[Chartjs]-Horizontal Bar-Chart in angular-chart.js

âś…

Under the hood angular-chart.js uses chart.js, which does not have native support for horizontal bar charts. That said, there is a horizontal bar chart plugin that can be added to support this type of chart: https://github.com/tomsouthall/Chart.HorizontalBar.js

I believe that to make this work, you will need to use the dynamic chart directive

<canvas id="base" class="chart-base" chart-type="type"
  chart-data="data" chart-labels="labels" chart-legend="true">
</canvas>

And then specify the type as HorizontalBar.

for those wondering here later; there are new versions of chart.js and angular-chart.js available. Chart.js 2.1 and later support horizontal charts, angular-chart.js has a new branch to work with the latest chart.js version see the github repo here.

Using this version does not require the above mentioned HorizontalBar plugin by Tom Southall.

Use the samples available at the above angular-chart.js site, and make sure to set the value of the class attribute to “chart-horizontalBar”.

<canvas id="HorizontalBar" class="chart chart-horizontalBar" chart-data="data" chart-labels="labels" chart-series="series"></canvas>

I don’t think there is a need to include Chart.HorizontalBar.js now. This is how to get a simple horizontal bar chart in Angular using chart.js-

HTML-

<div>
    <canvas id="bar-chart-horizontal" width="800" height="450"></canvas>
</div>

JS controller-

var myChart = new Chart(document.getElementById("bar-chart-horizontal"), {
        type: 'horizontalBar',
        data: {
          labels: ["Africa", "Asia", "Europe", "Latin America", "North America"],
          datasets: [
            {
              label: "Population (millions)",
              backgroundColor: ["#ff0000", "#8e5ea2","#3cba9f","#454545","#c45850"],
              data: [2478,5267,734,784,433]
            }
          ]
        },
        options: {
          legend: { display: false },
          title: {
            display: true,
            text: 'Predicted world population (millions) in 2050'
          }
        }
    });
