Hi Ahmed,
That looks to me that at the bottom of your plot that your data field
quickly drops from > .9 to > .1.. Thus, I think there are 9 contour
lines immediately next to one another, and thus the labels all look like
they are on line. (Notice the 0 "line" appears thicker than the others.)
You can check this by setting trYMaxF = 3.0 and trXMaxF = 3.0 to zoom in
on your plot.
Looking at your script I see you are reading in an ascii file and are
not setting the _FillValue attribute. Does your data have any missing
data? Regardless, you should set the @_FillValue appropriately.
You might want to use the printMinMax procedure to look at the minimum
and maximum values of your array as well:

Finally, if those values near the bottom of your script are indeed 0 or
some other small value you can use the where function to set those areas
= @_FillValue if you would like:

Hope that helps!
