Controls persistence of some user-driven changes to the trace:
constraintrange
inparcoords
traces, as well as someeditable: true
modifications such asname
andcolorbar.title
.Defaults to
layout.uirevision
. Note that other user-driven trace attribute changes are controlled bylayout
attributes:trace.visible
is controlled bylayout.legend.uirevision
,selectedpoints
is controlled bylayout.selectionrevision
, andcolorbar.(x|y)
(accessible withconfig: {editable: true}
) is controlled bylayout.editrevision
. Trace changes are tracked byuid
, which only falls back on trace index if nouid
is provided. So if your app can add/remove traces before the end of thedata
array, such that the same trace has a different index, you can still preserve user-driven changes if you give each trace auid
that stays with it as it moves.Declaration

Note that this will override
hoverinfo
. Variables are inserted using %{variable}, for example “y: %{y}”. Numbers are formatted using d3-format’s syntax %{variable:d3-format}, for example “Price: %{y:$.2f}”. https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#d3_format for details on the formatting syntax. Dates are formatted using d3-time-format’s syntax %{variable|d3-time-format}, for example “Day: %{2019-01-01|%A}”. https://github.com/d3/d3-time-format#locale_format for details on the date formatting syntax. The variables available inhovertemplate
