question:

how can I generate pics with chinese characters with local font settings? (ignore environments)

Inizia eseguendo lo snippet Python fornito e verifica come mplfinance e Matplotlib gestiscono il font SimHei configurato. Conferma se il titolo cinese viene renderizzato senza gli avvisi segnalati relativi ai glifi mancanti, trattando il percorso del backend di PyCharm come contesto ambientale da ignorare.
