Question

在Amcharts中，条形图中缺少某些类别字段（X轴值）。我有超过200个x轴值。请检查以下代码。

<!-- Styles -->
<style>
#chartdiv {
  width: 100%;
  height: 500px;
}
</style>

    }], 
    "chartCursor": {

        "labelRotation": 90
    }, 
    "export": { 
        "enabled": true 
    } 
}); 
</script> 

<!-- HTML --> 
<div id="chartdiv"></div>

请查看图片以获得更清晰的信息。条215已创建，但不显示所有条形的字段值。

请建议我如何在条形码中获取所有x轴文字。

在"minHorizontalGap": 0中添加"categoryAxis"，如下所示：

"categoryAxis": { 
    "categoryAxis.dashLength":100,
    "categoryAxis.gridPosition": "start",
    "gridPosition": "start",
    "autoGridCount": "true",
    "gridPosition": "start", 
    "autoGridCount": "true",
    "labelRotation": 90,
    "minHorizontalGap": 0
}

默认间隙设置为75，这会导致标签无法被如此大量的标签看到。
