下面显示的是一个时间序列条形图,在plotly.js中带有一个范围选择器。
在其中,我试图找出如何按周对值进行分组,但似乎无法实现这一点。更改时间范围选择时,plotly.js中是否有设置按周将其分组?我似乎无法弄清楚是否有可能。
这是他们提供的主要文档页面,我尝试了许多与完成此操作有关的设置,但无法弄清。
var days = (function(start,count){
var days = [];
var MSday = 1000 * 60 * 60 * 24;
for(var i = 0; i < count; i++){
days.push(new Date(+start + i*MSday));
}
return days;
})(new Date(2018,0,1),100);
function vals(){
var vals = [];
for(var i = 0; i < 100; i++){
vals.push((Math.random() * 2 * i) | 0);
}
return vals;
}
var selectorOptions = {
buttons: [{
step: 'month',
stepmode: 'backward',
count: 1,
label: '1m'
}, {
step: 'month',
stepmode: 'backward',
count: 6,
label: '6m'

如何在图表上按周而不是按天创建6个月的选择组?
答案 0 :(得分:2)
布莱米!有一个更简单的选择...
使用7天:
step: 'day',
stepmode: 'backward',
count: 7,
label: '1w'
答案 1 :(得分:1)
显然这不是内置的。如果它是内置的或在某个时候内置的,请在注释或其他答案中指出。
我唯一确定可行的选择是使用.on('plotly_relayout', function () {
进入中继事件,并从范围选择器按钮中获取参数(似乎有限制,如果有确定原点的更好方法,也请让我知道,我将在此处进行更新),然后大致基于此来按周对日期进行分类并调整图中的x和y值。
这只是作为概念证明的基本实现。在生产中使用它需要对代码进行重构,以在设计和页面实现方面与现有数据结构一起使用。
这里发生了很多事情。基本上,它将遍历日期集以创建将包含每周数据的星期天框(请注意,它仍然缺少显示更新以显示它是从开始日期开始的一周)。一旦有了垃圾箱,它将对每个垃圾箱范围内的日期进行求和。然后,它使用restyle
替换数据集。如果选择的范围不是6m,则它将使用一部分备份数据,因为会按计划修改阵列,因此,如果没有备份副本,则每次备份时都会覆盖一个副本,因此它将覆盖数据。使用。
请参见下面的有效演示。
