[gradsusr] "Delta" notation

[Huddleston, John]

Thank you Alan and Charles,

Max, the following will draw delta = 1.2 and sigma = 0.8 in greek notation on two different locations on the screen.

draw string  8 1 `3 D `0 = 1.2
draw string  8 2 `3 S `0 = 0.8

Max,

1) Check if you have "font.gs" from http://www.iges.org/grads/gadoc/library

2) start GrADS and run "font.gs" as:
ga-> font 3

and you should see a screen with multiple columns with pairs of 
characters (the second character is the "font 3" character; I think this 
set contains the characters you want)...

3) Prof Alan Robock in his email to the Listserv describes how to use 
these fonts (also see http://grads.iges.org/grads/gadoc/font.html):

Subject: Re: Using fonts

Dear Jose,

To use the different fonts, there are 2 GrADS scripts that can be used
by using the command run,  font.gs and  tfont.gs (see below).

ga-> run tfont.gs

to show examples. Look at the text in tfont.gs to see how it was done.
Use font.gs to display the available fonts, e.g.:

ga-> run font.gs 3

You use it as follows:

run font.gs #

where # = 0 - 5

0 = helvetica
1 = roman
2 = italics roman
3 = symbols
4 = bold helvetica
5 = bold roman

To do sub/sup scripts use the ` [back accent] character:

`b below
`n normal
`a above
`# change the font to 0-5

e.g.,

ga-> set strsiz 0.4
ga-> draw string  1 2 `123.5`3.`0C
ga-> draw string  1 1 S`b0`n = 1368 Wm`a-2`n



tfont.gs:

pt = ' S`b0`n = 1365 Wm`a-2`n  `5CO`b2`n  `2CO`b2`n'
te=' `123`3.`1C'
gr=' `38 9G 7 pmlt > , < * . b'
it=' `2Italics'
bor=' `5Bold Roman'
boh=' `4Bold Helvetica'
he=' `0Helvetica'
'set string 7 bl'
'set strsiz 0.4'
'draw string 1 1'pt
'set string 2'
'draw string 1 2'te
'set string 13'
'draw string 1 3'gr
'set string 9'
'draw string 1 4'it
'set string 8'
'draw string 1 5'bor
'set string 3'
'draw string 1 6'boh
'set string 6'
'draw string 1 7'he

font.gs:

function font(arg)
if (arg='')
  arg = 1
endif

fch = '!"#$%&''()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOP'
fch = fch % 'QRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz{|}~'

'set font 1'
'set strsiz 0.3'
'set string 1 c 3'
'draw string 5.5 8.0 Font Set 'arg
x = 1.0
y = 7.0
i = 1
'set font 0'
'set strsiz 0.2'
'set string 1 c 1'
while (i<95)
  'draw string 'x' 'y' 'substr(fch,i,1)' `'%arg%substr(fch,i,1)
  x = x + 1.5
  if (x>10.5)
    x = 1.0
    y = y - 0.4
  endif
  i = i + 1
endwhile
