best image plotting routine [message #66466]

I often use a simple contour command (with /fill) to plot an image,
however that is not practical for very large images with NANs in it.
One must use /cell, and that takes forever to render, and creates
120mb postscript files.

what is the best routine to use to create this plot of an image?
Note there are 2 requirements.

1) it must accept "all" graphics keywords.
- i use xtickformat to print julian days for instance, ytickv, ytickname,
log axis, etc

2) it must create scalable and small postscript files
- a bitmap into a postscript is not acceptable. the quality
is too low for publication.

I've just spent a while wrestling with this, and because I had
to get it done now, ended up using
> shade_surf, ax=90,az=0, shade=data,ztickname=blank

which is wonderful, and quickly creates a nice small postscript file,
but obviously this is a huge waste (2D -> 3D ->2D).

cheers,
bob
