Fixes #3881. + + Added "Pixels Below Min" and "Pixels Above Max" to the CSV output and changed how the data is + outputted. Originally, the CSV output and the GUI histogram would use the DN value in the + middle of a bin to represent that bin. That is, the CSV output used to have a "DN" value that + was the bin's middle pixel DN. This was not intuitive to users. Removed the "DN" value and added "MinInclusive" and "MaxExclusive" to the CSV so that bins are represented by their min/max values. These changes were also reflected in the histrogram creation. The x-axis is now based off of the min value of a bin instead of the middle value. These changes were made alongside changes made to Histogram and cnethist. + diff --git a/isis/src/base/apps/hist/main.cpp b/isis/src/base/apps/hist/main.cpp index 7c3246604a..2b078ea2ee 100644 --- a/isis/src/base/apps/hist/main.cpp +++ b/isis/src/base/apps/hist/main.cpp @@ -23,7 +23,7 @@ void IsisMain() { Cube *icube = p.SetInputCube("FROM");
