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

To add button use options for chart. Then you can set for each chart different set of options: http://jsfiddle.net/4uP5y/4/

Get default buttons:

var buttons = Highcharts.getOptions().exporting.buttons.contextButton.menuItems;

buttons.push({
    text: "Tokyo Only Option",
    onclick: HelloWorld
});

And set them for a chart:

exporting: {
    buttons: {
        contextButton: {
            menuItems: buttons // or buttons.slice(0,6)
        }
    }
},
