0















So im creating charts in javascript using chartjs , i have a problem that how can i select each bar in bar chart and launch a modal with its data.



I already tried the onClick event after options , but i think i have a wrong pattern. I dont know much more about chartjs and i think i need help. Here's my code :



  var ctx = document.getElementById("myChart2").getContext('2d');
var myChart = new Chart(ctx, {
type: 'horizontalBar',
data: {
labels: outlet,
datasets: [{
label: "Players",
data: total_outlet,
backgroundColor: [
"#f38b4a",
"#56d798",
"#ff8397",
"#6970d5",
"#ff0000",
"#339966",
"#004d00",
"#003366",
"#e62e00",
"#666633",
"#996633"
],
hoverBackgroundColor: [
"#f38b4a",
"#56d798",
"#ff8397",
"#6970d5",
"#ff0000",
"#339966",
"#004d00",
"#003366",
"#e62e00",
"#666633",
"#996633"
],
borderWidth: 1
}]
},
options: {
scales: {
xAxes: [{
ticks: {
min: 0,
fontColor: "white"
},
gridLines: {
display:false
}
}],
yAxes:[{
ticks: {
fontColor: "white"
},
gridLines: {
display:false
}
}]
},

title: {
display: true,
text: 'Top 10 Outlet with Active UGL Terminals',
fontColor: "white"
},
legend: {
display:false,
labels: {
fontColor: "white"

}
}

          This is quite straightforward and is documented at the Chart.js API page. Below is a working snippet adapted from the official example:






          let canvas = document.getElementById('canvas');

          let myChart = new Chart(canvas, {
          type: 'bar',
          data: {
          labels: ['a', 'b', 'c', 'd'],
          datasets: [{
          data: [0, 2, 4, 8]
          }]
          }
          });

          canvas.addEventListener('click', function(evt) {
          var firstPoint = myChart.getElementAtEvent(evt)[0];
          if (firstPoint) {
          var label = myChart.data.labels[firstPoint._index];
          var value = myChart.data.datasets[firstPoint._datasetIndex].data[firstPoint._index];

          alert('Label: ' + label + "nValue: " + value);
          }
          });
