[Solved]-Calling Reset Zoom manually-Highcharts

1. hide the original reset button

 chart: {
            resetzoombutton: {
                    theme: {
                        display: 'none'
                    }
                }
            }

2. take care of the event

 buttons: {
                    resetbutton: {
                        symbol: 'url(redo_icon.svg)',
                        _titlekey: "resetzoom",
                        y: 20,
                        x: -20,
                        onclick: function () {
                            this.xaxis[0].setextremes(null,null);
                            this.yaxis[0].setextremes(null,null)
                        }
                    }
                }

we had a similar situation - user zooms, we add a 'save this zoom stage' button, user clicks the button, we save the new min/max time, but now we have to make the reset zoom button disappear.

this code did it and the button returns if the user zooms even further afterwards:

chart.resetzoombutton.hide();
chart.resetzoombutton = chart.resetzoombutton.destroy();

i just called the button's click event and it worked fine.

given: v_chart is variable for highcharts chart;

if (typeof v_chart.resetzoombutton !== 'undefined') {
    v_chart.resetzoombutton.element.onclick();
}

if you want to reset the zoom on an external button click then do it as follows:

$("#yourownzoombtnid").click(function(){ 

    $('.highcharts-button').click();
});

if you want to hide the inbuilt reset button of highcharts then you can do it as follows:

xaxis: { categories: xaxiscategories
                ,events: {
      aftersetextremes: function() {
        $('.highcharts-button').hide();
      }
    }}

thanks kalyan

as suggested here

chart.zoom()

but keep in mind that calling chart.zoom() does not trigger chart.events.selection event. which is triggered if you click on "reset button" manually or programmatically $('.highcharts-button').click();

pawel's suggestion of calling

chart.xaxis[0].setextremes(null,null);

does work, btw, as shown here: http://jsfiddle.net/tvhg6/

however, although the chart zooms out, the resetzoom button is still hanging around, not sure how to hide it. calling chart.resetzoombutton.hide() hides it, but it does so permanently.
