makeContent.EulerTags: Re-place tags at draw time so resizing the device doesn't...

In eulerr: Area-Proportional Euler and Venn Diagrams

Re-place tags at draw time so resizing the device doesn't clip labels.

Description

The panel viewport is active when makeContent fires, so we can measure each tag's footprint in current native units via grid::convertWidth(grobWidth(...), "native") and call eunoia's place_euler_labels() again. On resize, grid invalidates the tree and makeContent re-runs, so the placement tracks the current device automatically.

Usage

## S3 method for class 'EulerTags'
makeContent(x)

Arguments

x	an EulerTags gTree.

Details

Tags whose measured size is zero (or whose anchor / kind eunoia can't compute) keep the positions they were built with — typically the setup-time placement stored on centers$x / centers$y.

Value

x, with its children repositioned for the current device size.
