Glitch in TRIGRID using grid spacing [message #5526]

Hi,
Up until recently when I used TRIGRID for irregular data gridding I just
let it return the default array size of 51 x 51 elements. Then I tried
to increase the size of the array to the same dimensions as the input
data, which was irregularly spaced on a 61 x 61 grid, by setting the grid
spacing option to [1, 1]. This returned a 61 x 61 array alright but the
contour plot has a distortion that runs from the centre out to the 3
o'clock direction. I checked the numbers on that row of data and they
don't look right compared with the rows above and below. Has anyone
experienced similar problems with trigrid when using the grid spacing
parameter?

Thanks,
Paul
