# Showcase

The flagship tour of `XWUIChartStepLine`, tracking a feature rollout where the exposure percentage holds steady and then jumps when the team widens the gate. It covers the four block presets, the sm / md / lg canvas scale, the axis furniture toggles, stroke styling, and vertex markers with per series overrides beside the loading skeleton.

It closes on a real world rollout tracking board with grid values, a percentage label at every gate change and hover tooltips.
