▬ 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 3.9.1 ▬▬▬▬▬▬▬▬▬▬▬▬

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 3.9.1.

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.

For example we have 1 oct to 31 oct is there a way we can change it to 00:00 to 23:30. Please and please your response and help is very important to me. Thanks.

is there away to stack tasks in one row?

[micaelaperez]

Hi, I need to replace the data values of the datasets with two variables that contain, one the start dates and the other the end dates of the tasks. Could you tell me how to do it. Thank you so much

[KlausEisert]

a very helpfull tutorial. I created my gantt chart like your example. It was a bit tricky to build the today line. The plugin "todayline" was not working by declaration in the "plugins" area. But this was working:
Chart.register(todayLine);
I have also watched the draggable video. Unfortunately this is not working together with this gantt example. Has anybody a running solution?

[ajayjoseph]

Can you create drag-and-drop task lists or click and expand dynamically instead of hardcoding them?

[BenjaminJannedy]

I it possible to share the code for the Gantt Chart, somehow? It would be easier to understand if I could read the code in my editor!

[aussieexplorer]

Can this be done in latest version of chartjs - 4.4.6?

[peaichunong]

Nice tutorial, may I know if react-chart-js2 can do the same for the gantt chart too?

[andreamira]

Hola una pregunta se puede poner oct - 2022 nov - 2022 y eso no se puede hacer como en una tabla

[fauxcompte-fzzo]

Is what you're doing achievable just with the Chart JS doc?
What I'm wondering is whether we can get all the info about ctx.moveTo, x.getPixelForValue, etc in the documentation. Because I can't find them.

[mohammadabdulamer]

How do i get the full finished code
I need to do a gantt chart for angular 15 & cant seem to find any free good library can you suggest any?

[aniketdhamal]

Question: When using it with typescript, I want to mention the type of data variable, which I found ChartData but ChartData is generic and giving error "Generic type ChartData requires 1 type argument(s)" and there is child class

[amihaiatias]

great series idea!!
how about multiple tasks on each name? ( multiple dates span on 1 line)

[ravikiran.vempati]

[johnervinmanimtim]
