File Information

Function HISTG ('grouped histogram') adapts Matlab's HIST to cases where data vector includes values from several observed groups, and lets one color-code group membership on the overall histogram. Separate histograms are constructed for all x-groups (each identified by a distinct finite value of a class-assignment variable c), and vertically stacked. HISTG offers display options (x-percentile cut-offs, absolute axis limits, bin size, marker line) implemented in HISTF, linked to below. (Note: when range of x is limited with [pmin, pmax], no adjustment for truncation is made. The cut-offs are meant to exclude 'extreme', low-mass values).

Required Products Statistics and Machine Learning Toolbox
MATLAB release MATLAB 7.2 (R2006a)
MATLAB Search Path
Other requirements HISTG invokes function PRCTILE of Statistics Toolbox, which can be replaced with a user-contributed function.

Would have liked the option to include a legend. But otherwise very good. Thanks.

Very useful. Would be nice if the group vector was allowed to be a cell, like gscatter etc.
