Method regular

include/boost/histogram/axis/types.hpp:129–142

Construct axis with n bins over real range [lower, upper). * * \param n number of bins. * \param lower low edge of first bin. * \param upper high edge of last bin. * \param label description of the axis. * \param uoflow whether to add under-/overflow bins. * \param trans arguments passed to the transform. */
