
window.attachEvent('onresize', resizeHandler);
}
So, I had to repeat the call of the dashboard.draw(data); both inside the function resizeHandler() and outside it, below the dashboard.bind() function.

first, setOnLoadCallback should only be called once per page load
and you can include the 'callback' in google.charts.load
try replacing this...
google.charts.load('current', {'packages':['corechart','table','controls'],'language': 'es'});
google.charts.setOnLoadCallback(proyectosporarea);
google.charts.setOnLoadCallback(institucionesPporproyecto);
with this...
google.charts.load('current', {
'callback': function () {
proyectosporarea();
institucionesPporproyecto();
},
'packages': ['corechart','table','controls'],
'language': 'es'
});
next, each wrapper object needs a dom element
in function proyectosporarea, the objects appear to have the wrong containerId
see comments in the following snippet...
var donutRangeSlider = new google.visualization.ControlWrapper({
'controlType': 'NumberRangeFilter',
'containerId': 'filter_div', //<-- should = numberRangeFilter_control_div
'options': {
'filterColumnLabel': 'Cantidad'
}
});
// Create a pie chart, passing some options
var pieChart = new google.visualization.ChartWrapper({
'chartType': 'PieChart',
'containerId': 'chart_div', //<-- should = numberRangeFilter_chart_div
'options': {
title: 'Número de proyectos vigentes por área de investigación (total: '+totalproyectos+')',
backgroundColor: { fill:'transparent'},
height: 500,
}

How to add vertical lines and annotations Google timeline chart

I am using a google timeline similar to the code snippet below. I want my chart to look like the one below. I have managed to get everything to work expect how to add the dashed lines and text notation. Unfortunately, when I am searching for annotations I keep getting the AnnotatedTimeline, which is a different google chart.
Is there a simple way to do this?
<html>
<head>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<script type="text/javascript">
google.charts.load('current', {'packages':['timeline']});
google.charts.setOnLoadCallback(drawChart);
function drawChart() {
var container = document.getElementById('timeline');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({ type: 'string', id: 'President' });
dataTable.addColumn({ type: 'date', id: 'Start' });
dataTable.addColumn({ type: 'date', id: 'End' });
dataTable.addRows([
[ 'Washington', new Date(1789, 3, 30), new Date(1797, 2, 4) ],
[ 'Adams', new Date(1797, 2, 4), new Date(1801, 2, 4) ],
[ 'Jefferson', new Date(1801, 2, 4), new Date(1809, 2, 4) ]]);
chart.draw(dataTable);
}
</script>
</head>
<body>
<div id="timeline" style="height: 180px;"></div>
</body>
</html>
I was able to get this to work by finding the position of the rects. I started by drawing divs for each line I would want to show. Then after the timeline is draw I repositions those divs based on the location of the rectangle. I was not able to get a good minimal working snippet here because of the window positions used in the snippet code, but I got pretty close. In my own code I have it working perfectly.

Is it possible to create context menu with chart.js?

