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.

app.module.ts

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';
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    NgxChartsModule
  ],
  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.

Visualization with Plotly.Express: Comprehensive guide

I frequently come up with an ideal visualization and then struggle to code it. It would be to the point, expressive, and easy to interpret, but it’s impossible to create. When I found Plotly it made plotting, well, much easier.

Plotly.Express, first introduced in version 4.0.0 is a high-level abstraction to Plotly API optimized to work perfectly with data frames. It’s very good, though not flawless. I see the biggest gap in the number of examples or links to the API documentation. That’s why I have decided to use my experience with the library to write a guide.

To run the chart and exercises, please use the Plotly Express — Comprehensive Guide.ipynb notebook on Github. All the code in this article is in python.

Table of contents:

Installing Plotly Express

Plotly.Express is a regular part of the Plotly python package, so the easiest is to install it all.

## pip 
pip install plotly

## anaconda
conda install -c anaconda plotly

Plotly Express also requires pandas to be installed, otherwise, you will get this error when you try to import it.

[In]: import plotly.express as px
[Out]: ImportError: Plotly express requires pandas to be installed.

There are additional requirements if you want to use the plotly in Jupyter notebooks. For Jupyter Lab you need jupyterlab-plotly. In a regular notebook, I had to install nbformat (conda install -c anaconda nbformat)
