graphr

Introduction

graphr is a small language written to create basic mathematical graphs. It is an interpreted language written in python and essentially wraps the matplotlib library using a simple syntax. Heavily inspired by vmem!

Installation

Firstly install matplotlib and numpy

pip install matplotlib numpy

Then clone the repo

git clone https://github.com/swishyy/graphr.git your-project-name

Then run the interpreter and pass a .graphr file with it

cd your-project-name
python interepreter.py file.grapr

Language

$ - Allows for comments.

OPTIONS

TOOLBAR HIDE/SHOW - Hide or show the toolbar when the graph is rendered. Ommiting this command shows the toolbar by default.

WARNINGS HIDE/SHOW - Hide or show warnings in the console when the graph is rendered. Ommiting this command shows the commands by default.

TITLE

e.g. TITLE This is a title - Sets the title of the graph.

EQUATION

e.g. EQUATION x^2 5 - Creates the equation for the graph. Each term must have a space between it and must be in terms of x only.

RANGE

e.g. RANGE -5 5 - Sets the boundaries for the x-axis on the graph.

COLOUR

e.g. COLOUR blue - Set the colour of the line. If a colour is not picked, one will be randomly assigned.

SCREENSHOT

e.g. SCREENSHOT graph - Screenshots the graph and saves it with the filename specified.

SHOW

e.g. SHOW - Simply displays the graph, without this command the graph would not be displayed.
