卡住了!
我需要创建json结果highchart。我在这里找到了一些资源,但无法将其应用于工作。
我能得到的最接近的是这样做:
图表选项:
var options = {
chart: {
renderTo: 'tudo',
defaultSeriesType: 'column',
rightMargin: 80
},
title: {
text: 'Weekdays'
},
subtitle: {
text: 'Source: somewhere in a calendar'
},
xAxis: {
labels: {
enabled: false
}
},
yAxis: [
{
min: 0,
title: {
text: 'Amount'
}
},
{
linkedTo: 0,
opposite: true
}
],
series: []
};
ajax调用:
$.getJSON('ajax/calc.ajax.php', function(data) {
var series = [];
$.each(data, function(key, value) {
series.name = key;
series.data = value;
options.series.push(name);
});
var chart = new Highcharts.Chart(options);
});
highchart加载ok,用Series 1, Series 2 ....
但没有图形,他保持空白。(类似于:Demo).
想知道我是否错过了什么或一切。
感谢更新:我改变了sql,现在我正在使用2个字段,并且有了这个,图形工作完美,现在我只是想知道如果这样做它的ok。
header('Content-Type: application/json');
while(!$res->EOF){
//$json = array("group" => "Web", "action" => "list");
$json[$res->fields["DESMAR"]] = array(intval($res->fields["QTD"]));
//$json["users"] = array(array("name" => "JulioGreff", "status" => "online"));
$res->MoveNext();
}
echo json_encode($json);
中的 ajax调用 -
$.getJSON('ajax/calc.ajax.php', function(data) {
var series = []; // <---------------------- must be object not array
$.each(data, function(key, value) {
series.name = key;
series.data = value;
options.series.push(name); // <-------- it should be series not name
});
var chart = new Highcharts.Chart(options);
});
因此,它将是如下-
$.getJSON('ajax/calc.ajax.php', function(data) {
$.each(data, function(key, value) {
var series = {}; // <-------------------- moved and changed to object
series.name = key;
series.data = value;
options.series.push(series); // <-------- pushing series object
});
var chart = new Highcharts.Chart(options);
});
另外,考虑到您正在接收的JSON -
{"省":"TRANSFORMADOR 250 va 0 - 230 - 380 v/0, 24 v-0-48v","莫德罗":"TRANSFORMADOR",《马卡报》:"SEIT"、"英勇":"318.87 | 542.08","qtdade":"0"? ?}
你在$.each
做什么-
series.data = value;
没有意义
系列。data是一个数组。因此,它可以看起来像或者,如下所示-
[y1, y2, y3, ....] // array of numbers (which are y values)
或如下-
[[x1, y1], [x2, y2], [x3, y3], ....] // array of arrays of pair of numbers (x and y values)
或如下-
// array of objects which can have x and y values as properties
[{
name: 'Point 1',
color: '#00FF00',
y: 0
}, {
name: 'Point 2',
color: '#FF00FF',
y: 5
}]
因此,请确保您的PHP代码生成的JSON与上述数组之一匹配,然后$.each
中的series.data = value
将工作。
更新:对不起,我学过Java,从来没有学过PHP,所以不能帮你很多。但是,您可以尝试使用以下PHP代码,看看图表是否显示出来吗?
header('Content-Type: application/json');
$return_data = array(
array(array(10, 20), array(20, 30), array(56, 30), array(50, 20)),
array(array(10, 0), array(20, 10), array(56, 100), array(50, 40))
);
echo json_encode($return_data);
更新:在保持相同PHP的情况下呈现饼。
$.getJSON('ajax/calc.ajax.php', function(data) {
var series = { // <-------------------- create just one series object
type: 'pie',
data: [] //data array for new series
};
$.each(data, function(key, value) {
series.data.push([key, value[0]]);
});
options.series.push(series); // <-------- pushing series object
var chart = new Highcharts.Chart(options);
});
应该画一个饼状图
看起来问题出在PHP代码中。Highcharts希望一个系列遵循特定的格式。在您的情况下,事情解决(部分)是因为name
是它正在寻找的字段之一。然而,数据需要采用以下三种格式之一:
- y值的数组(例如
[0, 1, 2]
) - 数组的数组(x, y值;例:
[[0,0], [1,1], [2,2]]
) - 使用点属性集合的对象数组
我想你会想要最后一种格式。例如:
var series = [];
series.name = "series1";
series.data = {y: 10}; //very minimalistic example of the object format
options.series.push(name);
要使代码正常工作,您可能需要将$.each
函数的内部更改为如下内容:
$.each(data, function(key, value) {
series.name = key;
series.data = {
y: value.property_you_are_interested_in
};
options.series.push(name);
});
…当然,如果您想使用其他形式之一,也很容易:
//First form (array of y values)
var series = {};
series.data = [];
$.each(data, function(key, value) {
series.name = key;
series.data.push(value.property_you_are_interested_in);
});
options.series.push(series);
//Second form (array of x, y values)
var series = {};
series.data = [];
$.each(data, function(key, value) {
series.name = key;
series.data.push([value.X_property_you_are_interested_in, value.Y_property_you_are_interested_in]);
});
options.series.push(series);
