I need to write text into the bar in chart using chart.js
var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'bar',
data:data,
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero:true
}
}]
}
},
responsive : true,
showTooltips : false,
showInlineValues : true,
centeredInllineValues : true,
tooltipCaretSize : 0,
tooltipTemplate : "<%= value %>"
});
the code above do not working...
i need something like this:
Add this code to your options object:
animation: {
onComplete: function () {
var chartInstance = this.chart;
var ctx = chartInstance.ctx;
console.log(chartInstance);
var height = chartInstance.controller.boxes[0].bottom;
ctx.textAlign = "center";
Chart.helpers.each(this.data.datasets.forEach(function (dataset, i) {
var meta = chartInstance.controller.getDatasetMeta(i);
Chart.helpers.each(meta.data.forEach(function (bar, index) {
ctx.fillText(dataset.data[index], bar._model.x, height - ((height - bar._model.y) / 2));
}),this)
}),this);
}
}

UPDATE 2
Surround your canvas with a container with your desired width and height
<div style="width: 100%; height: 500px">
<canvas id="myChart" width="400" height="400"></canvas>
</div>
and add the following into your options object
// Boolean - whether or not the chart should be responsive and resize when the browser does.
responsive: true,
// Boolean - whether to maintain the starting aspect ratio or not when responsive, if set to false, will take up entire container
maintainAspectRatio: false,
