小编xor*_*ark的帖子

我正在使用Dan Grossman的 Twitter Bootstrap 日期范围选择器.

初始化时,可以设置startDate和endDate等预定义值.是否可以稍后以类似的方式手动更新值？

我想要做的是用我保存的过滤器"加载"日期范围选择器,其中包括开始和结束日期(不是通过定义预定义的范围).只是通过jQuery更新日期范围选择器的字段将不会更新日历的实际选择.

我想在初始化日期范围选择器时我应该这样做:

var reportrange = $('#reportrange').daterangepicker(),
DateRangePicker = reportrange.data('daterangepicker');

但是,如何使用DateRangePicker手动更新日期范围选择器和日历以及新选择的日期？

如何从amchart条形图中删除"js charts by amcharts"文本.有没有办法使用图表配置来做到这一点？请查看小提琴中的文字.

我想禁用/隐藏所有在x轴上的国家/地区标签，这是怎么可能的。

https://codepen.io/team/amcharts/pen/BrXwQL

chart.data = data;

// Create axes
var categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
categoryAxis.dataFields.category = "country";
categoryAxis.renderer.grid.template.disabled = true;

var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());
valueAxis.title.text = "Units sold (M)";
valueAxis.min = 0;
valueAxis.renderer.baseGrid.disabled = true;
valueAxis.renderer.grid.template.strokeOpacity = 0.07;

// Create series
var series = chart.series.push(new am4charts.ColumnSeries());
series.dataFields.valueY = "units";
series.dataFields.categoryX = "country";
series.tooltip.pointerOrientation = "vertical";

我已经查看了 amcharts 版本 4 ( https://www.amcharts.com/javascript-charts/ )的文档，但似乎无法找到如何将 y 轴格式化为货币。有关于以其他方式格式化 y 轴的文档，但货币似乎不是其中之一。有谁知道如何或从哪里开始？

到目前为止，我有上面的图表，只需要知道如何或在哪里将 y 轴格式化为货币。当您将鼠标悬停在格式化为货币的行上时，我目前有标签，因为这相当简单。这是我创建轴的函数：

function createAxisAndSeries(field, name, opposite) {
          const valueAxis = chart.yAxes.push(new am4charts.ValueAxis());

          const series = chart.series.push(new am4charts.LineSeries());
          series.dataFields.valueY = field;
          series.dataFields.dateX = 'date';
          series.strokeWidth = 2;
          series.yAxis = valueAxis;
          series.name = name;
          series.tooltipText = '{name}: [bold]${valueY}[/]';
          series.tensionX = 0.8;

          const interfaceColors = new am4core.InterfaceColorSet();

          valueAxis.renderer.line.strokeOpacity = 1;
          valueAxis.renderer.line.strokeWidth = 2;
          valueAxis.renderer.line.stroke = series.stroke;
          valueAxis.renderer.labels.template.fill = series.stroke;
          valueAxis.renderer.opposite = opposite;
          valueAxis.renderer.grid.template.disabled = true;

          }

我想知道在 AmCharts 中生成 amchart 图时是否有设置默认缩放的方法。

这是代码：

AmCharts.makeChart("chartdiv", {
  type: "serial",
  mouseWheelZoomEnabled: true,
  fontFamily: "Montserrat",
  path: "lib/amcharts/",
  theme: "light",
  fontSize: 12,
  categoryField: "category",
  precision: 0,
  decimalSeparator: ",",
  thousandsSeparator: ".",
  plotAreaFillAlphas: 0.11,
  plotAreaFillColors: "#61a1e6",
  zoomOutButtonColor: "#D6E7F9",
  sequencedAnimation: true,
  startDuration: 1,
  startEffect: "easeOutSine",
  balloonText: "[[title]] [[category]]:[[value]]",
  urlTarget: "#drill",
  categoryAxis: {
    autoRotateAngle: 0,
    autoWrap: false,
    gridPosition: "start",
    axisAlpha: 0.16,
    color: "#054bff",
    gridAlpha: 0,
    title: ""
  },
  chartScrollbar: {
    "enabled": true
  },
  trendLines: [],
  graphs: [
    [LEGEND]
  ],
  guides: [],
  valueAxes: [{
    [STACKED]
    id: "ValueAxis-1", …

我有一个使用 amCharts 创建函数图的小任务。

问题是我需要启用光标，但也需要禁用缩放，因此我可以将图形调整为背景图像。

文档说使用 禁用缩放chart.zoomEnabled = false;，但它似乎不起作用，我不知道我会遗漏什么。

谢谢！
