High/low stroke coloring in AnyChart applies different stroke colors to the high and low ends of each vertical bar in a HiLo series. This gives a compact, line-based visual signal of range direction without filled areas.
This sample creates a HiLo chart from daily OHLC-style financial data spanning January to April 2018. The high stroke is colored green and the low stroke is colored red, with point markers enabled for precise reading. By-X interactivity mode allows hovering over a date to compare high and low values side by side.
See the Color Management documentation for all configuration options.
