Add buttons in chart of Highcharts at runtime

问题

I need to add some custom buttons (with onclick events), without overwrite the exporting buttons value, 'cause I wanna include new buttons without lost the custom buttons previously defined in chart (my chart already has custom buttons defined), all this at runtime, in a Highcharts chart using this object:

$('container').highcharts()

Is this possible?

回答1:

You can add custom buttons using the exporting object:

    exporting: {
        buttons: {
            customButton: {
                text: 'Custom Button',
                onclick: function () {
                    alert('You pressed the button!');
                }
            },
           anotherButton: {
                text: 'Another Button',
                onclick: function () {
                    alert('You pressed another button!');
                }
            }
        }
    }

EDIT: He wanted to add buttons after config

    var chart = $('#container').highcharts();
    normalState = new Object();
    normalState.stroke_width = null;
    normalState.stroke = null;
    normalState.fill = null;
    normalState.padding = null;
    normalState.r = null;

    hoverState = new Object();
    hoverState = normalState;
    hoverState.fill = 'red';

    pressedState = new Object();
    pressedState = normalState;

    var custombutton = chart.renderer.button('button', 74, 10, function(){
        alert('New Button Pressed');
    },null,hoverState,pressedState).add();

new fiddle: http://jsfiddle.net/NxK39/2/ answer using technique from Highcharts: replace custom button image on hover

回答2:

This seems much more clean (due to being able to align properly):

chart.renderer.button('Reset zoom', null, null, chart.resetZoom, {
   zIndex: 20
}).attr({
   align: 'right',
   title: 'Reset zoom level 1:1'
}).add(chart.zoomGroupButton).align({
   align: 'right',
   x: -10,
   y: 10
}, false, null);

if you need to pass any information simply do the following:

chart.renderer.button('Reset zoom', null, null, function(){ myFunction(chart) }, {
   zIndex: 20
}).attr({
   align: 'right',
   title: 'Reset zoom level 1:1'
}).add(chart.zoomGroupButton).align({
   align: 'right',
   x: -10,
   y: 10
}, false, null);
