Description

I'd like to be able to extend an extra vertical line through the borders of the chart area until the end of the reserved space on the bottom. Might be useful in general to extend both vertical and horizontal line up until the end of the reserved size on each end of the chart.

Contributor guide

Research direction
Investigate the chart rendering code to find where borders are drawn and how to extend lines beyond them, possibly by modifying the `drawBehind` or `drawAbove` callbacks or adjusting the chart's padding and clip behavior.
