提示 (Greetings fromThe On-Line Encyclopedia of Integer Sequences!) <font size="+2">Plot pairs of sequences in the OEIS</font> Sequence 1 Sequence 2 untransformed absolute value log base 10 反双曲正弦 untransformed absolute value log base 10 反双曲正弦 Shift Note: When taking logarithms, sequence values will be adjusted as needed.   Contents of Plot Plot Seq2(n+转移) vs Seq1(n) Plot Seq2(n+转移) vs n and Seq1(n) vs n Plot Seq1(n)/Seq2(n+转移) vs n Note: When plotting the ratio of two sequences, the ratio will be transformed using the choice for Seq1(n). Appearance of Plot Draw points Draw line segments Sample pairs of sequences to plot: Pairwise plots A117154 vs A119560(mathematically obscure but visually interesting - see the link in the latter sequence for more) A119560 vs A40 A4055 vs A40(Suggested by David Wilson) 转移:A108618(n) vs. A108618(n+1), untransformed and without line segments, produces a spiral. (Suggested by Creighton Dement.) Both sequences against n A002330 and A002331，A002365 and A002366，A076340 and A076341, with line segments. (Suggested by Franklin Adams-Watters.) A007305 and A007306(Suggested by David Wilson) Ratios Bernoulli numbers:log(|A27641/A27642|)，log(|A367/A2445|)，A50925/A50932 Convergents to sqrt(2):A1333/A129 1/n!：A12/A142 1/n:A12/A27
