# Convert highcharts.js into an image

Generate charts and graphs using Highcharts.js

You can generate images of charts using Highcharts.js + the HTML/CSS to Image API.  When making charts, be sure to disable any animations. They may cause issues when creating the image.

This is a working HTML/CSS to Image API example that produces an image.
The rendered output, source, and non-content request parameters below show the parts needed to reproduce or adapt it.

## Rendered image and interactive editor

- [Open the rendered image](<https://hcti.io/v1/image/01a029cc-7a85-775b-8150-1bcb17da4a22>)
- [Open the interactive example](https://htmlcsstoimage.com/examples/convert-highchart-js-to-image/php)

## HTML

```html
<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/series-label.js"></script>

<div id="container"></div>

<script>  
Highcharts.chart('container', {
  chart: {
    animation: false
  },
  title: {
    text: 'Solar Employment Growth by Sector, 2010-2016'
  },

  subtitle: {
    text: 'Source: thesolarfoundation.com'
  },

  yAxis: {

    title: {
      text: 'Number of Employees'
    }
  },
  legend: {
    layout: 'vertical',
    align: 'right',
    verticalAlign: 'middle'
  },

  plotOptions: {
    series: {
      animation: false,
      label: {
        connectorAllowed: false
      },
      pointStart: 2010
    }
  },

  series: [{
    name: 'Installation',
    data: [43934, 52503, 57177, 69658, 97031, 119931, 137133, 154175]
  }, {
    name: 'Manufacturing',
    data: [24916, 24064, 29742, 29851, 32490, 30282, 38121, 40434]
  }, {
    name: 'Sales & Distribution',
    data: [11744, 17722, 16005, 19771, 20185, 24377, 32147, 39387]
  }, {
    name: 'Project Development',
    data: [null, null, 7988, 12169, 15112, 22452, 34400, 34227]
  }, {
    name: 'Other',
    data: [12908, 5948, 8105, 11248, 8989, 11816, 18274, 18111]
  }],

  responsive: {
    rules: [{
      condition: {
        maxWidth: 500
      },
      chartOptions: {
        legend: {
          layout: 'horizontal',
          align: 'center',
          verticalAlign: 'bottom'
        }
      }
    }]
  }
});
</script>
```

## Request parameters

These are the additional non-content parameters used by the example. Combine them with the HTML and CSS above when constructing an API request.

```json
{
  "ms_delay": 200,
  "transparent_background": true
}
```

## Complete PHP request (cURL)

This is the complete PHP request for this example using cURL. It includes the HTML, CSS, authentication setup, API options, and response handling needed to reproduce the output.

```php
<?php

$request = [
    "html" => <<<'HCTI_HTML'
        <script src="https://code.highcharts.com/highcharts.js"></script>
        <script src="https://code.highcharts.com/modules/series-label.js"></script>
        
        <div id="container"></div>
        
        <script>  
        Highcharts.chart('container', {
          chart: {
            animation: false
          },
          title: {
            text: 'Solar Employment Growth by Sector, 2010-2016'
          },
        
          subtitle: {
