की संपत्ति 'लेबल' नहीं पढ़ सकता है, मैं बस सीख रहा हूं कि chart.js कैसे काम करता है इसलिए मैंने चार्ट.जेएस एपीआई पेज से सीधे उदाहरण कोड का उपयोग किया है और यह काम नहीं कर रहा है। मैं स्क्रिप्ट टैग में निम्न कोड रखता हूं और मुझे "अपरिभाषित" त्रुटि का "संपत्ति नहीं पढ़ा जा सकता है" लेबल मिलता है। सुनिश्चित नहीं है कि इस त्रुटि का अर्थ क्या हैअपरिभाषित
