# amCharts Export

Version: 1.2.2


## Description

This plugin adds export capabilities to all amCharts products - charts and maps.

It allows annotating and exporting chart or related data to various bitmap, 
vector, document or data formats, such as PNG, JPG, PDF, SVG, JSON, XLSX and 
many more.


## Important notice

Please note that due to security measures implemented in modern browsers, some 
or all export options might not work if the web page is loaded locally (via 
file:///) or contain images loaded from different host than the web page itself.


## Usage

### 1) Include the minified version of file of this plugin as well as the 
bundled CSS file. I.e.:

```
<script src="amcharts/plugins/export/export.min.js"></script>
<link  type="text/css" href="amcharts/plugins/export/export.css" rel="stylesheet">
```

Or if you'd rather use amCharts CDN:

```
<script src="//cdn.amcharts.com/lib/3/plugins/export/export.min.js"></script>
<link  type="text/css" href="//cdn.amcharts.com/lib/3/plugins/export/export.css" rel="stylesheet">
```

(this needs to go after all the other amCharts includes)

### 2) Enable `export` with default options:

```
AmCharts.makeChart( "chartdiv", {
  ...,
  "export": {
    "enabled": true
  }
} );
```

### ... OR set your own custom options:

```
AmCharts.makeChart( "chartdiv", {
  ...,
  "export": {
    "enabled": true,
    "menu": [ {
      "class": "export-main",
      "menu": [ {
        "label": "Download",
        "menu": [ "PNG", "JPG", "CSV" ]
      }, {
        "label": "Annotate",
        "action": "draw",
        "menu": [ {
          "class": "export-drawing",
          "menu": [ "PNG", "JPG" ]
        } ]
      } ]
    } ]
  }
} );
```


## Loading external libraries needed for operation of this plugin

The plugin relies on a number of different libraries, to export images, draw 
annotations or generate download files.

Those libraries need to be loaded for the plugin to work properly.

There are two ways to load them. Choose the one that is right:

### 1) Automatic (preferred)

All libraries required for plugin operation are included withing plugins */libs* 
subdirectory.

The plugin will automatically try to look in chart's [`path`](http://docs.amcharts.com/3/javascriptcharts/AmSerialChart#path) 
property. If your plugin files are located within plugins folder under amcharts 
(as is the case with the default distributions), you don't need to do anything -
the libraries will load on-demand.

If you are using relative url, note that it is relative to the web page you are 
displaying your chart on, not the export.js library.

In case you've moved the libs folder you need to tell the plugin where it is
`"libs": { "path": "../libs/" }`

### 2) Manual

You can also load all those JavaScript libraries by `<script>` tags. Since 
loading of libraries is on by default you will need to turn it off by setting 
`"libs": { "autoLoad": false }`

Here is a full list of the files that need to be loaded for each operation:

File | Located in | Required for
---- | ---------- | ------------
fabric.min.js | libs/fabric.js/ | Any export operation
FileSaver.js | libs/FileSaver.js/ | Used to offer download files
pdfmake.min.js | libs/pdfmake/ | Export to PDF format
vfs_fonts.js | libs/pdfmake/ | Export to PDF format
jszip.js | libs/jszip/ | Export to XLSX format
xlsx.js | libs/xlsx/ | Export to XLSX format


## Complete list of available export settings

-------- | ------- | -----------
backgroundColor | #FFFFFF | RGB code of the color for the background of the exported image
enabled | true | Enables or disables export functionality
divId | | ID or a reference to div object in case you want the menu in a separate container.
fabric | {} | Overwrites the default drawing settings (fabricJS library)
fallback | {} | Holds the messages to guide the user to copy the generated output; `false` will disable the fallback feature
fileName | amCharts | A file name to use for generated export files (an extension will be appended to it based on the export format)

fileListener | false | If true it observes the drag and drop feature and loads the dropped image file into the annotation
drawing | {} | Object which holds all possible settings for the annotation mode ([skip to chaper](#annotation-settings))


## Configuring export menu

Plugin includes a way to completely control what is displayed on export menu. 
You can set up menus, sub-menus, down to any level. You can even add custom 
items there that execute your arbitrary code on click. It's so configurable 
it makes us sick with power ;)

The top-level menu is configured via `menu` property under `export`. It should 
always be an array, even if you have a single item in it.

