Raylib CSV Scatter Plot

This repository contains a simple C program that uses the raylib library to plot a scatter plot from CSV data. The user can drop a CSV file onto the window, and the program will plot the points from the file.

Structure

• src/main.c: Contains the main program logic.
• data.csv: Sample CSV data file.

Features

• CSV Loading: The program can load points from a CSV file with the below format:

time,x,y,z,a,b

2023-08-09 23:34:20T+09:30,15,150,250,350,450
2023-08-09 23:35:20T+09:30,22,200,300,400,500
2023-08-09 23:36:20T+09:30,15,150,250,350,450
2023-08-09 23:37:20T+09:30,22,200,300,400,500

• Interactive Plotting: Drop a CSV file onto the window to plot the points.
• Scalable Axes: The x and y axes are drawn with a scale to provide context for the plotted points.

How to Run

1. Ensure you have raylib installed.
2. Compile the program using the provided Makefile or using the following clang command:

   clang -o bin/app src/main.c -I/path_to_raylib_include/ -L/path_to_raylib_lib/ -lraylib -framework IOKit -framework Cocoa -framework OpenGL
   

   Replace /path_to_raylib_include/ and /path_to_raylib_lib/ with the appropriate paths to your raylib installation.
3. Run the compiled executable.
4. Drag and drop a CSV file onto the window to visualise the data.

Code Overview

The main components of the code are:

• Point Struct: Represents a 2D point with x and y coordinates.
• LoadCSVData Function: Loads data from a CSV file into a dynamic array of points.
• Main Loop: Handles the raylib window, checks for file drops, and draws the scatter plot and axes.
