Re: [Question] limit of Plot buffer size

["Jerry Davison" <davison@xxxxxxxxxxxxxxxxxxxx>]

Aiko,

You may work around the buffer size limitation by first making a contour of a
region with size is less than the limit.  Use the xlimit and ylimit arguments
to specify that the plot axis limits include the entire region of interest.

The smaller data region will be contoured within the larger domain.  Then make
an overlay contour specifying the remainder of the region.  If necessary this
maneuver can be used to divide the contour task into more parts.

This example illustrates the idea:

set data etopo60
contour/xlim=0:360/ylim=-90:90/x=0:180/y=-90:90 rose
contour/xlim=0:360/ylim=-90:90/x=180:360/y=-90:90/over/lev/nolab/pen=1 rose


	Regards,

	Jerry Davison
