Please take a look at the data from here:

Example Data:
http://www.d-tacq.com/tmp/060x.COOKED.tgz

untar, open DirFile, plot V01 .. V08
The size is 100K (already reduced from 6MB).

Example Output:
http://www.d-tacq.com/tmp/kst1.7-good.pdf :
		shows sine waves scaled +/-6V*
http://www.d-tacq.com/tmp/kst2.0-bad.pdf  :
	same data, shows sign and scaling error.

* is it good? On closer inspection, the vertical steps do not look 
correct. However, that's a separate issue, could be in the data.

ps: OT:
Another change from 1.7 .. 2.0 : selecting multiple fields.
1.7 allows an old-style click, shift-click to select a range.
2.0 doesn't do this, but allows a click and drag, which is cool, but I 
find it harder to use. Could we have both methods please?.
