How to use Data Structures For Multiple Datasets in Chart js

How to use Data Structures For Multiple Datasets in Chart js

In this video we will cover how to use data structures for multiple datasets in chart js. Data structures are very powerful and with it we can create multiple datasets from a single data structure and display them at once.

This creates a very nice concise code without too much excess code. We will create 3 independent lines which are all stored in a single data structure. Giving them their own colors and extracting the specific values from the data 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.

Hi. How to add another lines for Food Sales, Drink Sales & Cake Sales for other stores for comparison in the same chart. For example, 3 different shop. So in chart you will have 3 red lines for Food Sales, 3 blue lines for Drinks Sales & 3 green lines for Cake Sales. Can this be done?

Hi! and greetings from Argentina. I'm trying to open a modal, to list some projects from every chart in a crm dashboard. I did it with basic bar chart, and doughnut chart, but can't make it work with stacked. For some reason, can't parse the data. If you have the chance, could you make a quick video for this? Thanks!!!

[oludedavid]

Thank you for this video, what if we have not just sales but cost, profit etc how u go about that

[juanpablodossantos]

Hey your video was really helpful :), I just want to ask, can I actualize "sales Number" constant in runtime and force the chart to "actualize" ?

[TheIvanlisi]

I don't know how many datasets I will have.
Is it possible to make it in a for loop?
