Configuration

Variable	Required	Secret	Description
MATPLOTLIBNET_MCP_OUTPUT_ROOT	—	—	The only directory save_chart may write under. Defaults to the system temp directory.
MATPLOTLIBNET_FONTS	—	—	Font files (.ttf, .otf) and directories of them, separated by ';', registered at startup so a chart can use a script the bundled font lacks (Devanagari, Thai, Chinese). Arabic and Hebrew work without it.
