Optional ReadonlychartThe visual's own drawing. Moved inside MAIDR's figure, so it becomes the chart the reader navigates. Omit it for companion mode.
Optional ReadonlyonCalled as the reader moves, with the data points under MAIDR's cursor,
and with null when the reader leaves the chart — focus moves out of the
visual, or the visual's frame loses focus to another part of the report.
Highlight the marks, or build selection ids from the refs and call
selectionManager.select(); clear them on null.
Optional ReadonlylabelThe visible text of companion mode's entry point. Default: the title, or "Accessible chart". Screen readers hear MAIDR's own instruction instead: the entry point is an image to them, named by MAIDR.
Optional ReadonlyemptyWhat the focusable empty state says when the data view holds nothing to navigate — no fields bound, or a filter that leaves no rows. Default "No data to read".
Optional ReadonlyliveApply new data in place while the reader is inside the chart, keeping
their position. On by default, unlike the Tableau binder: a visual's
frame keeps its focused element when the reader moves to a slicer, so
MAIDR cannot tell that they left, and data held back "until they leave"
would be held until they happened to tab out of the visual — the reader
would come back from changing a filter to the unfiltered chart. Pass
false to hold new data until focus leaves the visual itself.
ReadonlychartThe chart the visual draws. See PowerBIChartType.
Optional ReadonlybarHow a multi-series bar or column chart is drawn. Default grouped.
Optional ReadonlytitleChart title announced on entry.
Optional ReadonlysubtitleOptional ReadonlycaptionOptional ReadonlyaxesAxis labels. Default: the display names of the fields bound to each axis — for a pie, the category and measure names.
Optional ReadonlyrolesRole names, when the visual's capabilities use other ones.
Optional ReadonlyidThe figure id. Must be unique on the page; default maidr-powerbi-<n>.
