我正在尝试将时间序列作为 x 轴添加到 C3 中的两线图。不幸的是，我不知道该怎么做。它给出了错误“x is not defined for id = "Dates"”，尽管我已尝试尽可能地遵循 C3 的时间序列图表示例。
这是代码，有什么想法吗？
request.addEventListener('readystatechange', function () {
if (this.readyState == 4) {
var throughputReceived = JSON.parse(this.responseText).throughputReceived,
throughputSent = JSON.parse(this.responseText).throughputSent,
date = JSON.parse(this.responseText).date,
chart,
length = throughputReceived.length;
for (var i = 0; i < length; i++) {
throughputReceived[i] /= 1000000;
throughputSent[i] /= 1000000;
// date[i] = moment(date[i]).format("YYYY MM DD hh ss");
}
throughputReceived.unshift('Throughput Received (Mbps)');
throughputSent.unshift('Throughput Sent (Mbps)');
date.unshift('Dates');
chart = c3.generate({
bindto: container,
data: {
x: date,
columns: [date, throughputReceived, throughputSent]
},
axis: {
x: {
// label: 'Test No.'
type: 'timeseries',
tick: {
format: '%Y %m %d %h %s'
}
},
y: {
label: {
text: 'Throughput (Mbps)',
position: 'outer-top'
},
tick: {
format: d3.format('.2f')
}
}
}
});
}
});
最佳答案
您定义的 x 轴错误。
您必须定义列的标题，而不是引用您的日期数组。
date.unshift('Awesome-Column');
...
data: {
x: 'Awesome-Column',
columns: [date, throughputReceived, throughputSent]
},
