AmCharts 每周数据展示

Question

当 "minPeriod" 属性等于 "WW".

时，我在通过 amcharts 显示数据时遇到了一些问题

我的代码笔示例：

var data = [];
var date = new Date();

for (var i = 0; i< 10;i++){
data.push({
    calcDate: moment(new Date()).startOf('day').add(i, 'days').toDate(), 
value: Math.random(100)});}

var chart = AmCharts.makeChart("chartdiv", {
"type": "serial",
"startDuration": 0,
"categoryField": "calcDate",
"theme": "light",
"marginRight": 70,
"autoMarginOffset": 20,
"dataProvider": data,
"graphs": [{
        "type": "column",
        "fillAlphas": 1,
    "balloonText": "[[category]]<br><b><span style='font-size:14px;'>[[value]] C</span></b>",
    "lineColor": "#b6d278",
    "valueField": "value"
}],
"chartCursor": {
    "cursorAlpha": 0.1,
    "cursorColor": "#000000",
},
"categoryAxis": {
    "minPeriod": "DD",
    "parseDates": true,
    "minorGridEnabled": true
},
"export": {
    "enabled": true
}});

Days example (how it must look)

var data = [];
var date = new Date();

for (var i = 0; i< 10;i++){
data.push({
    calcDate: moment(new Date()).startOf('day').add(7*i, 'days').toDate(), 
value: Math.random(100)});}

var chart = AmCharts.makeChart("chartdiv", {
"type": "serial",
"startDuration": 0,
"categoryField": "calcDate",
"theme": "light",
"marginRight": 70,
"autoMarginOffset": 20,
"dataProvider": data,
"graphs": [{
        "type": "column",
        "fillAlphas": 1,
    "balloonText": "[[category]]<br><b><span style='font-size:14px;'>[[value]] C</span></b>",
    "lineColor": "#b6d278",
    "valueField": "value"
}],
"chartCursor": {
    "cursorAlpha": 0.1,
    "cursorColor": "#000000",
},
"categoryAxis": {
    "minPeriod": "WW",
    "parseDates": true,
    "minorGridEnabled": true
},
"export": {
    "enabled": true
}
});

Week example (broken).

如您所见，所有最后一个 link 的标签都向左对齐，这使我的图表非常难看。我认为它的发生是因为实际值与 categoryAxis 预期值之间的脱节。也许有属性可以修复它，但我找不到它。

如果你遇到过同样的问题并对我有什么建议，请帮忙。

Answer 1

您可以在 categoryAxis 中将 centerLabels 设置为 true 以强制标签居中。
