How to Convert Arrays into Multi Dimensional Arrays or Data Structures in Chart js

How to Convert Arrays into Multi Dimensional Arrays or Data Structures in Chart js

In this video we will cover how to convert arrays into multip dimensional arrays or data structures in chart js. I have very often said how powerful data structures are. However perhaps you have struggled to understand how to convert 2 or more arrays into a data structure or multi dimensional array. We will cover how to do that and how to draw our chart based on that specific item.

Understanding this will give you access to more advanced options. We will use using a scatter chart and convert the scatter chart into a line chart with the x and y coordinates. To do this correctly we must convert 2 arrays into one that is readible for the scatter chart in chart js.

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.

▬ Chart JS 3.6.0 ▬▬▬▬▬▬▬▬▬▬▬▬

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.

Thank you for the nice video. I am using database to populate dataset and labels. This given solution is good, but still not dynamic. Meaning If have more then 10 y arrays I will need to have the same number of dataset. Is it possible to have dynamic solution for multiple y arrays, without writing separate dataset for each of them.

Another nice video.. sir, could you show us how to flag one value as exception in chart JS.. let’s assume, I have a csv file with dynamic data and I have charted all the data.. now let’s assume out of the many values I want to colour code the highest, 2nd highest value as exceptions.. how do I do that..
flagged exceptions can either be displayed in different colour or flagged as data levels on. Thanks in advance
