@janhardo this time is worked i can undrestand this code is so better than other, onthing remain, can you do that too? 
at least tell the Ai do that for me change the color of the line both of them are black and take a look see how much is easier

@janhardo watch my file and what i told you use that equation i mentioned

@janhardo your function is wrong in the first when  you use my function without t i told you you have to used and it is used, know i am telling you your function is wrong tell your Ai to use this set up but use my function and line i will upload file
(equ) is shape of of lump and the line is clear is (eq1) and (eq2) is each line have 3 countour which i thing red red must be in eq1 and eq2 be like that set up this it will be done 

2-line-countour.mw

@janhardo if possible give that code which i mention maybe i can ask to other to make simplify , last code is so hard i can involve it the part have proc i removed a lot of part but didn't work, which Ai you use? 

@janhardo  i will do my best but my coding is bad , and just this graph remain in this topic after this a will go to another structure but i have to undrestand how they effect and how they construct and what is relation , i think you use Ai i am true?

@janhardo 

@janhardo  

@janhardo it take time to arange thus function F also, did you remember you found series of this F, in first picture lump are related with trajectory in here not! , also why you take u like that and why just take Re(u)

@janhardo  why you change all of that i did why change the function and whole program , is so pretty but i can't involve it and make move the part is so sensitive , the function changed the line changed the first program  is so better this is good but the parts is not clear

@janhardo maybe you used old function of lump! give me the mw file

@janhardo  this kind are wronge in my file all things set up  we have done  just rotate it by a(1)a(2)b(1)b(2)

@janhardo they did in front of you say I can't they did in all paper watch the picture in mw file i write eq1 and eq2 they two line but how combine this two line

@janhardo How plot like graph d

cant_plot.mw

@janhardo why didn't change function and add two line like i did in last mw file?

@janhardo i don't have idea but maybe you can plotted , i did all part but arange the plot we need more countour like add more than three another contour which for line y[1] 3 and for y[2] 3 contour and they show up in one graph can you do that?
