[Simple Trick]-Stacked and Grouped Bar Chart Chart.js Example

In This article, we will discuss how to Create grouped and stacked charts in Chart.js. First, let you know that it is possible to create a grouped and stacked chart in Chart js.

Stacked and Grouped Bar Chart Chart.js Example

The StackGroupbarChart is the variable that contains all the datasets and StackGroupbarChartOptions variable contains all the styling properties of the Stack Group barChart.

StackGroupbarChartOptions is an object with multiple properties used that would be required to display our data in the form of a Bar chart.

The labels property in StackGroupbarChart variable is an array that is used to assign the names to each bar, chart and the datasets property is also an array that contains information such as label title, bar backgroundColor, bar borderColor, borderWidth data.

Code Explanation

As you can see in the above code we have three sets of data and each set has a number of developers belonging to a particular technology i. e App Developer, Andriod Developer, C# Developer, and Java Developer. now we want to create a ‘stack’ chart these using App Developer and Andriod Developer datasets and a ‘group’ bar chart using C# Developer and Java Developer dataset.

Now what’s awesome about this is that this is HTML, this is responsive, it’s using canvas. There are eight different chart types and it’s totally open source. So I can’t imagine a reason why you wouldn’t want to use this project over some other charting solutions. Now there are things like D3, D3is an amazing package in the ecosystem. However, D3 is going to be overkill if you need a simple chart like one of these.

And these charts aren’t even that simple, to be honest. if you need a chart, you know, learning D3 is great. But if you need advanced visualizations, then D3 is probably going to be more up your alley. But if you’re just doing beautiful charts, check out chart js.

It’s awesome. Okay, so let’s head to documentation here. And as you can see, we have some pretty sweet docs. We have a line chart bar chart. And if you select the heading of any of these, it gives you not only just like an example, but a working example.

Now we also have pie and donut charts.Now a doughnut chart is just a sort of hipper way of showing a pie chart at this point it’s showing the exact same data but you see these used all over the place like uses them and stuff like that and here we have scales which allows you to fully scale data whether it’s things like logarithmically and stuff like that.

But as you can see here, these are some of the best docs around so you can head to docs and just head in here and just see what’s available get inspired and in the next video we’re going to create our very first line chart right up top here and I’m going to talk a little bit about Chart JS while we go along so the other charts are a little easier once we get into them. Cool. So this is Chart JS. Hope you’re excited, we’re going to be building some really cool stuff.
