如何在谷歌图表中删除工具提示

Question

我正在研究Google图表，但是我遇到了一些问题

我正在绘制一个多于10个数据的甜甜圈图，所以当数据显示的宽度超过它时，会在

这样的工具提示中显示该情况

我不想要

我想做的事情就像有多少个标头一样，让它不要将其推入工具提示中

google.charts.load('current', {
  'packages': ['corechart'],
  'language': 'hi_IN'
});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
  var data = google.visualization.arrayToDataTable([
    ["Outlet", "Amount"],
    ["S0001", 7153214],
    ["S0002", 1319026],
    ["S0003", 1497004],
    ["S0004", 1597004],
    ["S0005", 1697004],
    ["S0006", 1797004],
    ["S0007", 1897004],
    ["S0008", 13897004],
    ["S0009", 2097004],
    ["S0010", 1597004],
    ["S00011", 1698604]
  ]);

  var options = {
    pieHole: 0.6,
    legend: {
      position: 'right',
    },
    width: 'auto',

    height: 'auto'
  };

  var chart = new google.visualization.PieChart(document.getElementById('donutchart'));
  chart.draw(data, options);
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
<div id="donutchart" style="width: 100%; height: 550px;"></div>

我不想删除我只想一次显示的图例，而是想在工具提示中显示，用户必须单击以查看其他图例

要检查的数据

[["Outlet","Amount"],["CHEF BAKERS BROOKFIELD",738999],["CHEF BAKERS ARAKERE",106050],["CHEF BAKERS AMEENPUR",89358],["CHEF BAKERS AYYAPPA NGR",80088],["Chef Bakers Bellandur",321705],["CHEF BAKERS BRIGADE METROPOLIS",65088],["CHEF BAKERS BAGMANE CBP",145432],["CHEF BAKERS CHANDAPURA",92830],["DIVYA SREE TECHNO PARK",82946],["Chef Bakers Doddanekkundi",92590],["CHEF BAKERS SIDDAPURA",115142],["CHEF BAKERS ECITY",163745],["CHEF BAKERS VYDEHI",84367],["CHEF BAKERS HARLUR ROAD",101337],["Chef Bakers Hennur Main Road",18045],["CHEF BAKERS HSR LAYOUT",358232],["CHEF BAKERS BOTANICAL GARDEN",22256],["CHEF BAKERS KADUBEESANAHALLI",277964],["CHEF BAKERS COFFEE BOARD",164906],["Chef Bakers Kaggadasapura",73045],["Chef Bakers Koramangala",79381],["CHEF BAKERS KASAVANAHALLI",424056],["Chef Bakers Marathahalli 1",115410],["Chef bakers Marathahalli 2",105703],["Chef Bakers Mahadevapura",209014],["CHEF BAKERS BEL LAYOUT",58661],["CHEF BAKERS MG ROAD",70005],["CHEF BAKERS MANYATA TECH PARK",105590],["CHEF BAKERS NAGAWARA",47832],["CHEF BAKERS PRESTIGE SHANTHINIKETAN",135772],["CHEF BAKERS PRITECH",301201],["RGA TECH PARK",64525],["CHEF BAKERS RAMANTHAPUR",62752],["CHEF BAKERS RR NAGAR",94200],["Chef Bakers Kadugodi",353045],["CHEF BAKERS SARJAPURA ROAD",84425],["CHEF BAKERS SINGASANDRA",60735],["CHEF BAKERS SPICE GARDEN",135243],["Chef Bakers Whitefield",427212],["CHEF BAKERS YELAHANKA",293061]]

Answer 1

您可以使用选项-> legend.maxLines
为图例添加更多行。

注意：此选项仅适用于-> legend.position = top

请参阅以下工作片段...

google.charts.load('current', {
  'packages': ['corechart'],
  'language': 'hi_IN'
}).then(function () {
  var data = google.visualization.arrayToDataTable([
    ["Outlet", "Amount"],
    ["S0001", 7153214],
    ["S0002", 1319026],
    ["S0003", 1497004],
    ["S0004", 1597004],
    ["S0005", 1697004],
    ["S0006", 1797004],
    ["S0007", 1897004],
    ["S0008", 13897004],
    ["S0009", 2097004],
    ["S0010", 1597004],
    ["S00011", 1698604]
  ]);

  var options = {
    pieHole: 0.6,
    legend: {
      position: 'top',
      maxLines: 5
    },
    width: 'auto',
    height: 'auto'
  };

  var chart = new google.visualization.PieChart(document.getElementById('donutchart'));
  chart.draw(data, options);
});

<div id="donutchart" style="width: 100%; height: 550px;"></div>

您可能想尝试一下，

legend: {
  position: 'top',
  maxLines: data.getNumberOfRows()
}

或

legend: {
  position: 'top',
  maxLines: data.getNumberOfRows()/4
}

这样做将始终为您提供足够的行数，这样您就可以将所有图例放在一页上，而不必滚动

google.charts.load('current', {
  'packages': ['corechart'],
  'language': 'hi_IN'
});
google.charts.setOnLoadCallback(drawChart);

function drawChart() {
  var data = google.visualization.arrayToDataTable([
    ["Outlet", "Amount"],
    ["S0001", 7153214],
    ["S0002", 1319026],
    ["S0003", 1497004],
    ["S0004", 1597004],
    ["S0005", 1697004],
    ["S0006", 1797004],
    ["S0007", 1897004],
    ["S0008", 13897004],
    ["S0009", 2097004],
    ["S0010", 1597004],
    ["S00011", 1698604],
    ["S00012", 1698604],
    ["S00013", 1698604],
    ["S00014", 1698604],
    ["S00015", 1698604],
    ["S00016", 1698604],
    ["S00017", 1698604],
    ["S00018", 1698604],
    ["S00019", 1698604]
  ]);
  


  var options = {
    pieHole: 0.3,
    legend: {
      position: 'top',
      maxLines: data.getNumberOfRows()
    },
    width: 'auto',

    height: 'auto'
  };
  var chart = new google.visualization.PieChart(document.getElementById('donutchart'));
  chart.draw(data, options);
}

Answer 3

问题是由于图表中的图例占用的空间大于包含元素中可用的空间。

如果要删除图例（我不建议您删除图例，因为没有图则变得非常不清楚），可以在设置中设置position: 'none'。

var options = {
  pieHole: 0.6,
  legend: {
    position: 'none',
  },
  width: 'auto',
  height: 'auto'
};
