我正在制作关于一天吃的水果的图表,这在下面的例子中正常工作。
var chart = AmCharts.makeChart("chartdiv", {

日期05-09-2018和07-09-2018数据不在dataprovider
字段中,因此我希望它自动填充到图表中。
您当前有一个常规的类别轴,它将日期视为字符串(类别)。
如果你想要一个真实的日期比例,你需要通过在parseDates: true
中设置categoryAxis
使它成为一个基于日期的类别轴。
但这还不够。
由于您的日期为非标准日期格式,因此您需要指示amCharts如何解析它们。这就是dataDateFormat
设置的地方:
dataDateFormat: "DD/MM/YYYY"
最后,标签遵循基于日期的轴上的不同规则。因此,我们需要对代码进行一些调整,以便显示所有代码:
"categoryAxis": {
// ...
"autoGridCount": false,
"gridCount": 20
},
这是你的图表:

"type": "serial",
"hideCredits": true,
"fixedColumnWidth": '10px',
