我尝试使用时间序列轴创建一个简单的点线图，但图表没有渲染，我的浏览器控制台显示错误：
var chart = c3.generate({
bindto: '#chart',
data: {
json: [
{date: "2016-01-01", pageviews: 1},
{date: "2016-01-02", pageviews: 2},
{date: "2016-01-03", pageviews: 3},
{date: "2016-01-04", pageviews: 4},
{date: "2016-01-05", pageviews: 5}],
keys: {
x: 'date',
value: 'pageviews'
}
},
axis: {
x: {
type: 'timeseries',
tick: {
format: '%Y-%m-%d'
}
}
}
});
这是我的javascript：
Uncaught TypeError: targetKeys.forEach is not a function here's a jsfiddle使用D3和C3的未缩小来源并提供以下浏览器控制台错误： data.keys.value
答案 0 :(得分：2)
'pageviews'期待一个数组，所以只需将var chart = c3.generate({
bindto: '#chart',
data: {
json: [
{date: "2016-01-01", pageviews: 1},
{date: "2016-01-02", pageviews: 2},
{date: "2016-01-03", pageviews: 3},
{date: "2016-01-04", pageviews: 4},
{date: "2016-01-05", pageviews: 5}],
keys: {
x: 'date',
value: ['pageviews'] // needs to be an array
}
},
axis: {
x: {
type: 'timeseries',
tick: {
format: '%Y-%m-%d'
}
}
}
});
包装在方括号中，如下所示：
$now = Carbon::now();
$week = Carbon::now()->addWeek();
$month=Carbon::now()->addMonth();
