Irregular data... IDLgrContour vs. contour [message #43100]

Hi all,

I'm a little stuck using IDLgrContour with irregular data. In direct
graphics I would simply type:

contour, zdata, xdata, ydata, /irregular, yrange=[0,60], nlevels=8

where:

XDATA FLOAT = Array[113]
YDATA DOUBLE = Array[113]
ZDATA DOUBLE = Array[113]

Of course, IDLgrContour doesn't accept the /irregular keyword... must I
grid the data myself? If so, can anyone point me to a good gridding
routine? I notice that icontour brings up a 'gridding wizzard'...

Thanks,
Jamie
