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
