问题原因 #

对数刻度无法处理非正数（负数和0的对数无数学意义），你的数据中存在负值和0，导致gnuplot生成的LaTeX代码出现数值溢出，触发Number too big和Dimension too large等错误。

解决方法 #

1. 处理数据符号：误差百分比通常关注绝对值，绘图时取数据的绝对值，将plot命令中的using 1:2改为using 1:(abs($2))
2. 调整y轴范围：原y轴范围[0.1,1]未覆盖数据绝对值的全部范围（最大值为13.1），修改为[0.01:20]以包含所有数据
3. 修正图例位置：原图例位置500,-2.750在对数y轴下超出可视区域，调整为500,0.02（可根据实际显示微调）

修改后重新运行gnuplot生成Pic.tex，再编译LaTeX文件即可正常生成图形，避免数值溢出错误。
