<p>In this tutorial, we will see examples of using the Chartjs JavaScript library to create bar charts.</p>
<p>This quick example gives you the code to display a simple bar chart on the browser.</p>
<p>The below JavaScript code shows how to include and initiate the ChartJS library. It uses static data to set the bar chart labels and dataset in JavaScript.</p>

</code></pre>
</div>
<p><strong>Output:</strong></p>
<p>This example sets the chart parameters to the ChartJS <em>data</em> and the <em>options</em> array and displays the following bar chat to the browser.</p>
<p>This is a very easy client-side solution to display professional graphical representation in the form of a bar chart.</p>
<p>You can simply use this code in your project by tweaking the data points slightly.</p>

<h2>Example 2: Horizontal bar chart</h2>
<p>This library supports creating both vertical and horizontal bar charts. But, the default is the vertical bar chart.</p>
<p>In this example, it creates a horizontal bar chart using the ChartJS plugin.</p>
<p>For the vertical or horizontal bar charts, the direction depends on the <em>indexAxis</em> option.</p>
<p>This example sets <em>indexAxis=’y’</em> to display the bars horizontally.</p>

<p>Previously, we used this JS library to create a pie chart using this ChartJS library. But, it is not supporting to display of 3D pie charts. See the linked article that uses <a href="https://phppot.com/javascript/chartjs-pie-chart/">Google charts for creating the 3D pie chart</a>.</p>

<p>Grouped bar charts are useful for showing a comparative reading.</p>

<p>Also, it supports generating more types of charts. The <em>type</em> parameter is used to define the type of the chart.</p>
