numpy - Python plot values at nodes in meshgrid -

i have from

numpy.meshgrid(xx,yy)

a rectangular grid.

to coordinates (nodes) split 2 lists x , y values:

x = (0.0 , 0.2 , 0.4 , 0.6 , 0.8 , 1.0)*6 y = (0.0 , 0.2 , 0.4 , 0.6 , 0.8 , 1.0)*6

which gives grid 36 points. (think of unit square)

now have solving linear scheme of equation list have size (36,1).

i want plot values (36,1) list @ corresponding nodes in grid.

so first 6 points (36,1) list lies on x-axis (y = 0) , next 6 lies on y = 0.2 , on. have thought how this?

take output array and:

disparray = myarray + (arange(6) * .2)[:,none] plot(x.flatten(), disparray.flatten(), '.')

this should do.

and, of course of study can plot loop.

figure() r in range(myarray.shape[0]): plot(x[0], myarray[r] + 0.2*r, 'k')

this uses x values first row of mesh x values in plot , plots each row of result array myarray @ offsets 0, 0.2, 0.4... black line
