SOLVED: gnuplot vector arrow length and streamlines

neo mendax:

I have already asked about vector fields in here. Now I want to know a bit more about it.

How can I make it so that each arrow has the same fixed length and define the magnitude of the value by color?

And is it still not possible to plot streamlines in gnuplot? If possible, how can I do that?

For now I have this and need to upgrade it.

set term pngcairo
set title 'Navier-Stokes Equation'
set terminal png size 1280,720
set output 'vec.png'
plot 'vec' u 1:2:($3/$5):($4/$5) w vec t 'Vector Field'
