Hallo Stephan,
I'm a bit late, but: thanks! It works! At least with counts up to 9 :-)
The missing parts for a real tag cloud implementation are AFAICS:
1) get min and max count over all tags (minCnt, maxCnt)
2) fit each count (cnt) into a corresponding font size range (minFontsize,
maxFontsize):
fontSize = minFontsize + (cnt – minCount) * (maxFontsize – minFontsize) /
(maxCount - minCount)
So much for the theory. Implementation is left as an exercise for the
reader :-)
