如何实施Google饼图(带有图例显示和相应的值) [英] How to implement Google Pie chart(with legend display and corresponding values)
本文介绍了如何实施Google饼图(带有图例显示和相应的值)的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我使用数据库中的json数据创建了Google饼图。饼图是用传说名称创建的,但我也希望显示具有价值的传说,这是除了饼图以外的价值的名称。我尝试了不同的东西,但我完全被这个难住了。
我正在执行的Google饼图代码是(片段): -
function drawChart(data)
{
var hi_cnt = data.length;
var gdata = new google.visualization.DataTable();
var total = 0;
gdata.addColumn('string','Task');
gdata.addColumn('数字','每小时');
gdata.addRows(hi_cnt);
for(var i = 0; i< hi_cnt; i ++)
{
gdata.setCell(i,0,data [i] ['name']);
gdata.setCell(i,1,parseInt(data [i] ['count']));
var options = {
title:'按类型划分的数量',
'width':750,
' height':450,
backgroundColor:'#EEE',
legend:{position:'right'},
areaOpacity:1.0,
sliceVisibilityThreshold:0,
// vAxis:{格式:'#$'},
// hAxis:{title:'????',titleTextStyle:{color:'blue'},slantedText:true,viewWindow:{min: 39,max:52}},
//颜色:['CCFFCC','66CC66','FF9999'],
//动画:{duration:1000,easing:'out'}
};
var chart = new google.visualization.PieChart(document.getElementById('outer_tableDiv'));
chart.draw(gdata,options);
}
function getHealthReport()
{
var dataString = {auth_token:sessionStorage.auth_token,};
var mh_url = MH_HOST +'/reports/get_health_issues_report.json';
$ .ajax(
{
类型:POST,
url:mh_url,
data:dataString,
dataType: json,
成功:函数(数据)
{
drawChart(数据);
},
错误:函数(数据)
{
alert(fail);
}
});
}
任何人都可以请我帮忙..
<我猜你可以尝试以下方法: - $ / $>
var total = 0;
for(var i = 0; i< data.getNumberOfRows(); i ++){
total + = data.getValue(i,1);
//获取数据
var label = data.getValue(i,0);
var value = data.getValue(i,1);
var percent = Math.ceil(1000 * value / total)/ 10;
//这将为显示创建图例列表
lis [i] = document.createElement('li');
lis [i] .id ='legend_'+ data.getValue(i,0);
lis [i] .innerHTML ='< div class =legendMarkerstyle =background-color:'+ colors [i] +';>< / div>'+ label +': '+ value +'('+ percent +'%)< / span>';
legend.appendChild(lis [i]);
}
请让我知道它是否正确。
I have created google pie chart using json data from database. The pie chart was created with legend name, but i want also display legend with value,that is the name with value besides the piechart.I am trying out different stuffs but I am completely stumped by this.
The google pie chart code which I am implementing is(snippet):-
function drawChart(data)
{
var hi_cnt = data.length;
var gdata = new google.visualization.DataTable();
var total = 0;
gdata.addColumn('string', 'Task');
gdata.addColumn('number', 'Hours Per Day');
gdata.addRows(hi_cnt);
for (var i= 0;i < hi_cnt; i++)
{
gdata.setCell(i, 0, data[i]['name']);
gdata.setCell(i, 1, parseInt(data[i]['count']));
}
var options = {
title: 'Number of Issues By Type',
'width': 750,
'height': 450,
backgroundColor: '#EEE',
legend: {position: 'right'},
areaOpacity: 1.0,
sliceVisibilityThreshold:0,
//vAxis: {format: '# $'},
//hAxis: {title: '????', titleTextStyle: {color: 'blue'}, slantedText: true, viewWindow: {min: 39, max: 52}},
//colors: ['CCFFCC', '66CC66', 'FF9999'],
//animation: {duration: 1000, easing: 'out'}
};
var chart = new google.visualization.PieChart(document.getElementById('outer_tableDiv'));
chart.draw(gdata, options);
}
function getHealthReport()
{
var dataString = {auth_token: sessionStorage.auth_token,};
var mh_url = MH_HOST + '/reports/get_health_issues_report.json';
$.ajax(
{
type: "POST",
url: mh_url,
data: dataString,
dataType: "json",
success: function (data)
{
drawChart(data);
},
error: function (data)
{
alert("fail");
}
});
}
Can anyone please help me..
解决方案
My guess is you can try the following :-
var total = 0;
for (var i = 0; i < data.getNumberOfRows(); i++) {
total += data.getValue(i, 1);
// get the data
var label = data.getValue(i, 0);
var value = data.getValue(i, 1);
var percent = Math.ceil(1000 * value / total) / 10;
// This will create legend list for the display
lis[i] = document.createElement('li');
lis[i].id = 'legend_' + data.getValue(i, 0);
lis[i].innerHTML = '<div class="legendMarker" style="background-color:' + colors[i] + ';"></div>' + label + ': ' + value + ' (' + percent + '%)</span>';
legend.appendChild(lis[i]);
}
Please let me know if it is right.
