我是dojo图表的新手。我正在尝试使用dojo创建堆积柱形图。我试图使用dojo图表显示带有折线图的条形图。显示出来。但是我的问题是如何编写来自我的数据库的x轴标签名称。我想在X轴上命名每个条形码的名称。我的实际价值来自数据库。我从所有堆栈溢出建议,dojo指南和其他人搜索,但我找不到任何正确的解决方案。所以我请求你帮我,我的代码是错误的。所以在这里我可以纠正我的未来。
这是我的代码 index.php
<?php
include "connection.php";
$array = array();
$array1 = array();
$array2 =array();
$query1 = "SELECT name,rate1,rate2 FROM TEST";
$result = mysql_query($query1) or die ('Could not find Projects');
while ($rows = mysql_fetch_array($result)){
$array1[]=$rows['name'];
$array1[]=$rows['rate1'];
$array2[]=$rows['rate2'];
}
print_r($array1);
print_r (json_encode($array1,JSON_NUMERIC_CHECK));
print_r (json_encode($array2,JSON_NUMERIC_CHECK));

这是我为堆积柱形图编写的代码。所以建议我如何在我的数据库中写出x轴的标签名称。
答案 0 :(得分:1)
向x轴添加标签:
以下是一些例子:
对整个轴使用一个标签的title属性。
chart.addAxis("x", {
min: 0, max: 100,
fontColor: "blue",
vertical: true,
fixLower: "major", fixUpper: "major",
title: "X axis title",
titleFont: "bold bold bold 12pt Arial,sans-serif",
titleOrientation: "axis"
});
对于x轴上每个刻度线上的标签:
var xAxisLabels = [{text: "Today",value: 1},{text: "-1",value: 2},{text: "-2",value: 3},{text: "-3",value: 4},{text: "-4",value: 5},{text: "-5",value: 6},{text: "-6",value: 7},{text: "WK-1",value: 8},{text: "WK-2",value: 9},{text: "WK-3",value: 10},{text: "WK-4",value: 11}];
chart.addAxis("x", {
labels: xAxisLabels,
fontColor: "blue",
majorTicks:true,
majorTickStep:1,
minorTicks:false,
max: 11
});
不确定数据库部分
