Google Chart:如何在面积图上添加缩放按钮 [英] Google Chart: How to add zoom buttons on Area chart

问题描述

我想在 AreaChart 顶部添加缩放按钮，如 AnnotationChart.我搜索了相同的内容，但没有得到解决方案.谁能告诉我解决办法?我需要这样的按钮:

谢谢

解决方案

你必须手动添加按钮，
单击时，使用 state 属性

在范围过滤器上设置可见范围

 rangeFilter.setState({范围: {开始:currentRange.range.start，结束:新日期(currentRange.range.start.getTime()+可见范围)}});

请参阅以下工作片段，
每个按钮表示以毫秒为单位的可见范围，
单击时，在过滤器上设置范围...

google.charts.load('current', {包:['控件'，'corechart']}).then(函数(){var data = new google.visualization.DataTable();data.addColumn('日期', '日期');data.addColumn('number', 'Positive');data.addColumn('number', 'Negative');数据.addRows([[新日期(2017, 11, 20), 10, null],[新日期(2017, 11, 21), 5, null],[新日期(2017, 11, 22), 0, 0],[新日期(2017, 11, 23), null, -5],[新日期(2017, 11, 24), null, -10],[新日期(2017, 11, 25), null, -5],[新日期(2017, 11, 26), 0, 0],[新日期(2017, 11, 27), 10, null],[新日期(2017, 11, 28), 5, null],[新日期(2017, 11, 29), 0, 0],[新日期(2018, 0, 20), 00, null],[新日期(2018, 0, 21), 5, null],[新日期(2018, 0, 22), 0, 0],[新日期(2018, 0, 23), null, -5],[新日期(2018, 0, 24), null, -10],[新日期(2018, 0, 25), null, -5],[新日期(2018, 0, 26), 0, 0],[新日期(2018, 0, 27), 00, null],[新日期(2018, 0, 28), 5, null],[新日期(2018, 0, 29), 0, 0],[新日期(2018, 1, 20), 10, null],[新日期(2018, 1, 21), 5, null],[新日期(2018, 1, 22), 0, 0],[新日期(2018, 1, 23), null, -5],[新日期(2018, 1, 24), null, -10],[新日期(2018, 1, 25), null, -5],[新日期(2018, 1, 26), 0, 0],[新日期(2018, 1, 27), 10, null],[新日期(2018, 1, 28), 5, null],[新日期(2018, 1, 29), 0, 0],[新日期(2018, 2, 20), 10, null],[新日期(2018, 2, 21), 5, null],[新日期(2018, 2, 22), 0, 0],[新日期(2018, 2, 23), null, -5],[新日期(2018, 2, 24), null, -10],[新日期(2018, 2, 25), null, -5],[新日期(2018, 2, 26), 0, 0],[新日期(2018, 2, 27), 10, null],[新日期(2018, 2, 28), 5, null],[新日期(2018, 2, 29), 0, 0],[新日期(2018, 3, 20), 10, null],[新日期(2018, 3, 21), 5, null],[新日期(2018, 3, 22), 0, 0],[新日期(2018, 3, 23), null, -5],[新日期(2018, 3, 24), null, -10],[新日期(2018, 3, 25), null, -5],[新日期(2018, 3, 26), 0, 0],[新日期(2018, 3, 27), 10, null],[新日期(2018, 3, 28), 5, null],[新日期(2018, 3, 29), 0, 0],[新日期(2018, 4, 20), 10, null],[新日期(2018, 4, 21), 5, null],[新日期(2018, 4, 22), 0, 0],[新日期(2018, 4, 23), null, -5],[新日期(2018, 4, 24), null, -10],[新日期(2018, 4, 25), null, -5],[新日期(2018, 4, 26), 0, 0],[新日期(2018, 4, 27), 10, null],[新日期(2018, 4, 28), 5, null],[新日期(2018, 4, 29), 0, 0],[新日期(2018, 5, 20), 10, null],[新日期(2018, 5, 21), 5, null],[新日期(2018, 5, 22), 0, 0],[新日期(2018, 5, 23), null, -5],[新日期(2018, 5, 24), null, -10],[新日期(2018, 5, 25), null, -5],[新日期(2018, 5, 26), 0, 0],[新日期(2018, 5, 27), 10, null],[新日期(2018, 5, 28), 5, null],[新日期(2018, 5, 29), 0, 0],[新日期(2018, 6, 20), 10, null],[新日期(2018, 