DocRaptor HTML TO PDF API

How to create a PDF with a Highcharts Chart

Highcharts is one of the most popular charting libraries and is used in many DocRaptor PDFs. This tutorial walks through creating a PDF with a Highcharts pie chart. These same steps also apply to line charts, bubble charts, donut charts, or any other chart type—and even other charting libraries.

Enable JavaScript

First, enable JavaScript in the DocRaptor API by setting the javascript parameter to true. You can see this parameter defined in any of the complete code examples below the tutorial. DocRaptor disables JavaScript by default to speed up the generation time of documents that don't use JavaScript.

Disable Animation

Many charting library examples include animation by default because it looks impressive, but animation isn't supported by DocRaptor (or PDFs in general). Make sure animation is disabled in your chart; otherwise we may render your document before the chart has completed the animation

Write the HTML and CSS

Let's start by including the Highcharts JavaScript library:

<script src="https://code.highcharts.com/highcharts.js"></script>

Optionally. change the document layout to landscape and remove the default margin to make it a full bleed document (where the content goes to the edges of the document):

@page {
  size: landscape;
  margin: 0;
}

Most chart libraries, including Highcharts, require the chart's containing element to have an explicit height and width. As we're trying to make a full bleed document, we'll simply define the height and width as the size of DocRaptor's default document size, US-Letter:

<div id="container" style="height: 816px; width: 1056px;"></div>

Create the Chart

To make the actual chart, we'll use the Pie Chart Demo code straight from the Highcharts website:

<script>
  Highcharts.chart('container', {
      chart: {
          plotBackgroundColor: null,
          plotBorderWidth: null,
          plotShadow: false,
          type: 'pie'
      },
      title: {
          text: 'Browser market shares January, 2015 to May, 2015'
      },
      tooltip: {
          pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
      },
      plotOptions: {
          pie: {
              allowPointSelect: true,
              cursor: 'pointer',
              dataLabels: {
                  enabled: false
              },
              showInLegend: true
          }
      },
      series: [{
          name: 'Brands',
          colorByPoint: true,
          data: [{
              name: 'Microsoft Internet Explorer',
              y: 56.33
          }, {
              name: 'Chrome',
              y: 24.03,
              sliced: true,
              selected: true
          }, {
              name: 'Firefox',
              y: 10.38
          }, {
              name: 'Safari',
              y: 4.77
          }, {
              name: 'Opera',
              y: 0.91
          }, {
              name: 'Proprietary or Undetectable',
              y: 0.2
          }]
      }]
  });
</script>

Wait for JavaScript to Finish

Unlike a traditional browser, which is constantly running JavaScript, our PDF renderer must detect when the JavaScript is "finished." Unfortunately, it isn't easy to programmatically detect when charts finish rendering, especially charts with external/AJAX-based data sources.

We recommend using our docraptorJavaScriptFinished() JavaScript function to explictly tell us when your chart library is finished. When the function returns true, we'll generate your PDF. For the fastest rendering, you should detect the rendering of the chart element. For simplicity, we'll just wait a couple seconds before making this PDF, which is plenty of time for Highcharts to finish:

<script>
  var didWait = false;
  docraptorJavaScriptFinished = function() {
    if (! didWait) {
      setTimeout(function(){
        didWait = true;
      }, 2000);
      return false;
    }
    return true;
  }
</script>

See any of the below complete code samples to generate a Highcharts Pie Chart PDF in your programming language with DocRaptor's HTML-to-PDF API.

Select Your Language

Using DocRaptor's API

Below are the basics of using DocRaptor's HTTP API. It can easily be used in any programming language, but if we don't have a native agent for your language, please let us know! That'll help us write the best examples and agents.

The API key shown here, YOUR_API_KEY_HERE, actually works! Use it for testing without creating an account. The only requirement is test mode must be used (test parameter set to true).

To make documents, send a POST request to this URL:

https://YOUR_API_KEY_HERE@staging-api.docraptor.com/docs

Send JSON-encoded API parameters (you'll need to set an HTTP header for Content-Type as application/json). These are the only required parameters:

{
  "type": "pdf",
  "document_content": "Hello World!"
}

Generating the Document with cURL

Here's a completely functional code sample for this tutorial:

cat <<-'DOCUMENT_OPTIONS' > docraptor_parameters.json
  {
    "test": true,
    "document_type": "pdf",
    "document_content": "<script src=\"https://code.highcharts.com/highcharts.js\"></script><div id=\"container\" style=\"height: 816px; width: 1056px;\"></div><script>Highcharts.chart('container', {chart: {plotBackgroundColor: null,plotBorderWidth: null,plotShadow: false,type: 'pie'},title: {text: 'Browser market shares January, 2015 to May, 2015'},tooltip: {pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'},plotOptions: {pie: {allowPointSelect: true,cursor: 'pointer',dataLabels: {enabled: false},showInLegend: true}},series: [{name: 'Brands',colorByPoint: true,data: [{name: 'Microsoft Internet Explorer',y: 56.33}, {name: 'Chrome',y: 24.03,sliced: true,selected: true}, {name: 'Firefox',y: 10.38}, {name: 'Safari',y: 4.77}, {name: 'Opera',y: 0.91}, {name: 'Proprietary or Undetectable',y: 0.2}]}],accessibility: {enabled: false}});var didWait = false;docraptorJavaScriptFinished = function() {if (! didWait) {setTimeout(function(){didWait = true;}, 2000);return false;}return true;}</script><style>@page {size: landscape;margin: 0;}</style>",
    "javascript": true
  }
DOCUMENT_OPTIONS

The DocRaptor JavaScript Library

The DocRaptor JavaScript library makes it easy to create PDFs with JavaScript. The library does not require jQuery, but you can use jQuery to define your document content. When a PDF is requested, the library constructs a hidden form and submits it to the DocRaptor API. The form is necessary to trigger the browser download window.

This library exposes your API key in your website source code. This code should never be used in a publicly-accessible location, instead try using our referrer-based API or a server-side agent such as PHP or Ruby.

JavaScript Example

<html>
  <head>
    <script src="https://docraptor.com/docraptor-1.0.0.js"></script>
    <script>
      var downloadDocumentFrom = function(selector) {
        // this key works in test mode!
        DocRaptor.createAndDownloadDoc("YOUR_API_KEY_HERE", {
          name: "highcharts-chart",
          test: true, // test documents are free but watermarked
          document_type: "pdf",
          document_content: document.querySelector(selector).innerHTML,
          // document_url: "https://docraptor.com/examples/invoice.html",
          javascript: true
          // prince_options: {
          //   media: "print", // @media 'screen' or 'print' CSS
          //   baseurl: "https://yoursite.com", // the base URL for any relative URLs
