In the age of big data and deep learning, data visualization is an extremely important tool for many applications.
In this episode, we're going to combine the Plotly JS library along with Angular and Firebase to create 3 different types of charts that are capable of handling real time data.
We'll start by building a basic 2 d line chart, and then we'll build up to a 3 d topographical chart.
Then we'll finish up with a ternary chart that's capable of staying in sync with the real time back end on Firebase.
The first step is to install the PlotlyJS library, which we can do with npm install plotly.js flag save.
Then add it to the script section in the angular dash CLI.json file.
It's worth noting that Plotly is a pretty big library.
So So if you wanna slim it down a little bit, go to your node modules and find just the script that you need for your app.
In this case, we're using the entire library, which is probably overkill for most situations.
Then in your typings dot d file, add the Plotly class so it's recognized by TypeScript.
Now we can start building our first line chart.
This chart will just be completely static just to show you the general concepts behind Plotly.
In the HTML, create an empty div, and then give it a template reference variable named chart.
Then in the component type script, we'll use view child as well as element ref.
Then we're going to build this chart service in the next step once we start using live data from Firebase, so you can ignore that for now.
And we'll also use the Lodash library.
So to get a hold of the div and the HTML, we use view child and then reference that chart variable that we name there.
Then we'll name it l in the TypeScript, which is more or less an Angular convention.
Then to actually build a Plotly chart, there are 3 basic variables that you need to be aware of.
First, we have element which is the HTML element that will be replaced by the chart.
And then we have data.
That's the actual data that's going to be displayed in the chart.
Here we have a few numbers on the x and y axis that will create a basic line chart with a curve.
The third variable is style, which defines the style options that vary from chart to chart.
And to put everything together, we just call plotly dot plot and pass it the element data and style.
Back in the app, we can see we get this simple line chart, but it's packed with a bunch of features from Plotly such as the ability to zoom in and zoom out.
You can save it as an image and do all kinds of different stuff to it.
So that was pretty simple.
Now let's build a 3 d chart that uses data from Firebase.
So I'm building a basic service here that injects the AngularFire database, then it returns the dataset we want as a Firebase list observable.
In this example, my database is a collection of arrays with each array having its own set of data points.
These data points correspond to the elevation of a mountain and I'll provide a link to the dataset in the description.
Now getting back to the component, we create a new function for this chart, but this time we pass it the data as an argument.
Like before we set the element variable, then we format the data specifically for 3 d charts.
So we pass the data as the z axis and set the type to surface.
Then for the layout or style, we set a few simple parameters here just to make the chart look And again, we call plotly dot plot and pass it these variables.
Now we need to pass the chart some data.
So we do this during n g on init by subscribing to the dataset in the database.
In this example, we don't expect our data to change.
So So we're just going to take 1 and then subscribe to it so we don't have a long running subscription, and then we'll pass the data from the subscription to the topo chart function.
Back in the app, you can see we get this really cool 3 d interactive chart based on our data in Firebase.
And there's a ton of ways you can customize this, so make sure to check out Plotly docs, and the community for more inspiration on what you can do.
So the last type of chart that we'll build is a chart that can to update its appearance based on real time data.
For this example, I have some user rankings that will rank a user based on their abilities as an analyst, designer, or developer.
And we're going to visualize this data on a ternary chart, which is basically just a triangle that compares 3 different types of data.
First, we're going to add a function to our service that will allow us to make this update in Firebase.
It just references a single data point and updates it with some new data.
Then in the component, we're going to subscribe to the data in ng on init.
But before we pass the data to the function, we're going to purge the chart existing in that element.
Then we'll go ahead and call the function that builds the chart.
But before we get there, let's create a function that will just randomize the data for a certain data point.
Then you can attach this function to a click event so the user can randomize the data just with a click of a button.
Now let's build this ternary chart.
We start by passing it the element as usual, then we map each of the 3 categories down to an array of its values.
In most cases, you'll need to map your data down to an array for it to work with any kind of data chart.
The rest of the code is mostly just presentational, so we just add a few options to give it with some nice looking styles.
Plotly has a big library of examples so you can usually find a good starting chart for most situations.
Now back in the app if we Click the button that says Realtime Update, we can see the red circle moving around the screen.
That's because it's actually being updated in the back end in Firebase.
That's it for real time charts with Plotly and Firebase.

In this video, the speaker discusses how to create a 2 d line chart using the Plotly JS library and Angular and discharged a 3 d top pages chart using the honor file. They explain the process of building a chart using the client's data and setting variables for the chart. The speaker also discusses the use of a graph to update its appearance based on real time data and explains how to use the Re v a update function to randomize data for a certain point.
Realtime Graphs and Charts with Plotly and Firebase
Learn how to connect realtime data to Plot.ly with the Firebase database and Angular 4 on the frontend. In this episode, I build three different graphs and charts designed to handle realtime data streams.
