हाय में दिशा पथ का रंग बदलने के लिए कैसे मैं मानचित्र पर काम कर रहा हूं http://gidzior.net/map/v3_animate_marker_directions.html जो प्रारंभ से अंत बिंदु तक रेखा दिखाता है। मैं इस लाइन का रंग बदलना चाहता हूं, क्या कोई मेरी मदद कर सकता है? मैंने सोचा कि इन मूल्यों को बदलने में मदद मिल सकती है, लेकिन इनमें से कोई भी काम नहीं करता है।Google मानचित्र v3
