多个系列，多个图表
[英]Multiple series, multiple charts Highcharts
问题描述
i have to create a single chart showing different series with different type of chart (Ex: one data series with 'areaspline' and one data series with 'column'). 
我必须创建一个图表来显示具有不同图表类型的不同系列（例如：一个数据系列带有“ areaspline”，一个数据系列带有“ column”）。 I built a db with a lot of data, extracted by sql query into a json file 我建立了一个包含大量数据的数据库，通过SQL查询将其提取到一个json文件中
[
{ "name": "Test", "data": [2.8,2.8,2.8,2.7,2.7,] },
{ "name": "kwc", "data": [10,1,10,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] }
]
The json file is correct, but if i try to select the series for a chart with the $.each function it doesn't work! json文件是正确的，但是如果我尝试使用$ .each函数选择图表的序列，它将不起作用！ Here's my code 这是我的代码

array_push($result,$rows1);
print json_encode($result, JSON_NUMERIC_CHECK);

I tryed any kind of option, but anything gone right :( Any hope to display 1 chart, 2 or more data series and 2 or more type of charts? Thanks in advance 我尝试了任何一种选择，但是一切顺利：(是否希望显示1个图表，2个或更多数据系列以及2个或更多类型的图表？

It looks like your highcharts creation call is within your $.each function. 看来您的highcharts创建调用位于$ .each函数中。 So it will try to create 2 highcharts, but they both will be created in the same div, so you'll only end up with one. 因此，它将尝试创建2个图表，但它们都将在同一div中创建，因此最终只能得到一个。 Also, the way you are caculating datalength, it'll be 2. When, it appears, you'd like it to be the length of the actual data (which is different for your different series). 同样，计算数据长度的方式将是2。出现时，您希望它是实际数据的长度（对于不同的系列来说是不同的）。 I can't do the getJSON in a jsfiddle, so I'm assuming your PHP code is creating the json object you listed (and it looks like it would). 我无法在jsfiddle中执行getJSON，所以我假设您的PHP代码正在创建您列出的json对象（看起来像这样）。 You can lose the each loop alltogether and set your 2 series like this: 您可以完全失去每个循环，并像这样设置2个系列：
series: [{
name: 'Misure',
color: '#4572A7',
type: 'column',
yAxis: 1,
data: json[1].data,
tooltip: {
valueSuffix: ' Kw'
}
}, {
name: 'Temperature',
color: '#89A54E',
type: 'spline',
data: json[0].data,
tooltip: {
valueSuffix: '°C'
}
}]
