请稍微上学。 我有一个工作图表，我需要稍微改变一下。 我的数据有四个字段omlPartgroup，xmonth，xyear和QTY 我希望我的图表显示每个omlpartgroup，然后显示该组中的月份和年份，因此每个partgroup将有12个条形，标签将是具有年和月子组的部分组。
我的代码
window.jQuery(document).ready(function(){
window.jQuery.ajax({
url:"http://localhost/html5/data.php",
method:"GET",
success: function(data){
console.log(data)
var omlPartgroupid =[];
var xyear =[];
var xmonth =[];
var QTY=[];
for(var i in data){
omlPartgroupid.push("PartGroup"+ data[i].omlPartgroupid);
xyear.push(data[i].xyear);
xmonth.push(data[i].xmonth);
QTY.push(data[i].QTY);
}
var chartdata ={
labels:xmonth,
datasets :[
{
backgroundColor: 'rgba(200,200,200,0.75)',
borderColor: 'rgba(200,200,200,0.75)',
hoverBackground: 'rgba(200,200,200,1)',
hoverBorderColor: 'rgba(200,200,200,1)',
data:QTY
}
]
};
var ctx=$("#mycanvas");
var barGraph =new Chart(ctx,{
type: 'bar',
data: chartdata
});
},
error: function(data){
console.log(data);
}
}）; }）;

这里引用： https://github.com/chartjs/Chart.js/issues/2138
它的大部分是创建第二轴。我在这里省略了一些设置，但你可以在下面找到一个JS小提琴：
options: {
scales: {
xAxes:[ {
id: 'time',
type: 'category',
ticks: {
callback: function(label) {
var labelArray = label.split("|");
return labelArray[0] + "/" + labelArray[1];
}
}
},
{
id: 'partGroup',
type: 'category',
gridLines: {
drawOnChartArea: false // only want the grid lines for one axis to show up
},
ticks: {
callback: function(label) {
var labelArray = label.split("|");
return labelArray[0] === "10" && labelArray[1] == "2015" ? labelArray[2] : "";
}
}
}
]
}
}
