Plot buffer size

[Wendy Wang <wwang@xxxxxxxxxxxxx>]

Hi Ferret_users,

I try to make a contour:

yes? set memory/size=99
yes?  fill u[l=@sbx:5,k=2]

the data set has the following:

 name     title                             I         J         K         L
 U        Zonal Velocity         1:209     1:31      1:15      1:360

But I got

**ERROR: a program limit has been reached: 2332440 points to plot
          Plot buffer size is: 495000

Could any body help? thanks in advance.
