Morris js Display values in percentage format
提问by Aaron Ullal
I am drawing some charts for a school project pulling data from a mysql database. Here is what I've done so far:
我正在为一个从 mysql 数据库中提取数据的学校项目绘制一些图表。这是我到目前为止所做的：
DONUT CHARTS
甜甜圈图
JS CODE:
JS代码：
Morris.Donut({
element: 'donut-quanti',
data: [
{label: "USE FACEBOOK", value: <?php echo $fb_yes;?> },
{label: "DON'T USE FACEBOOK", value: <?php echo $fb_no;?>}
]
});
BAR CHARTS
条形图
JS CODE:
JS代码：
Morris.Bar({
element: 'bars-status',
data: [
{x:'RARELY',a:<?php echo $fb_rar;?>},
{x:'EV WEEK.',a:<?php echo $fb_ew;?>},
{x:'EV DAY',a:<?php echo $fb_ed;?>},
{x:'MULT. TIMES PER DAY',a:<?php echo $fb_mtd;?>}
],
xkey:'x',
ykeys:'a',
labels:['TOTAL']
});
Is there a way to display the numeric values (rapresented by the php variables $fb_*) IN PERCENTAGE FORMAT from javascript code(not echoing variable/total * 100 in php ) ?
有没有办法从 javascript 代码中以百分比格式显示数值（由 php 变量 $fb_* 表示） （在 php 中不回显变量/总计 * 100）？

For the donut you need to use the formatterparameter
对于甜甜圈，您需要使用formatter参数
formatter: function (value, data) { return (value/total *100) + '%'; }
See: http://morrisjs.github.io/morris.js/donuts.html

For the bar you need to use hover callback
对于栏，您需要使用悬停回调
hoverCallback: function (index, options, content) {
var row = options.data[index];
//assumes you have already calculated the total of your own dataset
return (value/total *100)+'%';
}

To add the percentage symbol, please use this property. I did not find this in the docs but it works perfectly. postUnits: ["%"]
要添加百分比符号，请使用此属性。我没有在文档中找到这个，但它工作得很好。帖子单位：["%"]

donutChartOptions = {
resize: true,
colors: ["#8e54e9", "#4776e6"],
formatter: function (value) { return (value) + '%'; }
}
