Can grdimage plot gridded data where the latitudinal bands are unequally spaced? I am thinking particularly of the case where the grid was defined to facilitate integrations using Gauss-Legendre quadrature.
Now, if I have a netcdf grid with unevenly spaced latitude bands, gridimage will plot it. However, if you use grdinfo on the file, it provides a single latitudinal spacing. So either grdinfo is providing misleading information, or grdimage is ignoring the values of the latitudes and assuming that they are equally spaced.
