Installation

This guide follows main (0.3 in development). Use Rust 1.95 or newer and egui/eframe 0.37 so both dependencies share the same egui types.

Documentation	Dependency	egui / eframe
main API (rustdoc) · 0.3 in development	Git, branch main	0.37
Published 0.2.0 API	egui-charts = "0.2.0"	0.33.3

1. Create your application.

   cargo new my-chart
   cd my-chart

2. Choose your dependencies.

   Use the widget alone for a chart, the default features for a larger interface, or the headless engine for data processing without egui.

   Chart widget

   Cargo.toml

   [dependencies]
   egui-charts = { git = "https://github.com/userFRM/egui-charts", branch = "main", default-features = false, features = ["widget"] }
   eframe = "0.37"
   chrono = "0.4"

   Application UI

   Cargo.toml

   [dependencies]
   egui-charts = { git = "https://github.com/userFRM/egui-charts", branch = "main" }
   eframe = "0.37"
   chrono = "0.4"

   Headless engine

   Cargo.toml

   [dependencies]
   egui-charts = { git = "https://github.com/userFRM/egui-charts", branch = "main", default-features = false }
   chrono = "0.4"

3. Check the setup.

   cargo check

   Continue with your first chart to display bars in a native window.

Using a published release?

For published 0.2.0, use egui-charts = "0.2.0" and egui/eframe 0.33.3 with the release documentation. The examples and feature table on this site describe main (0.3 in development).

Enable what your application uses

Feature	What it enables
widget	The egui chart, configuration and theme system
studies	Built-in studies and IndicatorFactory; also works headlessly
alert-engine	services::AlertEngine, which evaluates alerts on the bars the host feeds it; also works headlessly
detectors	services::OrderFlowDetectors, which finds order-flow events in the trades and depth the host feeds it; also works headlessly
strategies	strategies::Backtest, which runs a strategies::Strategy over bars and returns a StrategyReport; also works headlessly
http	data::http::HttpDatafeed, HTTP column history, symbol search and live bar refresh from your server; also works headlessly
drawings	Drawing tools, interaction, undo and persistence; enables widget
icons	Embedded SVG icons; enables widget
csv	CSV import and export for bars, strategy reports and chart data
png-export	PNG image export and image textures in SVG export; enables widget
ui	Toolbars, panels, dialogs, ui_kit and extension helpers; enables icons, studies, drawings, csv and png-export
locales	Localized month and weekday names and AM/PM markers
timezones	IANA zones and daylight-saving rules
serde	Serialization for Theme

The defaults are ui, locales, timezones, csv and png-export. Omit default-features = false and the explicit feature list for that setup. Add studies or drawings to the widget-only list for those capabilities without the full application UI. Without default features, add csv or png-export for CSV or PNG methods. With icons alone, the chart installs only its embedded icon loader.

With default-features = false and no features, the headless engine provides models, data contracts, scales, services and the indicator trait layer without egui.

Native and browser hosts

The widget runs in an egui host. The first chart uses eframe. The repository’s demo shows an eframe WebAssembly app built with Trunk. Host windowing, event loops, network runtimes and browser startup remain application concerns.
