Box-and-Whisker Plot Maker

  Sample box-and-whisker plot produced

Inspiration

Constantly needing to look up how to import data into excel properly, when a program could do the same thing instantly from the command line.

What it does

It takes in a data file with a single column of integers and produces a simple box-and-whisker plot, with min, Q1, Q2, Q3, and max labeled.

How I built it

Staring with a data structure for storing the data, one for computing the plot information, and one more to make the plot itself.

Challenges I ran into

Getting proper formulas for where the quartiles should be in the data set, given there are an even number, odd number, or a number divisible by 4. Properly spacing the plot, so it looked appropriate.

Accomplishments that I'm proud of

Getting most of the to-do list accomplished.

What I learned

How to use Java's JFrame to make plots that change based on what data is used.

What's next for Box-and-Whisker Plot Maker

Adding functionality to make histograms (fixed-width and fixed-frequency) and allow for datafiles with multiple columns.
