Unity3D Function Graph Plotter

A lightweight solution for plotting function graphs in Unity3D using UI components.

Features

• Dynamic point plotting on a 2D graph
• Configurable axis dimensions and step counts
• Support for negative axis values
• TextMeshPro integration for axis labels
• Grid lines for visual reference
• Easy integration via prefab

Requirements

• Unity 2020.3 LTS or newer
• TextMeshPro package
• UnityEngine.UI.Extensions (included)

Installation

1. Download the latest release
2. Import the package into your Unity project
3. Drag GraphController.prefab from Assets/theGrahCreator/ into your scene

Configuration

Parameter	Description
Axis Length X/Y	Total length of each axis in units
Steps X/Y	Number of divisions on each axis
Origin X/Y	Starting coordinate offset
Point Prefab	Visual representation of plotted points
Line Renderer	UILineRenderer for connecting points

Usage

Basic Point Plotting

public GraphCreator graph;

void PlotFunction()
{
    for (float x = 0; x <= 10; x += 0.5f)
    {
        graph.InputX = x;
        graph.InputY = Mathf.Sin(x) * 5;
        graph.AddPoint();
    }
}

Input Controller

The GraphCreatorInputController component provides UI bindings:

• AddPoint() — plots a point from input fields
• ClearGraph() — removes all points
• DeleteLastPoint() — removes the most recent point
