The most modern Pie Chart component

In the last tip a show you how to build The most modern Carousel component using CSS Scroll Snap. This time we’ll follow the same line to build a Pie Chart!

But before starting, just wanted to mention that if you’re a Packt user, this week my book on Testing Vue.js components with Jest has been published there too!

Back to the topic, this time I’m showing you another new CSS feature: Conic Gradient.

With it, we can easily build a Pie Chart component. In fact, it’d be very easy to build a color palette component, but that’s another topic!

In order to construct a pie chart, we need to define every section of the conic gradient, which is used on the background css property.

For instance, the following pie chart:

Is defined with the following CSS rule:

background: conic-gradient( 
  #00A37A 0 40%,
  #365164 0 70%,
  #A54f93 0 100% 

As you see, in each section you must define the color, the position from the center (in this case always 0) and how much angle that section must take.

The angle of that section must be absolute: they act like different layers that overlap each other in a Z index. However you probably want to pass to the Pie Chart component the “piece” of the cake that a section must take. Something like:

  pieData: [
    { color: "#00A37A", value: 40 },
    { color: "#365164", value: 30 },
    { color: "#a54f93", value: 30 }

So that when you sum up all pieData values, they total 100.

Given this introduction, let’s build a PieChart.vue component. This component must take the above pieData structure and build the right background: conic-gradient(...) given that data:

  <div class="pie-chart" :style="pieStyles"></div>

export default {
  props: ["pieData"],
  computed: {
    pieStyles() {
      let acum = 0;
      let styles =
        segment => `${segment.color} 0 ${(acum += segment.value)}%`

      return {
        background: `conic-gradient( ${styles.join(",")} )`

<style scoped>
.pie-chart {
  border-radius: 50%;

First, notice we gave it a 50% border-radius in order to make it rounded.

The main part of this component is in the pieStyles computed prop. Basically there we map the pieData property to build an array of conic sections with the shape of "#aeaeae 0 30%" for instance, and finally build it in the background CSS property.

In that way, for the following data:

  pieData: [
    { color: "#00A37A", value: 40 },
    { color: "#365164", value: 30 },
    { color: "#a54f93", value: 30 }

Visualizing data with NGX-Charts in Angular

Data Science, Data Analytics, Big Data, these are the buzz words of today’s world. A huge amount of data is being generated and analyzed every day. So communicating the insights from that data becomes crucial. Charts help visualize the data and communicate the result of the analysis with charts, it becomes easy to understand the data.

There are a lot of libraries for angular that can be used to build charts. In this blog, we will look at one such library, NGX-Charts. We will see how to use it in angular and how to build data visualizations.

What we will cover:

  1. Installing ngx-chart.

  2. Building a vertical bar graph.

  3. Building a pie chart.

  4. Building an advanced pie chart.

A brief introduction about NGX-Charts

NGX-Chart charting framework for angular2+. It’s open-source and maintained by Swimlane.

NGX-Charts does not merely wrap d3, nor any other chart engine for that matter. It is using Angular to render and animate the SVG elements with all of its binding and speed goodness and uses d3 for the excellent math functions, scales, axis and shape generators, etc. By having Angular do all of the renderings it opens us up to endless possibilities the Angular platform provides such as AoT, Universal, etc.

NGX-Charts supports various chart types like bar charts, line charts, area charts, pie charts, bubble charts, doughnut charts, gauge charts, heatmap, treemap, and number cards.

Installation and Setup

1. Install the ngx-chart package in your angular app.

npm install @swimlane/ngx-charts --save

2. At the time of installing or when you serve your application is you get an error:

ERROR in The target entry-point "@swimlane/ngx-charts" has missing dependencies: - @angular/cdk/portal

You also need to install angular/cdk

npm install @angular/cdk --save

3. Import NgxChartsModule from ‘ngx-charts’ in AppModule

4. NgxChartModule also requires BrowserAnimationModule. Import is inAppModule.


import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { NgxChartsModule }from '@swimlane/ngx-charts';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
  declarations: [
  imports: [
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }

Amazing! Now we can start using ngx-chart component and build the graph we want.

In the AppComponent we will provide data that the chart will represent. It’s a sample data for vehicles on the road survey.