I wanted to create a context menu on my line graph. When the user hovers across a point, they can right click and will see a context menu so that they can trigger more action.
Is this possible with chart.js?
Thanks,
Derek
AFAIK there is no native support for context menu from Chart.js, but you can create it using HTML and handle it.
This is an example:
var timestamp = [],
speed = [10, 100, 20, 30, 40, 100, 40, 60];
for (var k = speed.length; k--; k>0) {
timestamp.push(new Date().getTime()-60*60*1000*k);
}
var canvas = document.getElementById('chart');
var BB = canvas.getBoundingClientRect(),
offsetX = BB.left,
offsetY = BB.top;
var ctx = canvas.getContext("2d");
var data = {
labels: timestamp,
datasets: [{
data: speed,
label: "speed",
backgroundColor: ['rgba(0, 9, 132, 0.2)'],
borderColor: ['rgba(0, 0, 192, 1)'],
borderWidth: 1,
}
]
};
var options = {
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
}
}],
xAxes: [{
type: 'time',
}]
}
};
var chart = new Chart(ctx, {
type: 'line',
data: data,
options: options
});
var $menu = $('#contextMenu');
canvas.addEventListener('contextmenu', handleContextMenu, false);
canvas.addEventListener('mousedown', handleMouseDown, false);
function handleContextMenu(e){
e.preventDefault();
e.stopPropagation();
var x = parseInt(e.clientX-offsetX);
var y = parseInt(e.clientY-offsetY);
$menu.css({left:x,top:y});
$menu.show();
return(false);
}
function handleMouseDown(e){
$menu.hide();
}
menu = function(n){
console.log("select menu "+n);
$menu.hide();
}
#chart {
width: 100%;
height: 100%;
}
#contextMenu{
position:absolute;
border:1px solid red;
background:white;
list-style:none;
padding:3px;
}
.menu-item:hover {
background: #dddddd;
text-decoration: underline;
cursor: pointer;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.7.2/Chart.bundle.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id=canvasContainer>
<canvas id="chart"></canvas>
<ul id="contextMenu" style="display:none;">
<li class="menu-item" onclick="menu(1)">Menu 1</li>
<li class="menu-item" onclick="menu(2)">Menu 2</li>
</ul>
</div>
For anyone looking for this, #beaver's answer does not have access to the clicked item (data point), you can save the state in onHover and use it in contextmenu.
options: {
events: ['click', 'mousemove'],
onHover: function(e, fields){
const lx = e.layerX;
const bars = fields.filter(({_view: {x,width}}) => (x - width/2) <= lx && lx <= (x + width/2));
const data = bars.map(({_index, _datasetIndex}) => this.data.datasets[_datasetIndex].data[_index]);
this.hoveredItem = {bars, data, fields};
},
},
plugins: [
{
afterInit: (chart) =>
{
var menu = document.getElementById("contextMenu");
chart.canvas.addEventListener('contextmenu', handleContextMenu, false);
chart.canvas.addEventListener('mousedown', handleMouseDown, false);
function handleContextMenu(e){
e.preventDefault();
e.stopPropagation();
menu.style.left = e.clientX + "px";
menu.style.top = e.clientY + "px";
menu.style.display = "block";
console.log(chart.hoveredItem);
return(false);
}
function handleMouseDown(e){
menu.style.display = "none";
}
}
}

Please help me.

Use the 'statechange' event listener to determine when values are selected...
Then compPicker.getState().selectedValues to get the selected values in an array...
google.charts.load('current', {
callback: drawVisualization,
packages: ['controls', 'corechart', 'table']
});
function drawVisualization() {
var jsonData = '{"cols":[{"label":"Subject","type":"string"},{"label":"pete","type":"number"},{"label":"john","type":"number"},{"label":"carl","type":"number"},{"label":"andrea","type":"number"}],"rows":[{"c":[{"v":"coolness"},{"v":4.4},{"v":4.3},{"v":3.1},{"v":4.3}]},{"c":[{"v":"sexyness"},{"v":4.2},{"v":3.8},{"v":3.6},{"v":4.8}]},{"c":[{"v":"toughness"},{"v":3.1},{"v":2.7},{"v":2.4},{"v":2.9}]},{"c":[{"v":"chillnes"},{"v":4.4},{"v":4.4},{"v":4.2},{"v":4.5}]},{"c":[{"v":"madness"},{"v":4.6},{"v":4.6},{"v":4},{"v":4.6}]},{"c":[{"v":"lochness"},{"v":3.9},{"v":3.7},{"v":2.9},{"v":3.9}]},{"c":[{"v":"extraness"},{"v":4.6},{"v":4.3},{"v":3.6},{"v":4.3}]}]}';

Combining two types of Category Filter in Google Charts API

I wanted to enable users to filter the results being displayed on the chart. Google API provides CategoryFilter which enforces filtering by rows. Here is my code which works perfectly fine
<html>
<head>

// Set a callback to run when the Google Visualization API is loaded.

