Gridded2DSet for a irregular grid / geometry of points
i have a function (x,y) -> (color) and use it as a background for a
diagramm. now i try to transform this background for a diagramm with
logarithmic axisis. that means i need a grid with irregular distances. the
gridded2dset i used had either the wrong length or the wrong dimension or
was useless in an other way. i have no idea how to go on. please help! (may
be with same code?)
an other question is the geometry of the points in visad. do they have to
be squared or are there other forms. and is it possible to center the
points on the coordinates? if i try to pick a point near many others
it could help if the center of the point would be the best place for.
thanks for all.
