Bar Charts

[Eric Altshuler]

Hi Jennifer,

I thought the skip function was only for horizontal dimensions (X,Y). You are suggesting that it also works for T (or even Z)?

Hi,


I solved the 3 hr interval issue below by changing the ctl file to 6hr
steps. The skip() function would have done the trick too:
set t 1 last
set x 1
set y 1
d skip(var,2)






Can anyone help me on the multiple lines for X axis???


Similar to the time step but I want to do my own labelling.
The following may achieve your desired result -- I used 'q gxinfo' to get the x and y limits of the plot, which were

Page Size = 11 by 8.5
X Limits = 2 to 10.5
Y Limits = 0.75 to 7.75


Then I used these commands:Â

'set xlpos -0.4'
'set xlabs k | l | m | n | o '
'set grads off'
'd t'
'set line 0'
'draw recf 1.98 0.27 10.52 Â 0.70'
'set xlpos -0.2'
'set xlabs f | g | h | i | j '
'd t'
'draw recf 1.98 0.47 10.52 Â 0.70'
'set xlpos 0'
'set xlabs a | b | c | d | e '
'set ccolor 1'
'd t'


Where t is a 1-dimensional time series. The labels "a" through "o" can be modified to suit your needs -- they can have more than one character and will be centered on each tic mark. The 'draw recf' commands are to cover up the extra axis line that you don't want to see. Another option is to use 'draw string' for each line of every tic label, but that may be more work than the above.Â

Hi,


I have 2 questions with regards to bar charts.


1. I have grib in 3hr interval time steps. I want show a variable over 6hr
time steps. e.g   t 1, t 3, t 9 etc.. I cannot see any obvious way to do
this
from within a script.


2. How can I print the x axis labels over multiple lines. I notice that by
default when the x axis labels are time steps, it prints the time,month
and
year of 3 lines. How can I embed a line break into the label?


Regards
Steven
