Histogram

Histogram is a tiny utility that extrapolates numerical data from plain text documents (TXT format) in order to create histograms. It mainly caters to people who work with math, like students.
Installation is not required, which makes Histogram portable. In other words, you can drop the executable file in any location on the hard disk and just click it to run.
Alternatively, you can save Histogram to a USB flash disk or similar storage unit, in order to run it on any machine seamlessly.
Note that the device must not be write-protected, since files are created in the same location by the tool (this option cannot be changed).
An important factor to take into account is that the Windows registry does not get updated with new entries, and leftover files are not kept on the HDD after removing the utility.
Histogram is packed in a user-friendly interface made from a single window, where you can point out a plain text file using the file browser (drag and drop is not supported).
The histogram is immediately evaluated and displayed in the main panel, where you may view various information, such as peak, minimum and maximum value, mean and median. At the same time, the tool delivers a TXT document in the same directory, containing the histogram value coordinates.
The application carries out a task rapidly while using a very low quantity of CPU and RAM. We have not come across any issues throughout our evaluation, since it did not freeze, crash or display error notifications. Although it has not been updated for pretty long while, Histogram smoothly integrates into newer operating systems.
