修完后，在launch模式下导出，下面两个命令随便用一个就好了
Out_Yobs_Ycalc_and_Difference(file)
Outputs the x-axis, Yobs, Ycalc and difference.
[file]: Filename. Can include drive and path.

Out_X_Yobs(file), Out_X_Ycalc(file), Out_X_Difference(file)
Outputs the x-axis, Yobs, Ycalc and difference to files.
[file]: Filename. Can include drive and path.

用导出来的文件作图就好了
