Quick start
To generate JPG image a chart from chart instance, create index.js file with the following content:
// require file system and jsdom
var fs = require('fs');
// For jsdom version 10 or higher.
// Require JSDOM Class.
var JSDOM = require('jsdom').JSDOM;
// Create instance of JSDOM.
var jsdom = new JSDOM('<body><div id="container"></div></body>', {runScripts: 'dangerously'});
// Get window
var window = jsdom.window;
// For jsdom version 9 or lower
// var jsdom = require('jsdom').jsdom;
// var document = jsdom('<body><div id="container"></div></body>');
// var window = document.defaultView;
// require anychart and anychart export modules
var anychart = require('anychart')(window);
var anychartExport = require('anychart-nodejs')(anychart);
// create and a chart to the jsdom window.
// chart creating should be called only right after anychart-nodejs module requiring
var chart = anychart.pie([10, 20, 7, 18, 30]);
chart.bounds(0, 0, 800, 600);
chart.container('container');
chart.draw();
// generate JPG image and save it to a file
anychartExport.exportTo(chart, 'jpg').then(function(image) {
fs.writeFile('anychart.jpg', image, function(fsWriteError) {
if (fsWriteError) {
console.log(fsWriteError);
} else {
console.log('Complete');
}
});
}, function(generationError) {
console.log(generationError);
});
Run the following command in the command line:
$ node index.js
>> Complete
To generate PDF image a chart from Java Script string, create index.js file with the following content:
// require file system and jsdom
var fs = require('fs');
// require only anychart export module
var anychartExport = require('anychart-nodejs');
// define javascript string that represent code of chart creating
var chart = "var chart = anychart.pie([10, 20, 7, 18, 30]); chart.bounds(0, 0, 800, 600); chart.container('container'); chart.draw()";
// generate PDF image and save it to a file
anychartExport.exportTo(chart, 'pdf').then(function(image) {
fs.writeFile('anychart.pdf', image, function(fsWriteError) {
if (fsWriteError) {
console.log(fsWriteError);
} else {
console.log('Complete');
}
});
}, function(generationError) {
console.log(generationError);
});
Run the following command in the command line:
$ node index.js
