Page history through a feed, stream live updates, or connect HTTP column endpoints. Your host supplies the historical and streaming data.
API reference
Browse public types, method signatures, configuration fields and module-level
contracts for main (0.3 in development), egui/eframe 0.37, with all crate
features available. Rustdoc has its own symbol search: use it for names such as
Chart::add_pane. The guide’s Search finds explanations and tasks.
For the published 0.2.0 crate, which uses egui/eframe 0.33.3, open the separate release API on docs.rs.
Panes share the chart’s time axis and hold series or studies on their own price
scales. Overlays start in the price pane; oscillators can create separate panes.
Use Chart::add_pane
and move_series_to_pane
to place a series. Resize or reorder panes with set_pane_height and move_pane;
PaneOptions
controls separator interaction. Start with a built-in study.
Markers
Section titled “Markers”Attach trade signals or events to a bar series with
Chart::set_markers.
Marker
sets the time, position, shape, colour and text; set_marker_options controls
autoscaling and drawing order. Markers belong to bar series, rather than study
outputs. For missing observations, use whitespace bars.
Extensions
Section titled “Extensions”Custom studiesImplement Indicator or supply a CustomIndicator calculation, with one value per source bar.
Custom series and primitivesDraw host geometry with Primitive and Chart::attach_primitive on a series' pane and scale, or build a series from a study.
Custom drawing toolsRegister a DrawingRenderer under a stable host-owned id before loading saved drawings.
Themes and formattersUse the theme presets, host translations and chart formatters to fit your application.
Attach a renderer with
Chart::attach_primitive,
or implement DrawingRenderer
for a custom drawing tool.
Recipes
Section titled “Recipes”Keep a workspace
Save and load drawings, synchronize charts, and compose the application UI. Accounts and durable storage belong to your application.
For full applications using the public API, browse the runnable examples.
