plotData

plotData is a simple Java application that reads numerical data from a 2-column CSV file and generates a chart saved as an image (output.png).

How to Run

1. Prepare your data file

Ensure a file named data.csv exists in the same directory.

Example format:

• Time,Velocity
• 1,10
• 2,15
• 3,7
• 4,20

2. Compile the project

Ensure you have Java installed. Open a terminal in the project directory and run:

javac *.java

3. Run the application

java Main

4. View the output

After running successfully, the chart will be saved as:

output.png

Open this file to view the generated chart.

Tips

• Make sure data.csv is in the correct location
• Check file permissions if access is denied
• Ensure your CSV format matches what CsvReader expects

---

Notes

• The output file (output.png) will be overwritten each time the program runs
• Modify filename in Main.java if you want to use a different input file

---

TODO

• read any .csv file not just data.csv
• change output filename to {INPUT_FILENAME_WITHOUT_EXTENSION}_{YYYY.MM.DD HH:MM:SS}.png so the program can be run repeatedly
