Polar chart with Chart JS

========================================================================

In this course you will learn how to create a polar chart from scratch! The web is changing and new skills are in huge demand! One of these skills is data visualization for the web. How good are you in visualizing data into chart on the web?

Many people prefer the easy road. Just make it in Excel and post the picture on the web. Very easy but not very beneficial nor professional. Companies are realizing that websites is one of the best places to share data and to create dashboards.

Because of this, companies need skillful chart makers for the web! This skill will keep on growing and is in huge demand! In this course you will learn how to create your own polar chart with one of the best JavaScript library named Chart JS.

This course teaches you in a very easy bite size manner. You will start making a chart in minutes just by following along with every video. Each video handles one line of coding at the time. This means you really can follow this course very easy and you cannot make a mistake. You cannot fail with this if you follow the video.

You will also understand the background and meaning of the codes. Learning how to code is just like learning a language. You need to know first the meaning of the words. Once you understand it you will be able to create your own charts. I explain every piece of code we use! So at the end you can fluently create a polar chart.

========================================================================

How structured is this course?

========================================================================

This course works with the spoon feeding method. This basically means you will handle one piece of code everytime. Starting to code can be hard if we instantly handle 10 piece of code at once. The best way to learn is with baby steps for, after walking and finally running!

This course makes sure you know what to do and how to do it and why you do it. Once you learned the skill you will notice that create charts is really easy.

========================================================================

========================================================================

Why take this course?

========================================================================

The biggest question you might have is this. This course teaches you how you can create a Polar chart with Chart JS. Video is the best way to learn because you can follow along and understand it. Finally, the real value of this is that many companies are paying data visualizers a huge salary. Why??

Data visualizers have the ability to translate Big Data into a chart. This wonderful talent is a real time saver. With Big Data we experience an extreme overdose of data overload. The best medicine for this overdose is the use of charts! Charts save time and can translate data that takes hours to read into consuming it in only seconds! Charts is a super weapon! Learning this skill means real values for a company and an increase pay raise! So do not learn this skill for me but for you and get that pay raise!

Polar Chart JS: Download the files

In this lecture you will prepare with the right documents. Chart Js has a special JavaScript file that you need to download. You can download one of the two files:

  • Chart.js file
  • Chart.min.js file (minimized version, available in the resource section in a ZIP-file)

For this course I will be using the minimized version. It is fully optimized for speed and requires the least amount of kb to download. This is important if your future readers want to see your chart. It always needs to be quick.

In the resource section I placed a downloadable minimized version. However, I do understand that perhaps you want to download the latest version. In that case visit the official list. Link is included in the resource section.

Data Analyst, Market Researcher, Data Visualizer!

Nicky Wong is an expert in translating data into market opportunities. Data is his passion, Excel, Databases and Big Data are truly wonderful topics. As an absolute data lover and he is always looking for ways to analyze it. It started with stock market facts and now quickly turned to everything that is unique and different.

However, all the information have one primairy goal and that is "How to use this information to gain a competitive advantage". As a Market Researcher with it roots in Marketing Nicky understands that knowledge is power. Whatever you do make sure you use data at your advantage.

My vision of Data and the future

=====================================================================

Why Data visualization matters!

I truly belief that Big Data is giving us all a new obstacle to overcome! Information overload is a serious challenge and with Big Data it only multiplies the issue. If you are a data miner you will know that much data has no meaning if you cannot connect any meaningful dots.

Large chunks of data, reports and tables are not effective. It is impressive to get a huge database but it is demotivating for others to read data. The biggest data trend is increasing this issue! Big Data = Information Overload x 10.

From (Digital) Information Age to the (Digital) Understanding Age

A data analyst can analyze data but the most important skill is Data Visualization! These so called "data visualizers" will develop a new skill gathering meaningful information and present it in a very understandable and effective way.

The issue is not anymore the data but the way to give meaning and communicating meaning to others. The person who can do that will have a huge advantage in the so ever growing Big Data world.

Big Data is here! Data Visualizer is on it`s way! In all of my courses I use techniques to create understandable data and present it in an impactful manner.
