Toggle multiple Axes on/off

I have a chart with 3 series, graphed from a common SfChart's SecondaryAxis.
I've been trying to figure out how I could toggle between displaying the 3 series graphed from a common SecondaryAxis and displaying the 3 series, each with their own axis.
If I add a YAxis to each series, it seems that neither setting IsEnabled = False or Visibility = Collapsed will return the series to be graphed to the common SecondaryAxis.

Any idea how I could toggle multiple axes on/off?

Hi Alan, 
Thanks for contacting Syncfusion Support. 
We have achieved your requirement (toggle between the series YAxis and chart secondary axis) with checkbox by applying null for series YAxis as shown in below code.  
Please find the code snippet, 
public partial class MainWindow : Window 
        NumericalAxis axis1; 
        NumericalAxis axis2; 
        NumericalAxis axis3; 
        public MainWindow() 
            axis1 = new NumericalAxis() 
                Interval = 10, 
                Foreground = chart.Series[0].Interior , 
                Minimum = 10, 
                ShowGridLines = false 
            axis2 = new NumericalAxis() 
                Interval = 10, 
                Foreground = chart.Series[1].Interior, 
                Minimum = 10, 
                ShowGridLines = false 
            axis3 = new NumericalAxis() 
                Interval = 10, 
                Foreground = chart.Series[2].Interior, 
                Minimum = 10, 
                ShowGridLines = false 
        private void CheckBox_Checked(object sender, RoutedEventArgs e) 
            if(chart.SecondaryAxis.Visibility != Visibility.Visible) 
                chart.SecondaryAxis.Visibility = Visibility.Visible; 
                line1.YAxis = null; 
                line2.YAxis = null; 
                line3.YAxis = null; 
        private void CheckBox_Unchecked(object sender, RoutedEventArgs e) 
            chart.SecondaryAxis.Visibility = Visibility.Collapsed; 
            line1.YAxis = axis1; 
            line2.YAxis = axis2; 
            line3.YAxis = axis3; 

Please find the output screenshot,
