Nguyên văn bởi vô tình

Cho em hỏi nếu em muốn tên của điểm bự ra như trong hình của thầy Hùng thì làm thế nào ạ?

À, dưới cái begin{scriptsise}, em thêm 1 dòng: " \fontsize{12}{10}\selectfont " là được.

Chẳng hạn như bên dưới:

\definecolor{uququq}{rgb}{0,0,0}
\definecolor{zzttqq}{rgb}{0,0,0}
\definecolor{qqqqff}{rgb}{0,0,0}
