plot in hexagonal lattice

Show all headers | View raw

Hello!



I would like to plot data-s in a hexagonal lattice. I have a .dat file
in which the 1st and 2nd column are the X and Y coordinates of the
hexagon's centers, and the other columns hold the data, what I want to
plot in the lattice.

I managed only to plot the datas with pm3d, but I don't know, how to
plot the lattice grids, and how to plot hexagons. I plotted the datas
by circles, and I increased the size of it, but it's not the best.
So I would like to get something like the lattice map on the left part
of the picture: http://www.kfki.hu/~aekihp/arlhome/images/verona1.gif

For the lattice I guess I should use a loop and set object polygon,
because from the center of a hexagon ! can evaluate the points of the
hexagon (and I know the lattice pitch), but I don't know how to read
in every step only one X and Y value from my data file, and how to
assign the value of the data (power in my case) to this hexagon.


Thanks for your help!



Best regards,
