谷歌图表显示所有标签 [英] Google Charts show all labels

问题描述

我想在页面上显示水平条形图.我正在使用谷歌图表库.我遇到的问题是某些标签被遗漏了.有没有办法强制显示所有标签?

I would like to display a horizontal bar chart on a page. I am using the google charts library. The issue I am having is that some labels are being missed off. Is there a way of forcing all labels to display?

google.charts.load('current', {packages: ['corechart', 'bar']});
google.charts.setOnLoadCallback(drawBasic);

function drawBasic() {

  var data = google.visualization.arrayToDataTable([
    ['City', '2010 Population', ],
    ['New York City, NY', 8175000],
    ['Los Angeles, CA', 3792000],
    ['Chicago, IL', 2695000],
    ['Houston, TX', 2099000],
    ['Philadelphia, PA', 1526000],
    ['New York City2, NY', 8175000],
    ['Los Angeles2, CA', 3792000],
    ['Chicago2, IL', 2695000],
    ['Houston2, TX', 2099000],
    ['Philadelphia2, PA', 1526000]
  ]);

  var options = {
    title: 'Population of Largest U.S. Cities',
    chartArea: {
      width: '50%'
    },
    hAxis: {
      title: 'Total Population',
      minValue: 0
    },
    vAxis: {
      title: 'City'
    }
  };

  var chart = new google.visualization.BarChart(document.getElementById('chart_div'));

  chart.draw(data, options);
}

演示 jsfiddle

您会注意到在上面的代码中有 11 个标签/值.显示所有值，但缺少所有其他标签.我希望显示所有标签.

You will notice in the above code that there are 11 labels/values. All values are displayed but every other label is missing. I would like all labels to be displayed.

推荐答案

可以设置chartArea的具体大小和位置

you can set specific size and placement of the chartArea

为每个轴标签和标题留出空间

to allow room for each axis label and title

连同图表标题、图例等...

along with the chart title, legend, etc...

看下面的例子，添加了backgroundColor来突出每个区域

see following example, added backgroundColor to highlight each area

google.charts.load('current', {
  callback: drawBasic,
  packages: ['corechart']
});

function drawBasic() {
  var data = google.visualization.arrayToDataTable([
    ['City', '2010 Population', ],
    ['New York City, NY', 8175000],
    ['Los Angeles, CA', 3792000],
    ['Chicago, IL', 2695000],
    ['Houston, TX', 2099000],
    ['Philadelphia, PA', 1526000],
    ['New York City2, NY', 8175000],
    ['Los Angeles2, CA', 3792000],
    ['Chicago2, IL', 2695000],
    ['Houston2, TX', 2099000],
    ['Philadelphia2, PA', 1526000]
  ]);

  var options = {
    backgroundColor: 'cyan',
    title: 'Population of Largest U.S. Cities',

    // total size of chart
    height: 600,
    width: 900,

    // adjust size of chart area
    chartArea: {
      backgroundColor: 'magenta',

      // allow 70px for hAxis title and ticks
      height: 480,

      // allow 200px for vAxis title and ticks
      left: 200,

      // allow 50px for chart title
      top: 50,

      // allow 200px for legend on right
      width: 500
    },

    colors: ['yellow'],
    hAxis: {
      title: 'Total Population',
      minValue: 0
    },
    vAxis: {
      title: 'City'
    }
  };

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