Google图表忽略了格式化程序

Question

我尝试将格式化程序应用于数据表列但忽略它。

function drawMultSeries(orderData) {
    var dataTable = new google.visualization.DataTable();
    dataTable.addColumn('string', Translator.trans('company.dashboard.order_chart.days'));
    dataTable.addColumn('number', Translator.trans('company.dashboard.orders_title'));
    dataTable.addColumn('number', Translator.trans('company.dashboard.order_chart.expenses'));
    dataTable.addRows(orderData);


    var formatter = new google.visualization.NumberFormat(
        {prefix: 'test'});
    formatter.format(dataTable, 2);

    var options = {
        allowHtml: true,
        title: Translator.trans('company.dashboard.orders_title'),
        hAxis: {
            title: Translator.trans('company.dashboard.order_chart.days'),
            viewWindow: {
                min: [7, 30, 0],
                max: [17, 30, 0]
            }
        },
        vAxes: {
            1: { format: 'currency' }
        },
        colors: ['#8fd5ba', '#1C2C3A'],
        series: {
            0: { type: 'bars', targetAxisIndex: 0 },
            1: { type: 'area', targetAxisIndex: 1, areaOpacity: 0.07 }
        }
    };

    var chart = new google.visualization.ComboChart(
        document.getElementById('chart-orders'));

    $('.dashboard-chart-loading').hide();
    $('#chart-orders').show();

    chart.draw(dataTable, options);
}

我希望右侧的Axis有＆＃34;测试＆＃34;字符串前缀为任何值。

Answer 1

您正在格式化数据，将鼠标悬停在折线图上的某个数据点上，您将看到测试。

格式化轴...

        vAxes: {
            1: { format: 'test $#,##0.00' }
        },

    google.load('visualization', '1', {packages: ['corechart']});
    google.setOnLoadCallback(drawMultSeries);

    function drawMultSeries() {
        var dataTable = new google.visualization.DataTable();
        dataTable.addColumn('string', 'days');
        dataTable.addColumn('number', 'title');
        dataTable.addColumn('number', 'expenses');
        dataTable.addRows([
          ['18/09', 1, 160],
          ['22/09', 1, 250]
        ]);

        var formatter = new google.visualization.NumberFormat(
            {prefix: 'test'});
        formatter.format(dataTable, 2);

        var options = {
            allowHtml: true,
            title: 'title',
            hAxis: {
                title: 'days',
                viewWindow: {
                    min: [7, 30, 0],
                    max: [17, 30, 0]
                },
            },
            vAxes: {
                1: { format: 'test $#,##0.00' }
            },
            colors: ['#8fd5ba', '#1C2C3A'],
            series: {
                0: { type: 'bars', targetAxisIndex: 0 },
                1: { type: 'area', targetAxisIndex: 1, areaOpacity: 0.07 }
            }
        };

        var chart = new google.visualization.ComboChart(
            document.getElementById('chart-orders')
        );

        chart.draw(dataTable, options);
    }