The array items could be either objects or format codes. Objects will allow you 
to specify labels, action, icon, child items and even custom code to be executed
on click.

Simple format codes will assume you need an export to that format.

### Simple menu setup

Here's a sample of the simple menu setup that allows export to PNG, JPG and CSV:

```
"export": {
  "enabled": true,
  "menu": [ {
    "class": "export-main",
    "menu": [ "PNG", "JPG", "CSV" ]
  } ]
}
```

The above will display a menu out of three options when you hover on export 
icon:

* PNG
* JPG
* CSV

When clicked the plugin will trigger export to a respective format.

If that is all you need, you're all set.

Please note that we have wrapped out menu into another menu item, so that only 
the icon is displayed until we roll over the icon. This means that technically
we have a two-level hierarchical menu.

If we opmitted that first step, the chart would simply display a format list 
right there on the chart.

### Advanced menu setup

However, you can do so much more with the menu.

Let's add more formats and organize image and data formats into separate 
submenus.

To add a submenu to a menu item, simply add a `menu` array as its own property:

```
"export": {
  "enabled": true,
  "menu": [ {
    "class": "export-main",
    "menu": [ {
      "label": "Download as image",
      "menu": [ "PNG", "JPG", "SVG" ]
    }, {
      "label": "Download data",
      "menu": [ "CSV", "XLSX" ]
    } ]
  } ]
}
```

Now we have a hierarchical menu with the following topology:

* Download as image
  * PNG
  * JPG
  * SVG
* Download data
  * CSV
  * XLSX

We can mix "string" and "object" formats the way we see fit, i.e.:

```
"export": {
  "menu": [
    "PNG", 
    { "label": "JPEG",
      "format": "JPG" },
    "SVG"
  ]
}
```

The magic does not end here, though.

### Adding custom click events to menu items

Just like we set `label` and `format` properties for menu item, we can set 
`click` as well.

This needs to be a function reference. I.e.:

```
"export": {
  "menu": [
    "PNG", 
    { "label": "JPEG",
      "click": function () {
        alert( "Clicked JPEG. Wow cool!" );
      } },
    "SVG"
  ]
}
```

### Adding external legend

In case you have an external legend you need to define the position where it should get placed in your export.
By default it obtains the dimensions from the container but you can optionally overwrite those settings as shown below.

```
"export": {
  "legend": {
    "position": "top",  // or "right", "bottom" and "left" are possible
    "width": 200,       // optional
    "height": 200       // optional
  }
}
```

### Menu item reviver

By passing the `menuReviver` callback function you can modify the resulting menu 
item or relative container, before it gets appended to the list (`ul`). The 
function takes two arguments and it needs to return a valid DOM element.

```
"export": {
  "menuReviver": function(item,li) {
    li.setAttribute("class","something special");
    return li;
  }
}
```

### Menu walker

In case you don't like our structure, go ahead and write your own recursive 
function to create the menu by the given list configured through `menu`.

```
"export": {
  "menuWalker": function(list,container) {
    // some magic to generate the nested lists using the given list
  }
}
```

### Printing the chart

Adding menu item to print the chart or map is as easy as adding export ones. You 
just use "PRINT" as `format`. I.e.:

```
"export": {
  "menu": [
    "PNG", 
    "SVG",
    "PRINT"
  ]
}
```

Or if you want to change the label:

```
"export": {
  "menu": [
    "PNG", 
    "SVG",
    {
      "format": "PRINT",
      "label": "Print Chart"
    }
  ]
}
```

### Annotating the chart before export

OK, this one is so cool, you'll need a class 700 insulation jacket.

By default each menu item triggers some kind of export. You can trigger an 
"annotation" mode instead by including `"action": "draw"` instead.

```
"export": {
  "menu": [ {
    "class": "export-main",
    "menu": [ {
      "label": "Download",
      "menu": [ "PNG", "JPG", "CSV", "XLSX" ]
    }, {
      "label": "Annotate",
      "action": "draw"
    } ]
  } ]
}
```

Now, when you click on the "Annotate" item in the menu, the chart will turn into 
an image editor which you can actual draw on and the menu gets replaced by the 
default annotation menu.

