<div>I have a program that pulls temperatures out of a netCDF file, puts them into a binary file, and plots them in grads. I also contour and shade the map using oacres. It actually produces quite a nice image, smooths out all the bad obs, but I was wondering, is there any way I can use oacres to contour every value on my map? I'd like to take this image, and use it as a quality control product where bad obs stick out, thus making it a little easier to identify where the problem sites are. This would essentially produce bulls-eyes where bad data points exist, and this is exactly what I'm looking for.

<div>As an example, I made a plot of temperatures this morning, generally in the upper 60s to lower 70s. However, there are 2 points that stick out with values of 32. I messed around with the oacres radii, taking it all the way down to
0.1, and while I start to get a bulls-eye, it's in the wrong area, and doesn't contour all the way down to 32. When I go to make my contour, GrADS spits out "Contouring 65 to 75 interval 1".</div>
<div> </div>
<div>So I tried to set clevs 28 30 32...etc....74 76 78 80, then d oacres(dummy.2(t=1), ts,0.5), and while it spits out "contouring at clevs 28 30 32...etc...", the lowest contour I see on my map is 64. </div>

<div>Does anyone have any idea how to make grads contour bad data to make it stick out? It seems oacres is trying to smooth it out too much.</div>
