How to stack bar from data with x and y in Chart JS
1
I am trying to plot a stack bar with data having the x and y values, eg {x: 1, y:1}.
But it seems that Chart JS follows indexing of array passed in the data with the index in the labels not the x.
I also tried using ticks: {source: 'data'} but no use.
I had to uncomment the labels: on and add index 1 and 2 in Africa dataset to see desired results.
Is there some way?
<canvas id="barchart" width="800" height="450"></canvas>
<script>
var ctx = document.getElementById("barchart").getContext('2d');
var barchart = new Chart(ctx, {
type: 'bar',
data: {
//labels: [0,1,2,3],
datasets: [{
data: [{x: 0, y: 2}, {x: 3, y: 1}],
label: "Africa",
backgroundColor: "#3e95cd",
fill: false
}, {
data: [{x: 0, y: 1}, {x: 1, y: 1}, {x: 2, y: 1}, {x: 3, y: 2}],
label: "Asia",
backgroundColor: "#8e5ea2",
fill: false
}, {
data: [{x: 0, y: 1}, {x: 1, y: 1}, {x: 2, y: 1}, {x: 3, y: 1}],
label: "Europe",
backgroundColor: "#3cba9f",
fill: false
}, {
data: [{x: 0, y: 1}, {x: 1, y: 1}, {x: 2, y: 1}, {x: 3, y: 1}],
label: "Latin America",
backgroundColor: "#e8c3b9",
fill: false
}, {
data: [{x: 0, y: 1}, {x: 1, y: 1}, {x: 2, y: 1}, {x: 3, y: 1}],
label: "North America",
backgroundColor: "#c45850",
fill: false
}
]
},
options: {
legend: { display: false },
title: {
display: true,
text: 'Predicted world population (millions) in 2050'
},
responsive: false,
maintainAspectRatio: false,
scales: {
xAxes: [{
stacked: true,
ticks: {source: 'data'}
}],
yAxes: [{
stacked: true
}]
}
}
});
</script>
