在汇报和统计中经常需要展示各部分占比,手动绘制环形图不仅耗时而且难以调整。环形图生成器能帮您快速将数据转换为高清环形图,只需输入各项目的名称及对应数值,即可自动生成比例准确的环形图,直观呈现数据分布。环形图又称圆环图,是饼图的变体,中心镂空可展示总计信息,适合用于展示百分比、份额等。
输入数值应为正数,不支持负值或零值(除非全为零则无法生成有意义图表)。标签与数值数量需一致,否则会提示错误。生成的环形图基于您输入的数据,不会上传到服务器,所有处理均在浏览器本地完成,保护数据隐私。若数据类别超过10个,建议简化分类以避免图表挤拥。导出图片的清晰度与浏览器窗口大小相关,可放大页面再导出获得更高清图片。
环形图适合展示5~8个类别的占比,类别过多时建议改用条形图。对于强调总体量的场景,可在镂空中心添加总计数值(本工具支持通过标题/副标题实现)。如果希望显示具体数值而非百分比,可以在生成后通过二次编辑添加。常见应用:市场占有率、预算分配、调查问卷结果等。为了确保色彩可辨识,请为相邻类别选择对比度较高的颜色。
