據說紫微斗數命盤組合共有二十六萬多個，要學懂每個命盤十分困難，所以先將命盤歸類簡化，再逐步加入更多細節、變化和修改，進而更仔細分析不同命盤，這裡就介紹120種擴展基本盤的分析方法。
斗數命盤可根據主星分佈可分為6個基本盤，再分正反盤可歸類為12基本盤，這是將所有命盤分為12種的基本分析。接下來加入10種干化的影響，將12個基本盤的盤風加以修正微調，形成120個擴展基本盤。
干化是出生年份的天干，決定著不同副矅的安星法，這些為命盤帶來的影響副矅，就包含了四化，擎羊、祿存、陀羅和天魁、天鉞。
四化提供了主星的四種不同變化，令主星的性質更多、更集中、更表面或變異，按不同出生年天干安放，列表如下：
祿存帶來收窄的意味，擎羊則進取具有破壞性，陀羅則有拖延及持續的力量。祿存也按出生年的天干安放，而擎羊則在祿存順時針下一個宮位，陀羅在祿存上一個宮位，所以知道祿存位置，便很容易知道擎羊和陀羅的位置。
天魁、天鉞為對星，為增加實力的副星，同樣按出生年干安星，安星法如下圖：
紫微斗數的學習過程，應由淺入深，先理解12基本盤的基本結構，將人們粗略的分為12種，然後再加入副星雜矅的變化，進一步增加分析不同星矅解讀的能力。但由於120個擴展基本盤數量太多，無法在一篇全部分析，接下來慢慢補充每個盤的介紹，並將連結補充在下方列表：
