आईओएस कोर-प्लॉट स्क्रॉल कोरप्लॉट संस्करण 1.6 का उपयोग कर

Question

अच्छी तरह से काम नहीं करता है। आईओएस 8.3 चल रहा है।

मैं गुणक लाइनों का प्रतिनिधित्व करने के लिए स्कैटरप्लॉट के साथ कोर-प्लॉट का उपयोग कर रहा हूं। जब मैं स्क्रॉल करता हूं, तो ग्राफ कूदता है और यह ताला लगा देता है। मुझे नहीं पता कि क्या होता है। क्या आप मेरी मदद कर सकते हैं? यहाँ मेरी कोड:

आप अपनी पुस्तक को देखने की सामग्री आकार रीसेट है? यदि नहीं, तो इसे स्कैटरप्लॉट के फ्रेम आकार पर रीसेट करें यदि यह केवल स्क्रॉल व्यू के अंदर दिखाई देता है।
