Highcharts plotLine拖动xAxis事件 [英] Highcharts plotLine drag xAxis event
问题描述
我想在xAxis上拖一个 plotLine
并检测这个变化。
有人可以举个例子吗?

这是我到目前为止所尝试过的。点击事件不会触发。
通过这种方法,我想添加dragstart,dragend等事件来启用拖动功能。

您可以使用Highcharts translate函数。
请参阅工作示例: http:// jsfiddle。 net / VXTeR / 1 /
var line,
clickX,
clickY;
var start = function(e){
$(document).bind({
'mousemove.line':step,
'mouseup .line':stop
});
clickX = e.pageX - line.translateX;
// clickY = e.pageY - line.translateY; //取消注释,如果剧情也应该垂直移动
}
var step = function(e){
line.translate(e.pageX - clickX,e.pageY - clickY )
}
var stop = function(){
$(document).unbind('。line');
Highcharts回调
<$ $ {code $>'code> $('#container')。highcharts(options,function(chart){
$ b $ line = chart.xAxis [0] .plotLinesAndBands [0] .svgElem .attr({
stroke:'yellow'
})
.css({
'cursor':'pointer'
})
.translate (0,0)
.on('mousedown',start);
});
I would like to drag a plotLine
on xAxis and detect this change.
Can someone please provide an example ?

@DiMono
Here is what I have tried so far. The click event is not firing. By this approach I would like to add, dragstart, dragend etc events to enable drag functionality.

H.Chart.prototype.callbacks.push(function(chart){
H.addEvent(chart.xAxis[0].plotLinesAndBands[0].svgElem,'click',function(e){
console.log('click from plugin');
});
});
}(Highcharts));
$(document).ready(function(){
var chart = new Highcharts.Chart({
chart : {
renderTo: 'container'
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
plotLines: [{
color: '#FF0000',
width: 2,
value: 5.5
}]
},
series: [{
data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}]
});
});

You can prepare it in JavaScript with the Highcharts translate function.
See working example: http://jsfiddle.net/VXTeR/1/
var line,
clickX,
clickY;
var start = function (e) {
$(document).bind({
'mousemove.line': step,
'mouseup.line': stop
});
clickX = e.pageX - line.translateX;
//clickY = e.pageY - line.translateY; //uncomment if plotline should be also moved vertically
}
var step = function (e) {
line.translate(e.pageX - clickX, e.pageY - clickY)
}
var stop = function () {
$(document).unbind('.line');
}
Highcharts callback
$('#container').highcharts(options, function(chart){
line = chart.xAxis[0].plotLinesAndBands[0].svgElem.attr({
stroke: 'yellow'
})
.css({
'cursor': 'pointer'
})
.translate(0, 0)
.on('mousedown', start);
});