If you don't like the detault annotation menu, you can define your own:

```
"export": {
  "menu": [ {
    "class": "export-main",
    "menu": [ {
      "label": "Download",
      "menu": [ "PNG", "JPG", "CSV", "XLSX" ]
    }, {
      "label": "Annotate",
      "action": "draw",
      "menu": [ {
        "class": "export-drawing",
        "menu": [ "JPG", "PNG", "SVG", "PDF" ]
      } ]
    } ]
  } ]
}
```

Now, when you turn on the annotation mode, your own submenu will display, 
allowing to export the image into either PNG, JPG, SVG or PDF.

And that's not even the end of it. You can add menu items to cancel, undo, redo 
and still be able to reuse the choices by using the actions `draw.modes`, 
`draw.widths`, `draw.colors` or `draw.shapes`.

```
"export": {
  "menu": [ {
    "class": "export-main",
    "menu": [ {
      "label": "Download",
      "menu": [ "PNG", "JPG", "CSV", "XLSX" ]
    }, {
      "label": "Annotate",
      "action": "draw",
      "menu": [ {
        "class": "export-drawing",
        "menu": [ {
            label: "Size ...",
            action: "draw.widths",
            widths: [ 5, 20, 30 ] // replaces the default choice
        }, {
          "label": "Edit",
          "menu": [ "UNDO", "REDO", "CANCEL" ]
        }, {
          "label": "Save",
          "format": "PNG"
        } ]
      } ]
    } ]
  } ]
}
```

### Annotation settings

Since 1.2.1 it's also possible to set some of the annotation options without the 
need to re-define the whole menu structure. You can easily adjust the choice of 
modes, colors, widths or shapes, and set the defaults when entering the 
annotation mode.

Following setup shows you all available settings. If you don't have the 
`drawing` property at all, it will falls back to the defaults.

```
"export": {
  "drawing": {
    "enabled": true, // Flag for `action: "draw"` menu items to toggle it's visibility
    "shapes": [ "test.svg" ], // Choice of shapes offered in the menu (shapes are being loaded from the shapes folder)

    "width": 2, // Width of the pencil and line when entering the annotation mode
    "widths": [ 2, 10, 20 ], // Choice of widths offered in the menu

    "color": "#000000", // Color of the pencil, line, text and shapes when entering the annotation mode
    "colors": [ "#000000", "#FF0000" ] // Choice of colors offered in the menu

    "opacity": 1, // Opacity of the pencil, line, text and shapes when entering the annotation mode
    "opacities": [ 1, 0.8, 0.6, 0.4, 0.2 ] // Choice of opacity offered in the menu

    "menu": [ ... ], // Shown menu when entering the annotation mode

    "mode": "pencil", // Drawing mode when entering the annotation mode "pencil", "line" and "arrow" are available
    "modes": [ "pencil" , "line", "arrow" ], // Choice of modes offered in the menu
    "arrow": "end", // position of the arrow on drawn lines; "start","middle" and "end" are available
  }
}
```

If you need to filter the drawn elements, you can pass the `reviver` method in 
your global configuration, or pass it to the `capture` method if you export 
manually. For example, to hide all free labels you can simply do something like 
the following:

```
"export": {
  "menu": ["PNG"],
  "reviver": function(obj) {
    if ( obj.className == "amcharts-label" ) {
      obj.opacity = 0;
    }
  }
}
```

### Delay the capturing before export

In some cases you may want to delay the capturing of the current chart snapshot 
to highlight the current value. For this you can simply define the 'delay' 
property in your menu item:

```
"export": {
  "delay": 3,

  // or specifically on individual menu items

  "menu": [{
    "label": "PNG",
    "format": "PNG",
    "delay": 3
  }]
}
```

### Events

Since version 1.1.7 the plugin introduces some events you can use. For example 
the `afterCapture` event allows you to add some texts or images which can't be 
seen on the regular chart but only the generated export. Use it to watermark 
your exported images.

```
"export": {
  "afterCapture": function(menuConfig) {
      var text = new fabric.Text("This is shown on exported image only", {
        top: 50,
        left: 100,
        family: this.setup.chart.fontFamily,
        size: this.setup.chart.fontSize * 2
      });
      this.setup.fabric.add(text);
  },

  // or specifically on individual menu items

  "menu": [{
    "label": "PNG",
    "format": "PNG",  
    "afterCapture": function(menuConfig) {
        var text = new fabric.Text("This is shown on exported image only", {
          top: 50,
          left: 100,
          family: this.setup.chart.fontFamily,
          size: this.setup.chart.fontSize * 2
        });
        this.setup.fabric.add(text);
    }
  }]
}
```

### Exporting to PDF

When exporting to PDF, you can set and modify the content of the resulting 
document. I.e. add additional text and/or modify image size, etc.

