javascript - 谷歌图表中的 Y 轴以 "General 1, General 2"等递增 - Javascript

Question

我的 Google Charts 信息中心有问题。目前一切正常，除了柱形图在 Y 轴上显示字符串而不是整数。

我发现 Google 图表页面上的文档很难理解，所以如果我的代码中有错误，或者如果有更简单的方法我可以完成这些事情，我深表歉意。

我的 JS Fiddle 如下所示:https://jsfiddle.net/hm7q5peg/6/

    google.load('visualization', '1.0', {
    'packages': ['corechart','table', 'controls']
});
google.setOnLoadCallback(drawDashboard);

function drawDashboard() {
    // Using the jsapi, it's better to set the url
    // for the spreadsheet, then use setQuery() to
    // define the query that will provide your data.
    var url = '//docs.google.com/spreadsheet/ccc?key=1FOVmfesx7ATNe8qjWjkU2GbjBCBZxL0BRswJv6rcGPs&usp=drive_web&gid=1324373577';

    var query = new google.visualization.Query(url);
    query.setQuery('select B,C where B <> ""');

    // Send the query with a callback function
    query.send(handleQueryResponse);
}

function handleQueryResponse(response) {
    // Called when the query response is returned.
    if (response.isError()) {
        alert('Error in query: ' + response.getMessage() + ' ' + response.getDetailedMessage());
        return;
    }

    var data = response.getDataTable();

    var dashboard = new google.visualization.Dashboard(
    document.getElementById('dashboard_div'));

    // Create a range slider, passing some options
    var donutRangeSlider = new google.visualization.ControlWrapper({
        'controlType': 'NumberRangeFilter',
            'containerId': 'filter_div',
            'options': {
            'filterColumnLabel': 'Number Attended'
        }
    });


    // Create a pie chart, passing some options
    var pieChart = new google.visualization.ChartWrapper({
        'chartType': 'PieChart',
            'containerId': 'chart_div',
            'options': {
            'width': 300,
                'height': 300,
                'pieSliceText': 'value',
                'legend': 'right'
        }
    });

        //define a table
    var table = new google.visualization.ChartWrapper({
        'chartType': 'Table',
        'containerId': 'table_div',
        'options': {
            'width':'300px'
        }
    });

    //define the column chart
    var columnChart = new google.visualization.ChartWrapper({
        'chartType': 'ColumnChart',
        'containerId' : 'column_div',
    });

    // Establish dependencies, declaring that 'filter' drives 'pieChart',
    // so that the pie chart will only display entries that are let through
    // given the chosen slider range.
    dashboard.bind(donutRangeSlider, [pieChart, table, columnChart]);

    // Draw the dashboard.
    dashboard.draw(data);
}

如果您还没有这样做，请查看 ColumnChart Configuration Options看看你要玩什么。通过为垂直轴指定数字格式，您将获得数字。不幸的是，没有 bunch of additional code ，gViz 将决定您必须要查看分数，即使您的数据都是整数。

//define the column chart
var columnChart = new google.visualization.ChartWrapper({
    'chartType': 'ColumnChart',
    'options' : {
        'hAxis' : { 'title' : 'Student Name' },
        'legend' : {position: 'none' },
        'vAxis' : {format: 'short',
                   title: 'Number Attended'}
     },
    'containerId' : 'column_div',
});
