问题描述
我对所有这些东西都很新,这可能是一个简单的解决方案,但我无法弄明白。我按照ZingChart的mysql教程,我能够看到我创建的栏,但我想要一个饼图。
< ; div class =row>
< div class =col-lg-12>
< div class =panel panel-default>
< div class =panel-heading>
< h3 class =panel-title>< i class =fa fa-long-arrow-right fa-fw>< / i>饼图< / h3>
< / div>
<?php
$ sqlpie =SELECT Naam,Voorraad FROM product WHERE Voorraad!= 0;
$ data = mysqli_query($ con,$ sqlpie);
?>
< script>
var myData = [<?php
while($ info = mysqli_fetch_array($ data))
echo $ info ['Voorraad']。','; / *我们使用连接运算符'。'在每个数据值后添加逗号分隔符。 * /
?>];
<?php
$ data = mysqli_query($ con,SELECT * FROM Product WHERE Voorraad!= 0);
?>
var myLabels = [<?php
while($ info = mysqli_fetch_array($ data))
echo''。$ info ['Naam']。','; / *这里使用连接运算符'。'来从我们的数据库名称创建字符串值。 * /
?>];
< / script>
< script>
window.onload = function(){
zingchart.render({
id:pieChart,
宽度:100%,
身高:400,
数据:{
类型:bar,
scale-x:{
labels:myLabels
},
系列:[
{
值:myData
}
]
}
});
};
< / script>
< div class =panel-body>
< div id =pieChart>< / div>
< / div>
< / div>
< / div>
< / div>
我想使用具有此格式的Pie
type:pie3d,
系列:[
{
text:Apples,
值:[5]
},
{
text:Oranges,
values:[8]
},
{
text:Bananas,
values:[22]
},
{
text:Grapes,
值:[16]
},
{
text:Cherries,
values:[12]
}
]
任何人都可以帮助我吗?
如果您能够获得条形图,那么您的myData JavaScript变量可能如下所示:
myData = [98,12,36,76];
饼图中的每个饼图切片都需要系列中的自己的对象
,带有 values
属性,该属性采用单个值数组。因此,如果你的myData数组中有四个值,你可以这样做:
var myData = [98,12, 36,76];
window.onload = function(){
zingchart.render({
id:pieChart,
宽度:100%,
高度:400,
数据:{
类型:馅饼,
系列:[
{
值:[myData [0] ]
},
{
值:[myData [1]]
},
{
值:[myData [2] ]
},
{
值:[myData [3]]
}
]
}
});
};

I'm pretty new with all this stuff and it may be an easy solution but i can't figure it out. I followed the mysql tutorial for ZingChart and i am able to see my bar i created, but i want a pie chart.
<div class="row">
<div class="col-lg-12">
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title"><i class="fa fa-long-arrow-right fa-fw"></i> Pie Chart</h3>
</div>
<?php
$sqlpie = "SELECT Naam,Voorraad FROM product WHERE Voorraad != 0";
$data = mysqli_query($con, $sqlpie);
?>
<script>
var myData=[<?php
while($info=mysqli_fetch_array($data))
echo $info['Voorraad'].','; /* We use the concatenation operator '.' to add comma delimiters after each data value. */
?>];
<?php
$data=mysqli_query($con,"SELECT * FROM Product WHERE Voorraad !=0");
?>
var myLabels=[<?php
while($info=mysqli_fetch_array($data))
echo '"'.$info['Naam'].'",'; /* The concatenation operator '.' is used here to create string values from our database names. */
?>];
</script>
<script>
window.onload=function(){
zingchart.render({
id:"pieChart",
width:"100%",
height:400,
data:{
"type":"bar",
"scale-x":{
"labels":myLabels
},
"series":[
{
"values":myData
}
]
}
});
};
</script>
<div class="panel-body">
<div id="pieChart"></div>
</div>
</div>
</div>
</div>
I want to use the Pie which has this format
"type":"pie3d",
"series":[
{
"text":"Apples",
"values":[5]
},
{
"text":"Oranges",
"values":[8]
},
{
"text":"Bananas",
"values":[22]
},
{
"text":"Grapes",
"values":[16]
},
{
"text":"Cherries",
"values":[12]
}
]
Can anybody help me?
If you were able to get a bar chart, then your myData JavaScript variable probably looks something like this:
myData = [98,12,36,76];
Each pie slice in a pie chart requires its own object within series
, with a values
attribute that takes a single value array. So if you have four values in your myData array, you could do something like this:
var myData = [98,12,36,76];
window.onload=function(){
zingchart.render({
id:"pieChart",
width:"100%",
height:400,
data:{
"type":"pie",
"series":[
{
"values": [ myData[0] ]
},
{
"values": [ myData[1] ]
},
{
"values": [ myData[2] ]
},
{
"values": [ myData[3] ]
}
]
}
});
};
I'm on the ZingChart team, so let me know I can do anything else to help!
