Multi Graph

Overview

• Name: Multi Graph
• Category: repeat_instant
• File: lua/ge/extensions/flowgraph/nodes/debug/drawGraph.lua
• Pattern: Class-based (C = {}, returns _flowgraph_createNode(C))

Description

Draws multiple data lines in the same graph within the flowgraph editor. Supports a configurable number of input value pins, each plotted as a separate colored line using rainbow coloring. Graph auto-scales to data range.

Pin Schema

Dynamic Input Pins

Pins are created dynamically based on the count data property:

Properties

Behavior

• work() reads all connected number input pins and appends values to rolling data buffers (max 400 samples). Auto-scales min/max to data range.
• drawMiddle() manages dynamic pin count and renders the multi-line plot via im.PlotMultiLines() in a 400×300 area.
• updatePins() adds/removes input pins to match the configured count and resets graph data.
• resetGraphData() rebuilds labels, rainbow colors, and data buffers from connected pins.
• Graph data uses FIFO buffers - oldest samples are dropped when the 400-sample limit is reached.

Key APIs Used

• im.PlotMultiLines() - multi-line plot rendering
• rainbowColor() - generates distinct colors per line
