Histogram problem with boundaries

Q&A
1

If I auto-determine the plot boundaries from the bins (-T) and do not use the central option (-F), histogram will eat the last column:

code:
gmt begin tmp pdf
cat code | gmt histogram -T0.05 -JX4/4 -W1 -BSW -Bxa.1 -Bya5f1
gmt end

data:
0.800
0.800
0.200
0.200
0.400
0.800
0.200

The plot does not show the 0.8-column.
Could it be a float/int-problem because all data is at bin boundaries? Or is it merely a fence-post problem? Or am I thinking wrong?

Thanks for the post - the auto-range detector did not consider the width of bins and sometimes (when a small tick interval) we would fail to set a range that would show all bins (or with -F clipping some bins). A PR has been submitted on GitHub.
