Why did I created these Chart JS video tutorials?
Have you ever used Excel where charts appear almost magically with a click on a button. You notice if you look at a chart or graph you can absorb information within seconds which would take you minutes if it is a table with data.
"A picture is worth a thousand words"
We all know that pictures and colors spark the mind. However, if you try to draw or code a 📊 bar chart or a 📈 line chart, or any type of chart in a Javascript library it is a big challenge. The documentation makes it hard and the it is very hard to work with a canvas tag.
Ancient Egypt used hieroglyphs in their writing system. Which was both logical and creative at the same time. And this is why I love charts as well. A chart is the closes to translating logic into visuals. Making the chart interactive is the best way to communicate your message to others.
If we know about this why is coding charts so complicated?
Because computer programming language is based on 100% logic. This is why when you look at Chart.JS, D3.JS, Chartist and other chart libraries in JS you will need to basically explain in logic to a computer what to make visual.
How and where can I help?
My goal and focus is on creating easy to understand Chart.JS videos so you can start using Chart JS in all your website endeavors making Chart.JS a topnotch and leading JS library for the years to come. Just like any programming library once more people use Chart JS it will attract more people to contribute and grow. The videos on RU-vid and my complete course on Udemy are here to give a helping hand.
Seeing Chart.JS evolve from Chart.JS 1.0 to Chart.JS 3.0 and with their currently new expansion to Chart.JS 3.0 we can expect more new exciting charts in the near future.
About Chart.JS 3 | Chart JS 3
Chart JS is one of the most use Javascript libraries for the drawing charts. It is designed to create charts in the canvas tag which is great but at the same time slightly challenging for most people. However, knowing how to draw a chart will give you a big edge and most dashboards are consistently adding charts along data tables. Chart JS makes your data more alive and visually more appealing.
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 your tutorial here. How to change the size and shape of the button?
@spydergs07
@spydergs07 2 года назад
You can use the style method in javascript to change the size and shape of your css is setup with classes for the shapes. document.querySelector('.square').className ='circle'; If you have css classes setup for the shapes you want.

This explanation was very well explained. I liked how you went step-by-step on what the value does, what JavaScript does, everything. I have been wondering for awhile why choose this or that "querySelector" why a period here and all of that. You answered everything perfectly and I have a greater understanding of why to choose that. Thank you!
@Humannacle
@Humannacle Год назад
Yeah well explained, thank you so much but I got a question, what if we have 3 buttons (1st button is the main heading text, 2nd is 2nd heading text and 3th is 3th heading text) so what if we click on 2nd button and it changes our main heading text to 2nd and after that if we want to go back to main heading text what command do we use? function doSomething(){ document.selectElementById("Our main heading text's Id").innerHTML = "2nd heading text's name"; } function changeText(){ ("Our 2nd heading text's name" = document.selectElementById("Our main heading text's Id").innerHTML; } Smth like this or am I wrong?

@ChartJS-tutorials 2 года назад
Thank you for your question. I have created an answer video regarding to your question about querySelectAll here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Aryaf8xz1DI.html This video will show you exactly how it works and why it is quite different from the basic querySelector. Your second question will be made in a different video as that is a more complicated matter.

If has any solution please provide as soon as possible
@ChartJS-tutorials
@ChartJS-tutorials Год назад
@@editingtuto1.011 you have 2 options. Which option you select would depend on how that button would be connected. 1. You either go and use a database because that changed value should always display from now on. 2. You use can use the localStorage. For example with a shopping cart this is oftenly done see this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2BY2oV2AMuI.html Where it only shows the value storage on the computer instead of database just like a cookie. If they remove the cookie the item would be removed from the shopping cart.

Hi Shevonne, do you know how to check for errors in the developer tab in Chrome browser? For Mac use OPTION + COMMAND + i For Windows F12 One you open it click on the >> button to select "console". The console will show you error if your button has any incorrect JS. That is a very useful tool for debugging and solving your JS errors. Errors will be stated in red with the exact line of code where it failed to load. Check that line and explore what the error might be.
