Graph2D add-on for Godot 3.x

This plugin is no longer maintained for version 3 of Godot. Link to the plugin for Godot version 4

Graph 2D is an addon able to display curves in your user interface in a very simple way.

This repository contains the add-on and examples.

Features

• Plot several curves on the same graph.
• Supports curve thickness and color.
• Customizable chart axes (axis label and grid).
• Real-time plotting.
• Works with both the GLES3 and GLES2 renderers.
• Works on desktop platforms and HTML5 (others target were not tested).

Usage

Simple plot

• Create a new scene with a Control type as root node.
  • Attach a script to your root node.
• Add a Graph2D node as a child of the root node.
• To create a new curve, call the method Graph2D.add_curve() from your script. The arguments are in order the name of the curve, its color and finally the thickness of the line.
  • Note: This method will return an identifier (integer) which will then be used to reference the curve and update its points.
• There are two ways to draw a curve:
  • To draw a curve point by point (real-time), you must use the method Graph2D.add_point(). The arguments are in order the curve identifier and the coordinates of the point (Vector2)
  • To draw a curve from a set of points, use the method Graph2D.add_points(). The arguments are in order the curve identifier and a list of points of type PoolVector2Array.
