Contour
The data from which contour lines are computed is set in z.
Data in z must be a {2D array} of numbers. Say that z has N rows and M columns, then by
default, these N rows correspond to N y coordinates (set in y or auto-generated) and the M
columns correspond to M x coordinates (set in x or auto-generated). By setting transpose to
true, the above behavior is flipped.

To access the tracemetavalues in an attribute in the same trace, simply use%{meta[i]}whereiis the index or key of themetaitem in question. To access tracemetain layout attributes, use%{data[n[.meta[i]}whereiis the index or key of themetaandnis the trace index. -

public var transforms: [Transform] -
Controls persistence of some user-driven changes to the trace:
constraintrangeinparcoordstraces, as well as someeditable: truemodifications such asnameandcolorbar.title.Defaults to
layout.uirevision. Note that other user-driven trace attribute changes are controlled bylayoutattributes:trace.visibleis controlled bylayout.legend.uirevision,selectedpointsis 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 nouidis provided. So if your app can add/remove traces before the end of thedataarray, such that the same trace has a different index, you can still preserve user-driven changes if you give each trace auidthat stays with it as it moves.Declaration
