Google Visualization API:折线图 - 隐藏Y轴中的负值

Question

我使用Google Visualization API绘制折线图.以下是代码:

google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawCharts);
function drawCharts() {
    // Total Coupon View
    var data_total_users = new google.visualization.DataTable();
    data_total_users.addColumn('string', 'Total Users');
    data_total_users.addColumn('number', 'User Count');

    data_total_users.addRows(7);
    data_total_users.setValue(0, 0, 'Sunday');
    data_total_users.setValue(0, 1, 10);
    data_total_users.setValue(1, 0, 'Monday');
    data_total_users.setValue(1, 1, 4);
    data_total_users.setValue(2, 0, 'Tuesday');
    data_total_users.setValue(2, 1, 3);
    data_total_users.setValue(3, 0, 'Wednesday');
    data_total_users.setValue(3, 1, 7);
    data_total_users.setValue(4, 0, 'Thursday');
    data_total_users.setValue(4, 1, 8);
    data_total_users.setValue(5, 0, 'Friday');
    data_total_users.setValue(5, 1, 10);
    data_total_users.setValue(6, 0, 'Saturday');
    data_total_users.setValue(6, 1, 10);
    var chart = new google.visualization.LineChart(document.getElementById('chart_users_total'));
    chart.draw(data_total_users, {width: 1000, height: 400, title: '', hAxis: {title: ''}});
}

结果如下:

问题是:如何删除-0.5,-1.0？另外,我想在Y轴上有整数(例如0,1,2,3 ......).我应该添加哪个参数？

Answer 1

在您的chart.draw调用中,添加:vAxis:{viewWindow:{min:0}}
