Hi list,

I have some files with data stored in columns:

x1 y1 z1

x2 y2 z2

x3 y3 z3

x4 y4 z4

x5 y5 z5

.......

and I need to make a contour plot of this data using matplotlib. The

problem is that contour plot functions usually handle a different kind

of input:

X=[[x1,x2,x3,x4,x5,x6],

[x1,x2,x3,x4,x5,x6],

[x1,x2,x3,x4,x5,x6],...

Y=[[y1,y1,y1,y1,y1,y1],

[y2,y2,y2,y2,y2,y2],

[y3,y3,y3,y3,y3,y3],.....

Z=[[z1,z2,z3,z4,z5,z6],

[z7,z8,zz9,z10,z11,z12],....

I usually load data using 3 lists: x, y and z; I wonder if there is

any function which is able to take these 3 lists and return the right

input for matplotlib functions.

cheers
