<div>I have it in my script, so it can't be the problem. When I run the script without the negative signs, no problem. But not with them...</div>

'define dy = 're'*cdiff((lat*(3.14159/180)),y)'<br>

'set ccolor 4'<br>
'd (dzx/(-1*dx));(dzy/(-1*dy))'<br>

will not plot down height gradient vectors. I just get blue circles about every grid point. If I remove the negative signs, I get the traditional gradient vectors, but with them, I get the circles. I have tried putting the negatives in so many different places
and same result.<br>
