<br> Hi,<br> I have three files like these....<br>199701_01-09_2D.ctl <br>199701_10-19_2D.ctl <br>199701_20-31_2D.ctl <br><br>I wrote a control file like this...<br>dset ^199701_%d2-%d2_2D.dat<br>options template
<br>................................................<br><br>I can open the control file, but while plotting it says<br>Cannot contour grid - all undefined values <br><br>But I can plot from individual files. Where am I doing wrong?
