var config = require('./config.json');
var acs = new AwsCloudWatchChart(config);
acs.getChart().then(function(chart){
chart.save('image.png').then(function(filename){
//// filename should be == 'image.png' this is your chart.
}
});
or
acs.getChart().then(function(chart){
chart.get().then(function(image){
//// image is png image.
}
});
