superscript on axis

abdullala — Fri, 05 Feb 2010 16:55:52 GMT

Using ods rtf as output, how to apply superscript to the axis name? I tried {\super } and seems that axis doesnt recognize it. I am using proc boxplot and proc gplot.

If it's a simple 1-character superscript that happens to have a character in the font you're using, you can specify the hex-code for that character, like this:

axis1 label=(font="arial" "Squared" 'b2'x);

proc gplot data=sashelp.class;
plot height*weight / vaxis=axis1;
run;

This tip from Robert also works for the SG procedures:

proc sgplot data=sashelp.class;
yaxis label="X(*ESC*){unicode '00b2'x}";
vbar age;
run;

thank you all very much. too bad the font I am using doesnt support it. I wanted a 'square' sign, cm^2.

That's a good tip, thanks. To get it to work properly with a=90 angled axis you need to include 'b2'x in the string with "Squared". The byte function is handy for that.

[pre]
axis1 label=(a=90 h=14pt font="arial" "Squared%sysfunc(byte(178),$1.)");

proc gplot data=sashelp.class;
plot height*weight / vaxis=axis1;
run;
quit;
[/pre]

@data_null_;

It works great for me. It fixed the problem happens when a=90. Thanks!!
but could you tell me what do 178 $1. mean?

Please, can you advise on this two challenges I am experiencing?

1. How do I write the superscript for -2 or -3 (i.e. X^-3).

2. Please, what is the code for subscripts?

I will appreciate any help.

For axis labels, you will need to use a combination of Unicode characters. Here is a simple example to create X^-4:

ods escapechar '~';
proc sgplot data=sashelp.class;
xaxis label="X~{unicode '207b'x}~{unicode '2074'x}"
      labelattrs=GraphUnicodeText;
scatter x=weight y=height;
run;

You must also use a full-featured Unicode font to get many of the super/subscripts in your text. Referencing the GraphUnicodeText style element will give you one of those fonts that is also appropriate for your style.

Hope this helps!

Dan
