The tag is searched in the surrounding vector graphics and the contents of the <psfrag> is substituted for it:

<psfrag tag="x-axis">x-axis</psfrag>

For this I use of course the fantastic Psfrag package. Is <psfrag> empty, tag is substituted for itself, which means that only font and size is adjusted to the main document:

<psfrag tag="Diagram"/>

If you want to erase something from an image, you have to replace it with white-space:

<psfrag tag="was dull"> </psfrag>

align determines alignment relatively to the replaced tag:

left on the same baseline.
right on the same baseline.
centered on the same baseline.
horizontally and vertically centered.

number is "true" by default, if tag is obviously a number, or if interval is given, else "false".

constrast="boxed" sets the substitution on a white rectangle. constrast="inverse" shows the substitution in white colour. One of both may be necessary for too dark/chaotic backgrounds.

relsize should be clear.

interval consists, if given, of three semicolon separated numbers: start, end and step. Thus interval="0;10;1" yields automatically Psfrag substitutions for all numbers between 0 and 10. This is very convenient for EPS files with a labeled axis. By the way, tag plays in this case the role of a pattern for the numbers in the EPS file. This works somehow accoring to the DecimalFormat routine of Java 1.1, if anybody knows this.

Some examples:

<psfrag tag="#" interval="1;10;2"/>

replaces 1, 3, 5, 7 und 9 by itself (i.e., it changes the font only). Now for something more complicated:

<psfrag tag="#.0" interval="-4.5;-6;-0.5">#,0</psfrag>

replaces -4.5, -5.0, -5.5 and -6.0 by the same numbers, but with a comma instead of a point (for our non-English friends). Additionally,

<psfrag tag="#.0" interval="-4.5;-6;-0.5">#,#</psfrag>

does the same, but in the output post-comma digits (and the comma) are omitted where they are zero anyway. Last example:

<psfrag tag="0.0" interval="-1.5;1;0.5">#,#</psfrag>

does the following substitutions: -1.5 → −1,5, -1.0 → −1, -0.5 → −0,5, 0.0 → 0, 0.5 → 0,5 and 1.0 → 1.

Besides, it doesn't do any harm if you declare too many replacements, so you can use the same <psfrag> for all your diagrams, for example.
