这里我有谷歌可视化数据表:
我如何在这里添加新行和在postion [0]上将字符串“Sum”放在位置1中将为10,在位置[2]中将为17,作为列的总和... < / p>
我开始编写代码,但我不会去任何地方......
我试试:
data.addRow();
for (var x=1, maxcol=data.getNumberOfColumns(); x < maxcol; x++) {
for y=1, maxrow=data.getNumberOfRows(); y < maxrow; y++) {
//WHAT NEXT ???
答案 0 :(得分:1)
试试这个:
var group = google.visualization.data.group(data, [{
type: 'number',
column: 0,
modifier: function () {return 0;}
}], [{
type: 'number',
column: 1,
aggregation: google.visualization.data.sum
}, {
type: 'number',
column: 2,
aggregation: google.visualization.data.sum
}]);
data.addRow(['Sum', group.getValue(0, 1), group.getValue(0, 2)]);
[编辑 - 添加代码以处理任意数量的列]
var groupColumns = [];
for (var i = 1; i < data.getNumberOfColumns(); i++) {
groupColumns.push({
type: 'number',
column: i,
aggregation: google.visualization.data.sum
});
}
var group = google.visualization.data.group(data, [{
type: 'number',
column: 0,
modifier: function () {return 0;}
}], groupColumns);
var row = ['Sum'];
for (var i = 1; i < group.getNumberOfColumns(); i++) {
row.push(group.getValue(0, i));
}
data.addRow(row);
