I have a data set that I'm trying to interpolate, and in some cases there are large swaths of area that are surrounded by points, but don't contain any points. This produces a graph where these interior regions have values determined by the nearest points.<div>
<br></div><div>Rather than assuming that these points are accurately represented by the surrounding points, I would prefer to not render those grid points, and only show grid boxes which are actually representative of data. Is there a way to do this? I was thinking I could add second field and assign opacity to that, but I can't figure out a way to get the field to be 'true' if there are points enclosed and 'false' otherwise (or to simply count the number of enclosed points.)</div>
<div><br></div><div>Any ideas?</div><div><br></div><div>Thanks for any suggestions!</div>
