zoom_to()

Set the zoom window of a chart in a running app, R's GC_zoom_to().

Moves the zoom slider of .zoom() without drawing the chart again from Python. With .events(zoom=True), the chart reports the new window as input.<id>_zoom(), with action "set".

Usage

from geneviewer.shiny import zoom_to

zoom_to(id, range=None, session=None)

Arguments

Argument	Type	Description
id	str	The output id of the chart, as in output_geneviewer.
range	sequence of two numbers or None	The window, as [start, end] in the units of the mode of .zoom(): shares of the clusters ("relative") or base pairs ("absolute"). None shows everything. The range of input.<id>_zoom() can be passed back as it is.
session	shiny.Session, optional	The session; by default the current one.

Errors

Error	When
ValueError	When id or range is not valid.
RuntimeError	Outside a Shiny session.
