Step Four. if TRUE, the histogram graphic is a representation of frequencies, the counts component of the result; if FALSE, probability densities, component density, are plotted (so that the histogram has a total area of one). Histogram divide the continues variable into groups (x-axis) and gives the frequency (y-axis) in each group. Note that traces on the same subplot, and with the same barmode ("stack", "relative", "group") are forced into the same bingroup, however traces with barmode = "overlay" and on different axes (of the same axis type) can have compatible bin settings.
