  • Fetch and Display Advanced JSON Data in Chart JS
    In this video we will explore how to fetch and dusplay advanced JSON data in Chart.js. The goal is to explore how to get layers deep of JSON data and extract them as needed. We will be displaying the JSON data in Chart.js using async fetch. To do this we need to create a JSON file before we can use it with Chart.js.
    We will be fetching data and parsing JSON data so Chart.js can read it. Once you use the fetch command to extract the data from the file. The way we go around this is quite similar if we would connect to an outside JSON file based on an API which also needs fetch. The topic is quite complicated but we take it slow and make it easy to follow. However, it is worth to learn as this will open up many new doors.
    Let's explore this right now!

    ▬ About Us ▬▬▬▬▬▬▬▬▬▬▬▬
    Why we created these #chartjs and #javascript video tutorials?
    WHY
    Creating charts in javascript is very rewarding but extremely challenging. The Chart JS library made it easier to render charts. However the chart js documentation is hard to understand for many. It requires a lot of different moving parts to work along. The canvas tag, javascript, arrays and Chart JS all need to be combined to draw an eye catching bar chart or line chart.
    The videos explains the chart js documentation in a more visual and easy to understand way. You can follow along with the code and quickly grasp how it works. We cover the code in chart js but also what truly happens and why something happens when we write a line of code. This fundamental understanding gives clarity to you as a developer in chartjs. In short it is the Chart JS video documentation.
    HOW
    We answer questions from YOU (viewers) by creating an answer video that covers the questions YOU have posted in the comment section.
    WHAT
    Our goal is to help YOU learn how to draw charts in Chart JS by showing you in video format how to do it.
