|
|
|
|
|
* - 参数：
|
|
|
|
|
* - memberData: 按日期的会员状态数组（每项包含 free/paid/comped 等）
|
|
|
|
|
* - mrrData: 按日期的 MRR 历史数组（每项包含 date/mrr/currency）
|
|
|
|
|
* - dateFrom: 选择范围的起始日期（YYYY-MM-DD 格式）
|
|
|
|
|
* - memberCountTotals: 可选的当前汇总 totals（如来自 meta，用于优先显示最新汇总）
|
|
|
|
|
*
|
|
|
|
|
* 逻辑要点：
|
|
|
|
|
* - 若没有数据，返回一组默认的 0/同向(same) 值，避免上层处理空值判断。
|
|
|
|
|
* - totalMembers 使用 memberCountTotals（如果可用）或 memberData 最后一个来计算。
|
|
|
|
|
* - percentChanges: 只有当时间序列包含 >1 个点时才计算与第一个点的百分比变化。
|
|
|
|
|
* - 对 MRR 的变化判断有特殊策略：
|
|
|
|
|
* - 识别 "from beginning" 范围（例如年初开始或更早），在该场景下若首点不在范围起始，默认首点为 0（YTD 语义）。
|
|
|
|
|
* - 对于最近范围（非 from-beginning），若缺少起点，使用范围前最近的 MRR 值（视为平滑承接）。
|
|
|
|
|
* - 若首点为 0 且当前 MRR>0，按业务逻辑显示 100% 增长。
