Speaking Stata: Logarithmic binning and labeling

Stata Journal, 2018, vol. 18, issue 1, 262-286

Abstract: Histograms on logarithmic scale cannot be produced by an option like xscale(log). You need first to transform the variable concerned with a loga- rithm function. That raises small choices: how to select bin start, bin width, and informative axis labels and titles? Problems and solutions are discussed here in detail. In contrast, for logarithmic scales on other graphs, options xscale(log) and yscale(log) may do most of what you want. But there is usually still scope for “nicer” axis labels than are given by default and indeed scope for differing tastes on what “nice” means. This column introduces the niceloglabels command for helping (even automating) label choice. Historical notes and references are sprinkled throughout.
