我们正在使用Highcharts开发一些图表。
并且我们将series.events.afterAnimate
与xAxis.max
值结合使用。
但是,例如,当我们有从Januari到9月的点,但是xAxis.max值直到12月,则afterAnimate
函数在到达12月时被调用。.
但是我们希望在绘制所有有效点时进行回调,而不是达到最大值...
这可能吗?
答案 0 :(得分:1)
之所以会这样,是因为clipPath的宽度默认等于绘图区域的宽度。要对其进行更改,可以覆盖Highcharts.Series.animate
方法,并将clipPath width设置为特定系列的宽度。
编辑:
此外,请注意,当clipPath的宽度更短且动画的持续时间相同时,动画会慢得多。为了使外观更好,必须缩短时间-可以根据序列宽度进行计算并在图表load
事件中进行更新。
查看下面的演示和代码:
代码:
(function(H) {
H.Series.prototype.animate = function(init) {
var series = this,
chart = series.chart,
clipRect,
animation = H.animObject(series.options.animation),
sharedClipKey;
// Initialize the animation. Set up the clipping rectangle.
if (init) {
series.setClip(animation);
// Run the animation
} else {
sharedClipKey = this.sharedClipKey;
clipRect = chart[sharedClipKey];
if (clipRect) {
clipRect.animate({
width: series.group.getBBox().width,
x: 0
}, animation);
}
if (chart[sharedClipKey + 'm']) {
chart[sharedClipKey + 'm'].animate({
width: chart.plotSizeX + 99,
x: 0
}, animation);
}
// Delete this function to allow it only once
series.animate = null;
}
}
})(Highcharts);
Highcharts.setOptions({
chart: {
events: {
load: function() {
var chart = this,
series = chart.series[0],
seriesWidth = series.graph.getBBox().width,
duration = (seriesWidth / chart.plotWidth) * series.options.animation.duration;
chart.series[0].update({
animation: {
duration: duration
}
});
}
}
},
