Simple little tool which does what it says on the tin, it plots stuff. If you have a program which writes out lines of numbers and you want to draw these values in a nice plot then this is the tool for you! The tool will read from standard input and write out a nice plot scrolling left to right. The plot is drawn using the Unicode Braille characters, and each column of values is given a colour chosen from your X resources (your terminal colours). Values in the input can be separated by either whitespace, a comma, or both. The plot also scales to fill your entire terminal, and shows you the lowest and highest value of your data.
The above image was gotten from running a program which received data from an
Arduino reading some analog data. The program running on the Arduino writes out
four values along with the numbers 100,-100 to clamp the graph.
