我有一個CSV文件:Highchart,CSV和48小時時間軸,顯示過去48個時數據
2011-01-11, 0:00, 4
2011-01-11, 0:05, 2
2011-01-11, 0:10, 6
2011-01-11, 0:15, 8
...
2011-01-12, 0:00, 4
2011-01-12, 0:05, 2
...
2011-01-13, 20:00, 4
2011-01-13, 20:05, 2
...
什麼是最好的做法,只顯示最近48時數據?
這裏是CSV解析器:
$.get('data.csv', function(data) {
// Split the lines
var lines = data.split('\n');
$.each(lines, function(lineNo, line) {
var items = line.split(',');
// header line containes categories
if (lineNo == 0) {
$.each(items, function(itemNo, item) {
if (itemNo > 0) options.xAxis.categories.push(item);
});
}
// the rest of the lines contain data with their name in the first position
else {
var series = {
data: []
};
$.each(items, function(itemNo, item) {
if (itemNo == 0) {
series.name = item;
} else {
series.data.push(parseFloat(item));
}
});
options.series.push(series);
}
});
是否修改此解析器僅加載從CSV持續288線(24小時制數據)的好辦法?如果是的話,我該怎麼做?
