It's caller's duty to ensure input is valid.
Why we need visual range for histograms? Miss aligned buckets between steps might miss-lead users about the
trend of a tensor. Because for given tensor, if you have thinner buckets, count of every bucket might get
low, however, if you have thicker buckets, count of every bucket might get high. If there are the above two
kinds of histogram in one graph, user might think the histogram with thicker buckets has more values. This is
miss-leading. So we need to unify buckets across steps. Visual range for histogram is a technology for unifying
buckets.
Args:
max_val (float): Max value for visual histogram.
min_val (float): Min value for visual histogram.
