How to use timescales and how to enter dates and time in Chart JS

How to make a timescale in chart JS? In this video we will explore how to use timescales and how to enter dates and time in Chart JS. Timescale Axis or timescales is a part of the ChartJS documentation that is truly lacking so the question is very understandable. The timescales is a part of the timescale cartesian and what we want to do here is adjust the X-axis with a timescale.

To answer the question of how to make a timescale in chart JS we need to know a few things. First of all we need to add a chartjs date adapter library. Common one will be the data-fns or Luxon. Avoid using Moments.js as that one is deprecated. Which means they do not maintain nor update the library anymore.

We will also check and look at the difference between the type timeseries and time. And use in chart.js time parser example. Which speeds up drawing the chart with chart.js timestamps.

Let's explore how to do this.

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.

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 Youtube 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.
