getProperty() function used to get a particular property value

                      // Read title text value from yAxis of the Chart
document.getElementById('myButton')
.addEventListener("click", function(){
  let axisY = chart.axesY[0];
  let titleElement = axisY.getProperty('title');
  alert(titleElement.getProperty('text'));
});                 
                  

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.
