- [getDataTable](https://chart.syidax.com/docs/methods/getDataTable.md) — Resolves the data table for the current data ( / 134). Waits for the type's load answer and rejects with a ChartLoadError (its `code` = the status) when the type cannot be drawn here: no table is invented for it. A Pro chart type's table comes from its element only (the facade carries no Pro data resolvers).
- [getCSV](https://chart.syidax.com/docs/methods/getCSV.md) — Returns the chart data as a CSV string (UTF-8 BOM, RFC 4180).
- [getSVG](https://chart.syidax.com/docs/methods/getSVG.md) — Returns the chart as standalone SVG markup (canvas families wrap their raster); the drawing overlay rides along as a nested layer, and the brand is the last layer over everything. Keeps its `string | null` contract: null when the type cannot be drawn here (see getDataTable) or there is no surface yet.
- [exportCSV](https://chart.syidax.com/docs/methods/exportCSV.md) — Downloads the chart data as a CSV file (). Data only: no brand. Rejects like getDataTable when the type cannot be drawn.
- [exportSVG](https://chart.syidax.com/docs/methods/exportSVG.md) — Downloads the chart as an SVG file (). Rejects with a ChartLoadError when the type cannot be drawn here.
- [exportPNG](https://chart.syidax.com/docs/methods/exportPNG.md) — Downloads the chart as a PNG file at `exportScale` (). Rejects with a ChartLoadError when the type cannot be drawn here.
- [print](https://chart.syidax.com/docs/methods/print.md) — Prints an inlined snapshot of the chart (Highcharts `printChart`), brand included. The snapshot goes into a hidden frame of this document that prints itself: the former popup (`window.open(…, 'noopener,noreferrer')`) always got `null` back — `noopener` hides the new window from its opener — so nothing was ever printed, and a popup opened after the awaited export would also meet popup blockers. The frame is built with DOM calls only: the chart title becomes the document title and the image's alt text as plain text (never HTML), and no inline script or handler is needed. Rejects with a ChartLoadError when the type cannot be drawn here.
- [setContextMenuEnabled](https://chart.syidax.com/docs/methods/setContextMenuEnabled.md) — Enables or disables the shared right-click context menu at runtime.
- [openContextMenu](https://chart.syidax.com/docs/methods/openContextMenu.md) — Opens the shared context menu at chart-local coordinates, or the chart centre when omitted.

- [getShotOf](https://chart.syidax.com/docs/methods/getShotOf.md) — Wafer map: shot (reticle) coordinate of a lattice cell (`null` on other types).

- [selectDie](https://chart.syidax.com/docs/methods/selectDie.md) — Wafer map: select a die programmatically (`null` off-lattice or on other types).
- [clearDieSelection](https://chart.syidax.com/docs/methods/clearDieSelection.md) — Wafer map: clear the die selection.
- [getSelectedDie](https://chart.syidax.com/docs/methods/getSelectedDie.md) — Wafer map: the current die selection (`null` when none or on other types).
- [appendDie](https://chart.syidax.com/docs/methods/appendDie.md) — Wafer map: stream one probe result in (cell upsert; re-tests emit `binChanged`).
- [updateDie](https://chart.syidax.com/docs/methods/updateDie.md) — Wafer map: patch one die's data (creates the cell when absent).
- [getDieIndex](https://chart.syidax.com/docs/methods/getDieIndex.md) — Wafer map: map index of a notch-frame lattice cell (`null` off-wafer or on other types).
- [getDieByIndex](https://chart.syidax.com/docs/methods/getDieByIndex.md) — Wafer map: die entry addressed by its map index (`null` off-wafer or on other types).
- [getRunningTotal](https://chart.syidax.com/docs/methods/getRunningTotal.md) — The waterfall's running total after its last step (the value a total bar stands to); `undefined` on any other type.
- [getTypeLoadState](https://chart.syidax.com/docs/methods/getTypeLoadState.md) — The chart type's current load answer : status, tag, entitlement state, reason and attempt.
- [whenTypeReady](https://chart.syidax.com/docs/methods/whenTypeReady.md) — Resolves once the chart type's answer is settled — ready, or the reason it cannot be drawn — after a pending license or an import in flight. Never rejects: check `status`.
- [retryTypeLoad](https://chart.syidax.com/docs/methods/retryTypeLoad.md) — Asks for the chart type again (a new attempt), e.g. after `load-failed`; resolves with the settled answer.
- [getEngineStatus](https://chart.syidax.com/docs/methods/getEngineStatus.md) — The engine behind the chart : the element's own getEngineStatus() once the type is drawn; while it cannot be, the facade's answer — `unavailable` with the license code, `module-missing` (not installed or not selected) or `load-failed` (the element's chunk). Null while the type is loading, for an unknown type, and before the element answers.
