[Gnuplot-info] Trouble with Autoscale

[Eric S. <eri...@co...>]

Hi,

 

I have been working with GNU plot and the autoscale function and have been
having some trouble. Using "set autoscale ymax" does not seem to yield the
result that I thought it would. Hopefully someone can shed some light on
this for me. 

Here is an output of my plot directives:

 

 

set data style lines

set grid

set term pbm color

set autoscale ymax

set xrange [0:7]

set tics in

set format x ''

set title "01/04/06 through 01/11/06"

set ylabel "Load Average"

set label 1 "Wednesday 04" at 0.5,-.08 center

set label 2 "Thursday 05" at 1.5,-.08 center

set label 3 "Friday 06" at 2.5,-.08 center

set label 4 "Saturday 07" at 3.5,-.08 center

set label 5 "Sunday 08" at 4.5,-.08 center

set label 6 "Monday 09" at 5.5,-.08 center

set label 7 "Tuesday 10" at 6.5,-.08 center

set xtics ("" 1, "" 2, "" 3, "" 4, "" 5, "" 6, "" 7, "" 8, "" 9, "" 10, ""
11, "" 12, "" 13, "" 14, "" 15, "" 16, "" 17, "" 18, "" 19, "" 20, "" 21, ""
22, "" 23, "" 24, "" 25, "" 26, "" 27, "" 28, "" 29, "" 30, "" 31, "" 32, ""
33, "" 34, "" 35, "" 36, "" 37, "" 38, "" 39, "" 40, "" 41, "" 42, "" 43, ""
44, "" 45, "" 46, "" 47, "" 48, "" 49, "" 50, "" 51, "" 52, "" 53, "" 54, ""
55, "" 56, "" 57, "" 58, "" 59, "" 60)

plot '< cat /data | awk "{ if (\$2 > 004) print \$2 - 004, \$6 }"' title
"host"

 

The labels for the x axis (1-7) do not show up, because the resulting graph
(see http://spot.colorado.edu/~schoelle/untitled.bmp) has it's y values
starting at 2 instead of 0.

I figured with "set autoscale ymax" GNUplot would only adjust the maximum
value on the y axis and leave the minimum values starting at 0. 

I thought maybe I was thinking of this backwards and tried "set autoscale
ymin" - but no change resulted in the graph.

 

What the heck am I doing wrong???

 

Thanks.