6, 21), 5, null],[新日期(2018, 6, 22), 0, 0],[新日期(2018, 6, 23), null, -5],[新日期(2018, 6, 24), null, -10],[新日期(2018, 6, 25), null, -5],[新日期(2018, 6, 26), 0, 0],[新日期(2018, 6, 27), 10, null],[新日期(2018, 6, 28), 5, null],[新日期(2018, 6, 29), 0, 0],[新日期(2018, 9, 20), 10, null],[新日期(2018, 9, 21), 5, null],[新日期(2018, 9, 22), 0, 0],[新日期(2018, 9, 23), null, -5],[新日期(2018, 9, 24), null, -10],[新日期(2018, 9, 25), null, -5],[新日期(2018, 9, 26), 0, 0],[新日期(2018, 9, 27), 10, null],[新日期(2018, 9, 28), 5, null],[新日期(2018, 9, 29), 0, 0],[新日期(2018, 11, 20), 10, null],[新日期(2018, 11, 21), 5, null],[新日期(2018, 11, 22), 0, 0],[新日期(2018, 11, 23), null, -5],[新日期(2018, 11, 24), null, -10],[新日期(2018, 11, 25), null, -5],[新日期(2018, 11, 26), 0, 0],[新日期(2018, 11, 27), 10, null],[新日期(2018, 11, 28), 5, null],[新日期(2018, 11, 29), 0, 0],]);var rangeFilter = new google.visualization.ControlWrapper({controlType: 'ChartRangeFilter',容器 ID:'过滤范围'，选项: {过滤列索引:0，用户界面:{chartType: '面积图',图表选项:{图表区域:{宽度: '100%',左:36，右:18},身高:72}}}});var 图表 = 新的 google.visualization.ChartWrapper({chartType: '面积图',containerId: '图表区域',选项: {高度:280，传奇: {对齐:'结束'，位置:'顶部'},动画片: {持续时间:500，缓动:'在'，启动:真},图表区域:{高度:'100%',宽度: '100%',顶部:36，左:36，右:18，底部:36}}});$('#range-buttons button').on('click', function (sender) {var currentRange = rangeFilter.getState();var visibleRange = parseInt($(sender.target).data('range'));如果(isNaN(visibleRange)){rangeFilter.setState(null);} 别的 {rangeFilter.setState({范围: {开始:currentRange.range.start，结束:新日期(currentRange.range.start.getTime()+可见范围)}});}rangeFilter.draw();});var 仪表板 = 新的 google.visualization.Dashboard(document.getElementById('dashboard'));仪表板绑定(范围过滤器，图表)；仪表板.绘制(数据)；});

I want to add zoom buttons on top of AreaChart like AnnotationChart. I searched for the same but didn't get the solution. Can anyone tell me the solution? I require buttons like this:

Thanks

解决方案

you'll have to add the buttons manually,
when clicked, set the visible range on the range filter using the state property

  rangeFilter.setState({
    range: {
      start: currentRange.range.start,
      end: new Date(currentRange.range.start.getTime() + visibleRange)
    }
  });

see following working snippet,
each button represents the visible range in milliseconds,
when clicked, set the range on the filter...

google.charts.load('current', {
  packages: ['controls', 'corechart']
}).then(function () {
  var data = new google.visualization.DataTable();
  data.addColumn('date', 'Date');
  data.addColumn('number', 'Positive');
  data.addColumn('number', 'Negative');
  data.addRows([
    [new Date(2017, 11, 20), 10, null],
