我使用库amchart使用插件 dataLoader 生成图表 。但每次图表的开头和结尾都会无缘无故地出现空白的一天。有人已经收到此错误了吗？
-- 编辑 fiddle --
我使用 amchart 中的示例数据创建了一个 fiddle ，您可以找到 here 。我只是将图表类型更改为“折线”，将默认周期更改为“10D”，正如您所看到的，图表右侧仍然有一个空格(如果您更改周期，左侧也有一个空格)。可以删除吗？

最后，
在“categoryAxesSettings”中的示例中:将“startOnAxis”更改为true
"categoryAxesSettings": {
"equalSpacing": true,
"gridColor": "#555",
"gridAlpha": 1,
"startOnAxis" : true, // add this line
},
