GraphCalc

About

I consider Desmos funni, so I decided to bring a similar graphing calculator to the terminal! I originally didn't want to bother with pyinstaller, so I didn't even use regex and instead coded parsing logic myself. The program takes in a math function (currently limited in operator support, i plan on adding more math functions later) and samples its value at multiple points. The values are then saved as a .csv and the program renders them with a bar graph

Options

• --function basic mathematic expression including x. the default (for quick testing) is x*x/4.
• --x-offset positive integer, moves the "frame of sampling"
• --x-range range over which the program should sample, default is 8
• --sample number of samples to use, default is 16
• --file file for csv output, default is function.csv Run options:
• --run, invokes termgraph(.py) after outputting the csv values
• --x-space space available for x axis in terminal, default is 86 to support small terminals, 126 and 168 work well.
• --label provides termgraph with x axis labels for each sample

Installation

Pyinstaller Download both termgraph and termgraph-calc from the pybuilds folder and place them in the same folder.

Windows Run pip install argparse Download both termgraph.py and termgraph-calc.py from the root folder and place them in the same folder.

Linux/macOS Download both termgraph.py and termgraph-calc.py from the root folder and place them into a folder of your choice. In that folder, run

python3 -m venv .venv
source .venv/bin/activate
pip install argparse

To start the program in the venv, run

source .venv/bin/activate
python3 termgraph-calc.py
