How to Convert Arrays into Data Structures in Chart js

How to Convert Arrays into Data Structures in Chart js

In this video we will cover how to convert arrays into data structures in chart js. Data structures are basically multi dimensional arrays. However, when you extract your arrays from your database you tend to have multiple arrays. Figuring out how to join them into a nice data structure can be challenging.

In this video we break it down in an easy to follow step by step process. Where we have 5 individual arrays that need to be combined into a nice data structure with the proper names and structure.

Let's explore this right now!

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.

How would I dynamically create multiple datasets for the same day on a bar chart using a single array of objects that would be dynamically generated. For instance my array would be:
[
{ day: '4/13/2023', name: 1, count: 1 },
{ day: '4/13/2023', name: 1, count: 2 },
{ day: '4/13/2023', name: 1, count: 5 },
{ day: '4/14/2023', name: 2, count: 3 },
{ day: '4/14/2023', name: 2, count: 1 },
{ day: '4/14/2023', name: 2, count: 4 }
]
I would like to show Stage name 1 and stage name 2 both for '4/13/2023' with their count, etc.?
