我需要在折线图中添加一个滑块，允许用户跳转到x轴上的特定日期。我已经在图表中添加了一个滑块，但由于某种原因，它无法正常工作，我不知道问题出在哪里。有人能帮忙吗？
https://jsfiddle.net/samwhite/t5sabeyv/1/
afterSetExtremes: function(e) {
$("#slider-range").slider("values", 0, 1975 + e.min);
$("#slider-range").slider("values", 1, 1975 + e.max);
$("#year").val(Math.round(e.min + 1975) +
" - " + Math.round(e.max + 1975));
}
$("#slider-range").slider({
range: true,
min: 1975,
max: 2020,
values: [1975, 2020],
slide: function(event, ui) {
$("#year").val(ui.values[0] + " - " + ui.values[1]);
chart.xAxis[0].setExtremes(ui.values[0] - 1975, ui.values[1] - 1975)
}
});
$("#year").val($("#slider-range").slider("values", 0) +
" - " + $("#slider-range").slider("values", 1));
下面是一个我正在努力实现的相同行为的例子https://jsfiddle.net/uvat8u05/27/
任何帮助都将不胜感激。
您需要使用Date.UTC在图表中设置新的间隔。因此，您可以在滑块功能内更新代码，即：
slide: function(event, ui) {
$("#amount").val(ui.values[0] + " - " + ui.values[1]);
chart.xAxis[0].setExtremes(Date.UTC(ui.values[0] ,0,1),Date.UTC(ui.values[1] ,0,1) )
}
然后，如果没有定义获取错误图表，那么我必须使用this.axis.chart来访问系列和工具提示。
工作代码:
