Articles on charts and data visualization in Unity: line and pie chart tutorials, real-time graph performance, Swift Charts conventions, accessibility and 3D charts.
November 11, 2026Every chart type in Chart Guru, from sparklines to 3D
A guided tour of the 28 chart types in Chart Guru for Unity, grouped by the job they do, with when to use each, what composed charts add, and how compatible 2D charts lift into 3D.
November 11, 2026Swift Charts to Unity C#: API cheat sheet
A side-by-side map from Swift Charts to the Chart Guru C# API for Unity, with honest notes on partial rows and the naming rule that turns lower camel case into PascalCase.
November 11, 2026Why Chart Guru follows Swift Charts conventions
Ad-hoc chart APIs leave categories, series and styling to you. Chart Guru adopts the grammar of Apple's Swift Charts instead. What that gives people who never wrote Swift, what Swift developers get, how it extends to 3D, and where parity stops.
November 9, 2026Is Unity good for data visualization?
Unity is the right tool when data lives in a 3D context, changes in real time or ships inside a cross-platform app. For reports, web dashboards and heavy tabular analysis, other tools fit better. What charts in Unity need, and where Chart Guru helps.
November 7, 2026Real-time graphs in Unity without GC spikes
Texture redraws, per-point objects and per-frame allocations make live graphs stutter. How Chart Guru for Unity streams data through a thread-safe ring buffer and in-place updates, what its performance guidance recommends, and what a 35,136-point lesson shows.
November 3, 2026How to make a line graph in Unity
Unity ships no line chart control. Four ways to draw one, from a world-space LineRenderer to a chart library with axes, tooltips and live data, with code for each and an honest look at when hand-rolled code is enough.
November 2, 2026How to make a pie chart in Unity
Unity has no pie chart control. Three ways to draw one yourself, with code for start angles, donuts and clickable slices, and what Chart Guru for Unity adds: leader-line labels, angle selection, concentric rings and mini donuts.
October 8, 2026Learn Unity charts with real data: the 27 lessons
How the Chart Guru examples teach charts in Unity: tracks from a showcase to production apps, credited public datasets with their licenses, and why real data exposes layout problems that tidy demo numbers hide.
September 15, 2026Accessible charts in Unity
Accessibility with Chart Guru for Unity: color choices that survive color vision deficiency, descriptions and per-mark labels, Unity 6 screen reader support, audio graphs you can hear, and semantic CSV and JSON export.
July 5, 2026Porting Swift Charts to Unity: The Making of Chart Guru
The making of Chart Guru: why charts turned out to be mostly layout and API design, how pasted Swift becomes PascalCase C#, and how parity tracking, visual verification, SDF shaders and texture output made the port credible.These articles answer the questions that come up when a Unity project needs real charts: how to draw a line graph or a pie chart with Unity’s own tools, how to stream live data without garbage collection spikes, why Chart Guru follows Apple’s Swift Charts, and when Unity is the right place for data visualization at all. The tutorials show the hand-rolled approaches first, with working code, and say where they stop, so you can decide whether a chart library is worth it for your project.
Start with a tutorial
- How to make a line graph in Unity compares a world-space LineRenderer, a custom UI mesh, UI Toolkit’s Painter2D and Chart Guru, with code for each.
- How to make a pie chart in Unity covers filled Images, Painter2D arcs, a custom mesh and clickable donut slices.
- Real-time graphs in Unity without GC spikes explains why live graphs stutter and how ring buffers and in-place updates avoid it.
- Learning charts with real data walks through the sample lessons built on public weather, energy, penguin and chess records.
Swift Charts in Unity
- Why Chart Guru follows Swift Charts conventions explains the design choice, what it gives you with or without Swift experience, and where parity stops.
- Porting Swift Charts to Unity: The Making of Chart Guru tells how the tool was built.
- Swift Charts to Unity C#: API cheat sheet puts Swift Charts code next to its C# equivalent.
- Swift Charts 3D in Unity covers Chart3D, surface plots and poses with the included Chart Guru 3D module.
Choosing and designing charts
- Is Unity good for data visualization? is an honest look at where a game engine fits and where BI tools, web chart libraries or notebooks are the better choice.
- Chart types from sparklines to 3D helps you pick a chart, from label-free sparklines and mini donuts to multi-series 3D charts.
- Accessible charts in Unity covers chart descriptions, screen reader navigation and audio graphs.
