在下拉列表中显示从月份选择中选择的图表列表

Question

I am new to Highcharts and JS . For each month I have 5 charts. Here I am just sharing 5 example charts. I have to create a drop-down menu with each menu item for each month. When I select a month, all the charts for that month should be displayed in their divs. Default month should be current month. How could I do this?

Here's my code so far:

Answer 1

It's hard to prepare the perfect solution without taking a closer look on your whole application. The way of implementation hardly depends on your data structure and the chart types which you need to use, but I prepared the general example which shows how it could be done.

First I prepared the data so that it would be assigned for each month. Then I added the onchange listener on dropdown element, and update all charts by the new data from data object defined before, using built-in method Chart.update() . I left comments in my code, so you can read what happening "step by step", but If some part is not understandable or unclear for you, just ask in comment below this answer.

var months = {} // Will be the object with data structure for each month
var dropdown = document.getElementById('dropdown-months')
var options = dropdown.querySelectorAll('option')
var currentMonthId = new Date(Date.now()).getMonth()
var currentMonthName;

// Create random initial data
options.forEach(elem => {
  months[elem.value] = []
  for (var i = 0; i < 10; i++) {
    months[elem.value].push(Math.round(Math.random() * 100))
  }
  // Additionally, select current month in dropdown
  if (elem.value === Object.keys(months)[currentMonthId]) {
    currentMonthName = Object.keys(months)[currentMonthId]
    elem.selected = true
  }
})

dropdown.onchange = function() {
  var selectedMonth = this.value
  // Update all charts by new data
  Highcharts.charts.forEach(chart => {
    chart.update({
      series: [{
        data: months[selectedMonth]
      }]
    })
  })
}

// Generate charts and fill them by current month data
for (var i = 1; i <= 5; i++) {
  Highcharts.chart('container' + i, {
    series: [{
      data: months[currentMonthName]
    }]
  })
}
