[gradsusr] vector plotting problem

[Rowell, Mason D.]

Jeff,

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...

All,

For whatever reason,

'define dx = 're'*cos(lat*(3.1419/180))*cdiff((lon*(3.14159/180)),x)'
 'define dy = 're'*cdiff((lat*(3.14159/180)),y)'
 'define dzx = cdiff(HGTprs,x)'
 'define dzy = cdiff(HGTprs,y)'
 'set ccolor 4'
 'd (dzx/(-1*dx));(dzy/(-1*dy))'

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.
