There are two possible solutions:
The easiest option would be to show/hide and zoom with extra buttons. So you would add some buttons to your page and execute a function like:
//Edit made a mistake selecting the chart:
You should create your chart and add it to the Array when you are creating it. For example:
var charts = new Array();
var chart = new Highcharts.StockChart(opts);
charts.push(chart);
Then for the function:
//Set xAxis extremes (zoom)
for (var i = 0; i < charts.length; i++) {
charts[i].xAxis[0].setExtremes(startDate, endDate);
}
to change the zoom. Showing and hiding of a series is also pretty simple:
So you could just call charts[i].series[0].hide(); to hide the first Series
Another possibility would be to use the Highcharts events to start a similar function when a user clicks on the chart.
For example on the legend: Highstock Options Reference
And for the Zoom:
xAxis : {
events : {
afterSetExtremes : afterSetExtremes
},
},

Please familiar with example which synchronizes three charts and have unzoom button.
$(function() {
var chart1;
var chart2;
var chart3;
var controllingChart;
var defaultTickInterval = 5;
var currentTickInterval = defaultTickInterval;
$(document).ready(function() {
function unzoom() {
chart1.options.chart.isZoomed = false;
chart2.options.chart.isZoomed = false;
chart3.options.chart.isZoomed = false;
chart1.xAxis[0].setExtremes(null, null);
chart2.xAxis[0].setExtremes(null, null);
chart3.xAxis[0].setExtremes(null, null);
}
//catch mousemove event and have all 3 charts' crosshairs move along indicated values on x axis
function syncronizeCrossHairs(chart) {
var container = $(chart.container),
offset = container.offset(),
x, y, isInside, report;
container.mousemove(function(evt) {
x = evt.clientX - chart.plotLeft - offset.left;
y = evt.clientY - chart.plotTop - offset.top;
var xAxis = chart.xAxis[0];
//remove old plot line and draw new plot line (crosshair) for this chart
var xAxis1 = chart1.xAxis[0];
xAxis1.removePlotLine("myPlotLineId");
xAxis1.addPlotLine({
value: chart.xAxis[0].translate(x, true),
width: 1,
color: 'red',
//dashStyle: 'dash',
id: "myPlotLineId"
});
//remove old crosshair and draw new crosshair on chart2
var xAxis2 = chart2.xAxis[0];
xAxis2.removePlotLine("myPlotLineId");
xAxis2.addPlotLine({
value: chart.xAxis[0].translate(x, true),

var xAxis3 = chart3.xAxis[0];

xAxis3.addPlotLine({
value: chart.xAxis[0].translate(x, true),
width: 1,
color: 'red',
//dashStyle: 'dash',
id: "myPlotLineId"
});
//if you have other charts that need to be syncronized - update their crosshair (plot line) in the same way in this function.
});
}
//compute a reasonable tick interval given the zoom range -
//have to compute this since we set the tickIntervals in order
