I'm plotting satellite data taken from an HDF5 file. The following are the parameters
latitude(51x2429) -> lat
longitude(51x2429) -> lon
longwave(51x2429) -> long
I'm using the following code
shading interp
I get this image
This is what I want to get
I want to remove the bars

geoshow(lat(:), lon(:), long(:),'DisplayType','ImageMap');

Your longitude data "wraps" at 360 degrees.
I speculate that the array starts at about 45 or 50 degrees, increases to 360 degrees, and wraps back to 0 degrees and continues upwards.
If geoshow() does not work for you, then you will need to circshift() your arrays to align them so that the longitude does not wrap back. Or else you need to add 360 to all longitude values after the wrap to get it to display properly.
