# Chart.js — Time Axis

Chart.js — Time Axis. In this article, we’ll look at how to create charts with Chart.js. Step Size. We can change the step size of the linear axis. Time Cartesian Axis. Time Cartesian axis is used to display times and dates. To add the time and number data with the t and y properties. We can make creating charts on a web page easy with Chart.js.

In this article, we’ll look at how to create charts with Chart.js.

## Step Size

We can change the step size of the linear axis.

For example, we can write:

``````var ctx = document.getElementById('myChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'line',
data: {
datasets: [{
label: 'First dataset',
data: [0, 0.5, 1, 1.5, 2]
}],
labels: ['January', 'February', 'March', 'April']
},
options: {
scales: {
yAxes: [{
ticks: {
max: 5,
min: 0,
stepSize: 0.5
}
}]
}
}
});``````

We change the `stepSize` to 0.5 so that the ticks are in intervals of 0.5.

## JavaScript: Chessboard Program

Exercise from Eloquent JavaScript. Today, we will write a function that forms a chessboard. You can find the exercise in the Eloquent Javascript book (3rd edition, chapter 2; Program Structure). Write a program that creates a string that represents an 8×8 grid, using newline characters to separate lines. At each position of the grid there is either a space or a “#” character. The characters should form a chessboard.

## Learning JavaScript: Development Environments for JavaScript Programming

One of the nice things about learning JavaScript these days is that there is a plethora of choices for writing and running JavaScript code. In this article, I’m going to describe a few of these environments and show you the environment I’ll be using in this series of articles.

## Learning JavaScript: Data Types and Variables

To paraphrase the title of an old computer science textbook, “Algorithms + Data = Programs.” The first step in learning a programming language such as JavaScript is to learn what types of data the language can work with. The second step is to learn how to store that data in variables. In this article I’ll discuss the different types of data you can work with in a JavaScript program and how to create and use variables to store and manipulate that data.
