Re: [Jmol-users] super and subscripts in labels

Oh Bob, you are too fast for me...
That <sup> way sounds easy and good.

OK, now with my trick. I looked up some Unicode characters for the scripted numbers. 
Last time I did this, I was searching for several arrows, some work, some not. But the 
subscripts and superscripts all work OK. Codes are below.

Instead of directly coding the chars (which also works), I engineered a little bit to have 
some reusable solution:

function JmolLabelSuperscript(n)
{	if (n==0 || n>3) { return '\\u207' + n }
	if (n==1) { return '\\u00B9' }
	return '\\u00B' + n 
}
function JmolLabelSubscript(n)
{	return '\\u208' + n 
}

and then:
jmolButton('font label 24 serif; select atomno=3; label "Ca' + JmolLabelSubscript(3) + '(' 
+ JmolLabelSuperscript(3) + JmolLabelSuperscript(3) + 'PO' + JmolLabelSubscript(4) 
+ ')'+ JmolLabelSubscript(2) +'"', 'symbols in label')

Oh, now I see that superscripted 1, 2 and 3 are smaller than the others (they come 
from a separate CharCode table)

/*
	\u2070 = superscript 0
	\u00B9 = superscript 1
	\u00B2 = superscript 2
	\u00B3 = superscript 3
	\u2074 = superscript 4
	\u2075 = superscript 5
up to 
	\u2079 = superscript 9

	\u2080 = subscript 0
up to 
	\u2089 = subscript 9
*/

I will post this in JmolWiki, Recycling Corner, so that all of us can find it in the future.
