我试图让我的Highcharts / Highstock图表在rangeSelector设置为All时显示自定义刻度,我设置了这种方式,但是当我尝试使用图形的交互部分时,我会犯错误< / p>

我试图让图表在所有rangeSelector上每天有2个图表,显示当天的第一个点和一天中的最后一个点。我做错了什么?
编辑1:更新为完整配置,X轴正在被原始答案中断,自定义范围选择器上的刻度仍然有效。添加图片以显示正在进行的操作
答案 0 :(得分:1)
每次更改要在图表上显示的范围时,都会引发setExtremes
事件。它可以有几个起源:
事件的实际属性取决于其来源。如果您使用console.log(e)
输出活动,您会发现这两个来源不一样:
按钮单击范围选择器
{
trigger: "rangeSelectorButton",
rangeSelectorButton: {
text: "2Hour",
type: "hour",
count: 2,
},
...
}
在导航器中处理拖动
{
trigger: "navigator",
triggerOp: "navigator-drag",
rangeSelectorButton: undefined
}
如果你在导航器中拖动手柄,那么事件上没有rangeSelectorButton
,因为它没有意义:在这种情况下,没有按下按钮。
要修复错误,您可以在trigger
属性上添加检查:
xAxis: {
events: {
setExtremes: function(e) {
if (e.trigger === "rangeSelectorButton" && e.rangeSelectorButton.text === "All") {
...
}
}
}
如何解决实际问题
现在,真正的问题。您希望根据显示的内容更改刻度:每天的开头和结尾,或者如果不是一整天则更改小时。您可以使用代表所选时间范围的e.min
和e.max
执行该操作。
像这样:
setExtremes: function(e) {
var range = e.max - e.min;
// ticks spaced by one day or one hour
var ticksSpacing = range >= 86400 * 1000 ? 86400 : 3600;
this.update({
tickPositioner: function() {
var positions = [],
info = this.tickPositions.info;
for (var x = this.dataMin; x <= this.dataMax; x += ticksSpacing * 1000) { // Seconds * 1000 for ticks
positions.push(x);
};
positions.info = info;
return positions;
}
}, false);
}