To do that, you can use menu item's `content` property.

Each item in `content` represents either a text line (string) or an exported 
image.

To add a text line, simply use a string. It can even be a JavaScript variable or 
a function that returns a string.

To include exported image, use `image: "reference"`.

Additionally, you can add `fit` property which is an array of pixel dimensions, 
you want the image to be scaled to fit into.

Here's an example of such export menu item:

```
{
  "format": "PDF",
  "content": [ "Saved from:", window.location.href, {
    "image": "reference",
    "fit": [ 523.28, 769.89 ] // fit image to A4
  } ]
}
```

pageSize | a string or { width: number, height: number }
pageOrientation | by default we use portrait, you can change it to landscape if you wish
pageMargins | [left, top, right, bottom] or [horizontal, vertical] or just a number for equal margins

## Styling the export menu

The plugin comes with a default CSS file `export.css`. You just need to include 
it on your page.

Feel free to override any styles defined in it, create your own version and 
modify as you see fit.

If you choose to modify it, we suggest creating a copy so it does not get 
overwritten when you update amCharts or plugin.


## Plugin API

We explained how you can define custom functions to be executed on click on 
export menu items.

Those functions can tap into plugin's methods to augment it with some custom 
functionality.

Here's an example:

```
"export": {
  menu: [ {
    label: "JPG",
    click: function() {
      this.capture({},function() {
        this.toJPG( {}, function( data ) {
          this.download( data, "image/jpg", "amCharts.jpg" );
        });
      });
    }
  } ]
}
```

The above will use plugin's internal `capture` method to capture it's current 
state and `toJPG()` method to export the chart to JPEG format.

Yes, you're right, it's the exact equivalent of just including "JPG" string. The 
code is here for the explanatory purposes.

Here's a full list of API functions available for your consumption:

Function | Parameters | Description
-------- | ---------- | -----------
toJPG | (object) options, (function) callback | Prepares a JPEG representation of the chart and passes the binary data to the callback function
toPNG | (object) options, (function) callback | Prepares a PNG representation of the chart and passes the binary data to the callback function
toSVG | (object) options, (function) callback | Prepares a SVG representation of the chart and passes the binary data to the callback function
toPDF | (object) options, (function) callback | Prepares a PDF representation of the chart and passes the binary data to the callback function
toJSON | (object) options, (function) callback | Prepares a JSON and passes the plain data to the callback function
toCSV | (object) options, (function) callback | Prepares a CSV and passes the plain data to the callback function
toXLSX | (object) options, (function) callback | Prepares a XLSX representation of the chart and passes the binary data to the callback function
toBlob | (object) options, (function) callback | Prepares a BLOB and passes the instance to the callback function
toCanvas | (object) options, (function) callback | Prepares a Canvas and passes the element to the callback function
toArray | (object) options, (function) callback | Prepares an Array and passes the data to the callback function
toImage | (object) options, (function) callback | Generates an image element which holds the output in an embedded base64 data url

## Fallback for IE9

Unfortunately, Internet Explorer 9 has restrictions in place that prevent the 
download of locally-generated files. In this case the plugin will place the 
generated image along download instructions directly over the chart area.

To avoid having a bigger payload by including senseless polyfills to your site, 
you may need to add following metatag in your `<head>` of your HTML document.

```
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
```

This feature will kick in by default. If you want to disable it simply pass 
`false` to the `fallback` parameter.

```
"export": {
  fallback: false
}
```

In case you want to change our default messages you can modify it like 
following.

```
"export": {
  fallback: {
    text: "CTRL + C to copy the data into the clipboard.",
    image: "Rightclick -> Save picture as... to save the image."
  }
}
```

## Requirements

This plugin requires at least 3.13 version of JavaScript Charts, JavaScript
Stock Chart or JavaScript Maps.

The export will also need relatively recent browsers.

IE10 and up are supported.

Partial support for IE9; Fallback mechanism.
