如果你的圖有兩條線以上,又要跟其他圖同步的話
['mousemove', 'touchmove', 'touchstart'].forEach(function (eventType) {
document.getElementById('container' + i).addEventListener(
eventType,
function (e) {
var chart,
point,
i,
event;
for (i = 0; i < Highcharts.charts.length; i = i + 1) {
chart = Highcharts.charts[i];
// Find coordinates within the chart
event = chart.pointer.normalize(e);
// Get the hovered point
point = chart.series[0].searchPoint(event, true);
if (point) {
point.highlight(e);
}
}
}
);
});
Highcharts.Pointer.prototype.reset = function () {
return undefined;
};
Highcharts.Point.prototype.highlight = function (event) {
event = this.series.chart.pointer.normalize(event);
this.onMouseOver(); // Show the hover marker
//這一段拿掉就正常了 this.series.chart.tooltip.refresh(this); // Show the tooltip
this.series.chart.xAxis[0].drawCrosshair(event, this); // Show the crosshair
};
function syncExtremes(e) {
var thisChart = this.chart;
if (e.trigger !== 'syncExtremes') { // Prevent feedback loop
Highcharts.each(Highcharts.charts, function (chart) {
if (chart !== thisChart) {
if (chart.xAxis[0].setExtremes) { // It is null while updating
chart.xAxis[0].setExtremes(
e.min,
e.max,
undefined,
false,
{ trigger: 'syncExtremes' }
);
}
}
});
}
};
排版有點亂抱歉....
