Google图表上的最大值和最小值

Question

如何在Google Chart上设置最大值和最小值？

我试过这个没有成功:

vAxis: {
    viewWindowMode:'explicit',
        viewWindow: {
            max:3000,
            min:500
        }
    }

这是我正在使用的所有代码:

<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
      google.load("visualization", "1.1", {packages:["bar"]});
      google.setOnLoadCallback(drawChart);
      function drawChart() {
        var data = google.visualization.arrayToDataTable([
          ['Year', 'Sales', 'Expenses', 'Profit'],
          ['2014', 1000, 400, 200],
          ['2015', 1170, 460, 250],
          ['2016', 660, 1120, 300],
          ['2017', 1030, 540, 350]
        ]);

        var options = {
          chart: {
            title: 'Company Performance',
            subtitle: 'Sales, Expenses, and Profit: 2014-2017',
          },
          vAxis: {
            viewWindowMode:'explicit',
            viewWindow: {
              max:3000,
              min:500
            }
        },
          bars: 'vertical' // Required for Material Bar Charts.
        };

        var chart = new google.charts.Bar(document.getElementById('barchart_material'));

        chart.draw(data, options);
      }
</script>

随着Material Charts的发布,Google正在修改指定选项的方式.这些选项的结构尚未最终确定,因此Google为经典选项结构提供了转换器功能,并且建议您使用它而不是使用可能在将来更改的选项.

因此,您可以通过以下两种方式之一解决问题:

1. 您可以使用转换功能,如Google建议的那样(您可以在此jsfiddle或Google的官方文档中看到此方法(请注意链接标题底部的注释))

      google.load("visualization", "1.0", {packages:["bar"]});
      google.setOnLoadCallback(drawChart);
      function drawChart() {
        var data = google.visualization.arrayToDataTable([
          ['Year', 'Sales', 'Expenses', 'Profit'],
          ['2014', 1000, 400, 200],
          ['2015', 1170, 460, 250],
          ['2016', 660, 1120, 300],
          ['2017', 1030, 540, 350]
        ]);

        var options = {
          chart: {
            title: 'Company Performance',
            subtitle: 'Sales, Expenses, and Profit: 2014-2017',
          },
          vAxis: {
            viewWindowMode:'explicit',
            viewWindow: {
              max:3000,
              min:500
            }
        },
          bars: 'vertical', // Required for Material Bar Charts.
            width: 800,
            height: 600
        };

        var chart = new google.charts.Bar(document.getElementById('barchart_material'));
          

        chart.draw(data, google.charts.Bar.convertOptions(options));
      }

    <script type="text/javascript" src="https://www.google.com/jsapi?autoload={'modules':[{'name':'visualization','version':'1','packages':['corechart']}]}"></script>
    
          <div id="barchart_material"></div>
      
    

2. 您可以继续使用将来可能会更改的选项.如果您不关心图表中断,您要查找的选项是axes.y.all.range.{min,max}.你可以在这个jsfiddle中看到该选项.

google.load("visualization", "1.0", {
    packages: ["bar"]
});
google.setOnLoadCallback(drawChart);

function drawChart() {
    var data = google.visualization.arrayToDataTable([
        ['Year', 'Sales', 'Expenses', 'Profit'],
        ['2014', 1000, 400, 200],
        ['2015', 1170, 460, 250],
        ['2016', 660, 1120, 300],
        ['2017', 1030, 540, 350]
    ]);

    var options = {
        chart: {
            title: 'Company Performance',
            subtitle: 'Sales, Expenses, and Profit: 2014-2017',
        },
        axes: {
            y: {
                all: {
                    range: {
                        max: 3000,
                        min: 500
                    }
                }
            }
        },
        bars: 'vertical', // Required for Material Bar Charts.
        width: 800,
        height: 600
    };

    var chart = new google.charts.Bar(document.getElementById('barchart_material'));


    chart.draw(data, options);
}

<script type="text/javascript" src="https://www.google.com/jsapi?autoload={'modules':[{'name':'visualization','version':'1','packages':['corechart']}]}"></script>
<div id="barchart_material"></div>
