如何删除值 Google 图表上的负号?

How to remove negative symbol on values Google Charts?

我有一个柱形图并且工作正常,但我想始终显示正数,但我强制负数到顶部和底部的 "divide" 条。

他举个例子:

这是我的代码

google.load('visualization','1.1',{packages:['corechart']});
google.setOnLoadCallback(function(){
var GoogleChart=new google.visualization.ColumnChart(document.getElementById( 'chart' ));   
var data = google.visualization.arrayToDataTable([
    ["Age","Male","Female"],
    ["<15",{"v":0,"f":"0%"},{"v":0,"f":"0%"}],
    ["15-20",{"v":8.3333333333333,"f":"8,3333333333333%"},{"v":0,"f":"0%"}],
    ["20-25",{"v":75,"f":"75%"},{"v":-8.3333333333333,"f":"8,3333333333333%"}],
    ["25-30",{"v":0,"f":"0%"},{"v":0,"f":"0%"}],
    ["30-35",{"v":0,"f":"0%"},{"v":0,"f":"0%"}],
    ["35-40",{"v":0,"f":"0%"},{"v":0,"f":"0%"}],
    ["40-45",{"v":8.3333333333333,"f":"8,3333333333333%"},{"v":0,"f":"0%"}],
    ["45-50",{"v":0,"f":"0%"},{"v":0,"f":"0%"}],
    ["50-55",{"v":0,"f":"0%"},{"v":0,"f":"0%"}],
    ["55-60",{"v":0,"f":"0%"},{"v":0,"f":"0%"}],
    [">60",{"v":0,"f":"0%"},{"v":0,"f":"0%"}]
]);
new google.visualization.NumberFormat({"pattern":"#,##%"}).format(data, 1); 
new google.visualization.NumberFormat({"pattern":"#,##%"}).format(data, 2); 
var options ={
    "isStacked":true,
    "hAxis":{
        "title":"age"
    },
    "vAxis":{
        "title":"Percentage",
        "format":"#,##%",
        "viewWindowMode":"explicit",
        "viewWindow":{
            "min":-100,
            "max":100
        }
    }
};
GoogleChart.draw(data, options);

我不知道如何删除负号(“-”)。 谢谢

P.S: Google Charts 1.1

google 可视化模式格式是 ICU pattern set 的子集。通过这种方式,您可以为正数和负数指定子模式以避免减号(因为如果未指定负子模式,默认情况下您将获得减号前缀):

format: "#,##%;#,##%"

不幸的是,这在可视化中不起作用——它抱怨“太多percent/permills”——但因为%只不过是“乘以 100 并显示为百分比 " - 然后您只需添加 ,00% 作为字符串后缀即可:

vAxis:{
   format:"#,##',00%';#,##',00%'",
   ...
}
new google.visualization.NumberFormat({"pattern":"#,##',00%';#,##',00%'"}).format(data, 1); 
new google.visualization.NumberFormat({"pattern":"#,##',00%';#,##',00%'"}).format(data, 2); 

减号现已从 vAxis 和工具提示中移除。
