Hi SPLUSers,
I recently got a new computer. Everything seems to be working well on
both old and new machines except that on the new machine if I try to
convert an SPLUS graph sheet (specifically a map with overlaid image
plot) to editable graphics, the graph only partially redraws and nothing
is selectable. The odd thing is that if I then export this graph to a
windows metafile, the graph is there in its entirety. If I create the
graphsheet as editable in the first place, the graph only partially
draws. Shrinking or unshrinking windows, or automating the redraw with
code do not help.
We've tried replacing the video card, no change. Tech support has
suggested several things, none of which solved the problem. All other
software is problem-free on the new machine. Has anyone else
experienced a similar problem and if so how was it fixed?
Hardware/software particulars:
SPLUS ver 6.1 (same problem with ver 6.0 upgrade 2)
Windows 2000 Server (was Windows 2000 Pro on old machine)
Intel, 2.2 Ghz, 524 Mb Ram
1st graphics card on new machine: Rage Fury Pro/Xpert 2000 Pro with 32
MB memory.
2nd graphics card on new machine: ASUS V7100Magic v11.01c, max
resolution 1600x1200x75Hz, 32 MB memory
(same problem with both cards)
Old machine's graphics card (works fine): Nvidia Riva 128/128ZX with 8
MB memory.
Here is a function with the problem. The data are fake, but in the same
range as my real data.
function()
{
xlim <- c(-116., -85.)
ylim <- c(25, 60.)
graphsheet(num.image.colors = 7)
#### Data
x <- -143:-68
y <- 17:74
z <- matrix(0, nrow = length(x), ncol = length(y))
z[x > -125 & x < -115, ] <- 1
z[x > -115 & x < -100, ] <- 2
z[x > -100 & x < -90, ] <- 3
z[x > -90 & x < -85, ] <- 4
z[x > -85 & x < -80, ] <- 5
z[x > -80 & x < -70, ] <- 6
#### draw the map
usa(xlim = xlim, ylim = ylim, lwd = 3.)
#### add the image
image(x, y, z, add = T)
#### redraw the map over the top of the image
usa(lwd = 3., add = T)
}
Thanks for any suggestions, KG
