While a bar chart breaks down categorical data into rectangular bars or columns, a histogram plots data in bins, which group values into specific intervals. {h+ [I:t6VEc&33A[xc~c@W"GGsx QZH w[MWe$o4r*`t: \c,JPLBUm"hv6/37[7["/TY\2HL:9s')kqc_/%}:#1 ,lLc$ plot Stataxplotxy scatter y1var y2var, low 2500gage lwt race smoke ptl ht ui ftv bwt Hosmer-LemeshowP10.
