nchart for node.js inspired by [Chart.js][].
NOTE: nchart currently just imports Chart.js(v1.x) and it's hacked for node.
var Canvas = require('canvas')
, canvas = new Canvas(800, 800)
, ctx = canvas.getContext('2d')
, Chart = require('nchart')
, fs = require('fs');
new Chart(ctx).Pie(
[
{
"value": 50
, "color": "#E2EAE9"
}
, {
"value": 100
, "color": "#D4CCC5"
}
, {
"value": 40
, "color": "#949FB1"
}
]
, {
scaleShowValues: true
, scaleFontSize: 24
}
);
canvas.toBuffer(function (err, buf) {
if (err) throw err;
fs.writeFile(__dirname + '/pie.png', buf);
});
$ npm install -g nchart
