Re: [Matplotlib-users] creating mesh data from xyz data

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
