Pseudo code
                      
var chart = new Cosfire.Chart("chart-container", {....});

let aDataSeries = { plotAs: "bar",
                    points: [{ xLabel: "January", y: 3550 },
                      { xLabel: "February", y: 3000},
                      { xLabel: "March", y: 8550},
                      { xLabel: "April", y: 5900},
                      { xLabel: "May", y: 6500},
                      { xLabel: "June", y: 4550}]
                  };
// Set Data. Setting Array of DataSeries
chart.setData([aDataSeries]);

chart.render(function onRenderCompleted() {
  // chart rendered
}));
Let us checkout the example below. Here in the example there is only one DataSeries of type "Bar" and there are 6 DataPoints in it. DataPoints are set through points property of DataSeries. We add more than one DataSeries to create multi-series Chart very easily.
