For contouring around missing data, a border around the area of missing data that is one grid box wide will also not be drawn (because contouring routines need to know the gradient across a grid box). A better solution is to use 'set gxout grfill' so you can see clearly which grid boxes are defined and which are not. Many users often do a grfill plot, then overlay a shaded contour plot on top of that so you get the smoothness of the contours and the grfill underneath shows through only at the true edges of the valid data. <div>--Jennifer<br><div><br><div><div>On Feb 22, 2013, at 3:02 AM, wendi harjupa wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite">Dear Sir/Madam<div><br></div><div>I want to ask about grads plotting.</div><div><br></div><div>I want to plot hourly data as a contour plot.</div><div>But, the data is not full.
