Dynamically adding AND REMOVING Y Axis

[Pat]

Using ASPNet Core EJ2 Charts

We are adding a second Line series dynamically using this javascript

function addLineSeries(seriesData, axisLabel) {

            var chart = document.getElementById("chart").ej2_instances[0];

            chart.removeSeries(1);

            chart.addAxes([{

                name: 'secondAxis',

                title: axisLabel,

                opposedPosition: true

            }]);

            chart.addSeries([{

                type: 'Line',

                dataSource: seriesData,

                xName: 'Date', 

                yName: 'Value',

                yAxisName: "secondAxis",

                marker: {

                    visible: true,

                    height: 10,

                    width: 10

                }

            }]);

        }

The second series gets added fine as does the Y Axis, however if we call it a second time for a different data set we need to remove the previous dynamic series using chart.removeSeries(1); that works but we are unable to remove the dynamically added second Y Axis. 

How do we remove the second Y Axis? 

Where is the documentation for the EJ2 client side library?

Thanks
