▬ 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.

▬ Chart JS 4.1.2 ▬▬▬▬▬▬▬▬▬▬▬▬

Chart JS is a javascript library to draw charts in the canvas tag on your site. Presenting data in a visual manner such as charts is more effective and appealing. All the charts are always coded in the latest Chartjs version which is as of this recording Chart JS 4.1.2.

What type of charts can you make with Chart.JS?
With chart js you can make line chart, bar chart, pie chart, doughnut chart, scatter chart, polar area chart, radar chart, gauge chart and area chart. And with some clever tricks and visual adjustment more can be done.

I would like to see you do a Chart JS 4 video using a database such as MySQL. I done so using Flask and MariaDB but it was a bit tricky. I think many folks would like to see Chart JS used with "live" data.

how about manually input the data and after saving the data it will automatically creates a graph?

I appreciate what you are doing here - the code reorganization you present makes a lot of sense and since I am working on a new project that is a refactor of a Vue2 project using Chart.js 3, I can start fresh.

You should really attach the source code, though. It was actually quite difficult to figure out the code when you are moving chunks all over the place in the file and one can only see a small window into the code base. It took me at least 40 minutes to figure out what you were typing in at the end. If you had the source code to download it would have yielded better comprehension of your comments in a fraction of the time.

Another point would be do a brief introduction to say that you are building a standalone html file that will demonstrate chart.js 4. You dive in a bit too quickly. I, as a Windows user, found it hard to know what tool you were using on your Mac. I am very used to seeing tutorials use VSCode and instead you are using some kind of Mac text editor which looks almost the same.

The idea is to teach quickly and efficiently, and cover both Windows and Mac users, or if you are just caring about Mac developers, state that up front.

Thanks for listening and thanks for creating content to help devs learn chartjs 4.
