Overview of this book

Highcharts is a JavaScript library that enables web developers to create a wide range of different, highly customized charts. Highcharts easily integrates with existing JavaScript frameworks and is simple enough to make a column chart in a few lines of code, but flexible enough to handle more complex charting scenarios such as viewing multiple chart types with different data sources on a multitude of devices and form-factors. "Highcharts Cookbook" is a practical guide that provides you with clear, step-by-step recipes to create dynamic, functional charts in your web applications using Highcharts. With "Highcharts Cookbook", you will create and design dynamic and versatile charts in different scenarios. "Highcharts Cookbook" through its wide array of recipes will walk you through everything you need to know about Highcharts and will enable you to unleash its full potential in your web applications quickly and easily. You will learn how to integrate Highcharts with different frontend and backend libraries such as ExtJS, jQuery, and the Yii framework with some examples in Python, PHP, and NodeJS. You will also cover how to handle user interactions like form input and mouse events, how to fetch remote data in CSV, XML, and JSON format, and how to render charts for offline usage.

Updating a chart on the backend

Until this point, we've mostly been getting data from some source. We never modify or change data at the source. This recipe will briefly go through the details of how we might send data to some server that affects our chart.

Getting ready

To set up a basic page and install jQuery and Highcharts, refer to the Getting ready section of the Creating your first chart recipe in Chapter 1, Getting Started with Highcharts. For our example, assume that the JSON we retrieve looks like the following code:

{'y': 0}

How to do it...

To get started, perform the following steps:

Create a textbox and a button on our page as follows:

<div id='container'></div><br/>
<input type='text' id='new_value' />
<input type='submit' id='replace_value' value="Replace value"/>

Create a handler for the instance when the button is pressed, as shown in the following code:

$('#replace_value'').on('click', function(event) {
  var newValue = $('#new_value').val();
    ...
