spurious errors in ticks

[<pl...@pi...>]

Hi,

I just ran up a very simple plot file for some simple time data.


set xdata time
set timefmt "%d/%m/%y"

datafile='bois.log'
plot datafile using 1:2


when I tried to plot it I got a series of unexpected errors:

gnuplot> load "bois.gnu
          "bois.gnu", line 7: warning: Too many axis ticks requested (>9)
          "bois.gnu", line 7: warning: Too many axis ticks requested (>9)
          "bois.gnu", line 7: warning: Too many axis ticks requested (>7)
          "bois.gnu", line 7: warning: Too many axis ticks requested (>9)
          "bois.gnu", line 7: warning: Too many axis ticks requested (>7)
          "bois.gnu", line 7: warning: Too many axis ticks requested (>9)


After some testing I found that this was caused by calling gnuplot form 
an xterm& when the parent terminal had subsequently been closed.

I am not sure how closing the parent would affect the environment of the 
xterm running gnuplot but clearly it does. What could be changing that 
is causing gnuplot to fail to calculate the ticks?

Is this to be expected ?

TIA,

Peter.
