Detailed Description

Applies the active theme's palette to a QCustomPlot.

QCustomPlot defaults to a white background with black axes, which is unreadable in dark themes. This helper recolors the background, axes, grids, legend and titles from the theme tokens and keeps them current across theme switches.
