Chartjs v2.0: stacked bar chart - chart.js

Question

I need to get a chart like this:
I find this example but it uses old version of ChartJs. I try it using v2.0 but I don't get it.
Can someone post a example?

Answer 1

With v2.1.x, you can achieve this using the stacked option
...
options: {
scales:{
xAxes: [{
stacked: true
}],
yAxes: [{
stacked: true
}]
}
}
...

Answer 2

After fiddling forever, I finally got it to work, here's a sample. Somebody please update the docs!
var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes 1',
data: [10, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(255, 99, 132, 0.2)',
'rgba(255, 99, 132, 0.2)',
'rgba(255, 99, 132, 0.2)',
'rgba(255, 99, 132, 0.2)',
'rgba(255, 99, 132, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(255,99,132,1)',
'rgba(255,99,132,1)',
'rgba(255,99,132,1)',
'rgba(255,99,132,1)',
'rgba(255,99,132,1)'
],
borderWidth: 2
},
{
label: '# of Votes 2',
data: [15, 19, 3, 5, 2, 3],
backgroundColor: [
'rgba(255, 159, 64, 0.2)',
'rgba(255, 159, 64, 0.2)',
'rgba(255, 159, 64, 0.2)',
'rgba(255, 159, 64, 0.2)',
'rgba(255, 159, 64, 0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255, 159, 64, 1)',
'rgba(255, 159, 64, 1)',
'rgba(255, 159, 64, 1)',
'rgba(255, 159, 64, 1)',
'rgba(255, 159, 64, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 2
}
]
},
options: {

Answer 3

Just make sure that you provide an array of object(s), not just one object for xAxis and yAxis.
"options": {
"scales": {
"xAxes": [
{
"stacked": true
}
],
"yAxes": [
{
"stacked": true
}
]
}
}