function drawChart() {
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(<?=$jsonTable?>);
var countryPicker = new google.visualization.ControlWrapper({
controlType: 'CategoryFilter',
containerId: 'negeri',
dataTable: data,
options: {
filterColumnLabel: 'Negeri',
ui: {
labelStacking: 'vertical',
allowTyping: false,
allowMultiple: true
}
},
// Define an initial state, i.e. a set of metrics to be initially selected.
state: {'selectedValues': ['Kedah', 'Johor']}
});
var chart = new google.visualization.ChartWrapper({
chartType: 'ColumnChart',
containerId: 'chart_div',
options: {
title: 'Statistik Negeri vs. Kategori Sukan',
width: 1000,
height: 1000,
hAxis: {title: 'Negeri', titleTextStyle: {color: 'blue'}},
vAxis: {title: 'Jumlah Kategori', titleTextStyle: {color: 'blue'}}
}
});
// Create the dashboard.
new google.visualization.Dashboard(document.getElementById('dashboard')).
// Configure the controls so that:
// - the 'Country' selection drives the 'Region' one,
// - the 'Region' selection drives the 'City' one,
// - and finally the 'City' output drives the chart
bind(countryPicker, chart).
// Draw the dashboard
draw(data);
}
</script>
</head>
<body>
<div id="dashboard">
<div id="negeri"></div>
<div id="chart_div"></div>
</div>
</body>
</html>
However in my datatable, I would also want to filter by columns. These two types of filtering should work together. (dependent; by bind() function). I have referred to #asgallant http://jsfiddle.net/asgallant/WaUu2/ and that is the feature that I wanted to combine with.
How can I possibly combine them? I have tried combining setChartView() by #asgallant with google's dashboard() but it's not working.

You want to bind your countryPicker filter to the chart as normal, but do not bind the columnFilter control to anything - the setChartView function handles everything for the columnFilter. You need to tweak a couple other lines to make it work with a dashboard, but nothing major. This is what it should look like:
function drawChart() {
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(<?=$jsonTable?>);
var columnsTable = new google.visualization.DataTable();
columnsTable.addColumn('number', 'colIndex');
columnsTable.addColumn('string', 'colLabel');
var initState= {selectedValues: []};
// put the columns into this data table (skip column 0)
for (var i = 1; i < data.getNumberOfColumns(); i++) {
columnsTable.addRow([i, data.getColumnLabel(i)]);
// you can comment out this next line if you want to have a default selection other than the whole list
initState.selectedValues.push(data.getColumnLabel(i));
}
var countryPicker = new google.visualization.ControlWrapper({
controlType: 'CategoryFilter',
containerId: 'negeri',
dataTable: data,
options: {
filterColumnLabel: 'Negeri',
ui: {
labelStacking: 'vertical',
allowTyping: false,
allowMultiple: true
}
},
// Define an initial state, i.e. a set of metrics to be initially selected.
state: {'selectedValues': ['Kedah', 'Johor']}
});
var columnFilter = new google.visualization.ControlWrapper({
controlType: 'CategoryFilter',
containerId: 'colFilter_div',
dataTable: columnsTable,
options: {
filterColumnLabel: 'colLabel',
ui: {
label: 'Kategori Sukan',
allowTyping: false,
allowMultiple: true,
allowNone: false,
selectedValuesLayout: 'belowStacked'
}
},
state: initState
});
var chart = new google.visualization.ChartWrapper({
chartType: 'ColumnChart',
containerId: 'chart_div',
options: {
title: 'Statistik Negeri vs. Kategori Sukan',
width: 1000,
height: 1000,
hAxis: {title: 'Negeri', titleTextStyle: {color: 'blue'}},
vAxis: {title: 'Jumlah Kategori', titleTextStyle: {color: 'blue'}}
}
});
// Create the dashboard.
var dashboard = new google.visualization.Dashboard(document.getElementById('dashboard')).
bind(countryPicker, chart);
function setChartView () {
var state = columnFilter.getState();
var row;
var view = {
columns: [0]
};
for (var i = 0; i < state.selectedValues.length; i++) {
row = columnsTable.getFilteredRows([{column: 1, value: state.selectedValues[i]}])[0];
view.columns.push(columnsTable.getValue(row, 0));
}
// sort the indices into their original order
view.columns.sort(function (a, b) {
return (a - b);
});
chart.setView(view);
chart.draw();
}
google.visualization.events.addListener(columnFilter, 'statechange', setChartView);
var runOnce = google.visualization.events.addListener(dashboard, 'ready', function () {
google.visualization.events.removeListener(runOnce);
setChartView();
});
columnFilter.draw();
dashboard.draw(data);
}
google.load('visualization', '1', {packages:['corechart'], callback: drawChart});
