Custom Highcharts Context Menu Button Appearing in Every Chart on Page

Question

I have a page with several charts, and I need to be able to add specific options to the exporting context menu for each chart. This is the code I am using:

Answer 1

I found another possiblity to add it only to one chart. Add following to the chart where you want to extend the context menu

       exporting: {
            buttons: {
                contextButton: {
                    menuItems: [

                    ]
                }
            }
        },

. Now you are able to extend the chart dynamicly with a method like

 function (button) {
    var userMenu = this.chart.userOptions.exporting.buttons.contextButton.menuItems;
    if (userMenu.length === 0) {
        var menuItems = Highcharts.getOptions().exporting.buttons.contextButton.menuItems;
        for (var itemIndex in menuItems) {
            userMenu.push(menuItems[itemIndex]);
        }
    }
    userMenu.push(button);
};

. Where this.chart points to the chart which context menu should be extended
