Question

I want to hide default buttons (“Export” & “Print”) in highchart export options.

you can have demo at http://jsfiddle.net/fXHB5/3496/ in this link there are 3 buttons
1. Custom Button
2. Export button
3. print Button.

In this case I want to show only first button and hide “Export button” & “print Button”

Answer 1

you can access each button preference with something like this:

exporting: {
    buttons: {
        printButton: {
            symbol: 'circle'
        },
        exportButton: {
            enabled: false
        }    
    }
}

an expandable example with your custom button would be:

exporting: {
    buttons: {
        printButton: {
            enabled: false
        },
        exportButton: {
            enabled: false
        },
        custom: {
            symbol: 'diamond',
            x: -62,
            symbolFill: '#B5C9DF',
            hoverSymbolFill: '#779ABF',
            _titleKey: 'printButtonTitle',
            onclick: function () {
                alert('click!')
            }
        }
    }
}
