histNamebinsxminxmax

histNamebinsxminxmax is a compact label used in data analysis workflows to identify a histogram and its x-axis binning parameters in one token. It is not a universal standard but a descriptive naming convention that can appear in configuration files, logging, or programmatic interfaces.

The token is typically interpreted as four fields: histName, bins, xmin, and xmax. histName is a user-chosen identifier for the histogram. bins indicates the number of bins along the x axis (an integer, though some schemes allow a specific bin edges). xmin and xmax specify the inclusive lower bound and exclusive upper bound of the histogram’s x range, with xmin < xmax. In practice, the exact formatting varies; some systems replace underscores to separate fields (for example histName_bins_xmin_xmax), while others parse by fixed positions or delimiters within the string.

Common usage includes programmatically creating histograms in data analysis pipelines and labeling results in plots or output directories. The same information can often be provided using separate parameters in code; the concatenated form can be convenient for compact configuration or display, but it requires careful parsing to avoid misinterpretation, especially if histName itself contains digits or underscores.

Examples:

- energy_50_0_1 would describe a histogram named energy with 50 bins spanning 0 to 1.

- ptHist_100_0_200 describes a histogram named ptHist with 100 bins from 0 to 200.
