What is Angular Chart JS?

Angular Chart JS is a powerful and feature-packed library that allows developers to create beautiful and interactive charts for their web applications using AngularJS. The library is built on top of Chart.js and provides a simple and easy-to-use API that can be used to create a wide range of charts, including line, bar, pie, doughnut, radar, and more.

How to use Angular Chart JS?

To use Angular Chart JS, you first need to include the library in your project. You can either download it from the official website or install it using bower or npm. Once you have included the library in your project, you can use the "angular-chart.js" module in your AngularJS application to start using the library.

To create a chart using Angular Chart JS, you need to define a chart element in your HTML code and specify its type, data, and options. For example:

<canvas id="myChart" chart-type="line" chart-data="data" chart-options="options"></canvas>

In the above code, we have defined a canvas element with an ID of "myChart". We have also specified the chart type as "line", the data as "data", and the options as "options". These values can be defined in your controller or service using the following code:

$scope.data = {
  labels: ["January", "February", "March", "April", "May", "June", "July"],
  datasets: [
    {
      label: "My First dataset",
      data: [65, 59, 80, 81, 56, 55, 40]
    }
  ]
};

$scope.options = {
  responsive: true,
  title: {
    display: true,
    text: 'My Chart'
  },
  scales: {
    yAxes: [{
      ticks: {
        beginAtZero:true
      }
    }]
  }
};

In the above code, we have defined the data and options for our chart. The "labels" array represents the x-axis labels for our chart, while the "datasets" array represents the data for our chart. In this case, we have only defined one dataset with the label "My First dataset" and some sample data.

The options object allows us to customize various aspects of our chart, such as its title, axis labels, colors, and more. In this case, we have specified that our chart should be responsive and should have a title of "My Chart". We have also defined the y-axis ticks to start at zero.

Alternative ways to use Angular Chart JS

Apart from using the "canvas" element, you can also use other HTML elements like "div" or "svg" to create your charts. The library provides a range of directives that can be used to define these elements and customize their behavior. For example:

<div chart-line chart-data="data" chart-options="options"></div>

The above code creates a line chart using a "div" element instead of a "canvas" element. The "chart-line" directive specifies the chart type, and the "chart-data" and "chart-options" attributes are used to define the chart data and options.

Similarly, you can use the "chart-bar", "chart-pie", "chart-doughnut", and other directives to create different types of charts. You can also customize the appearance and behavior of your charts using various attributes and options provided by the library.
