[Gwyddion-users] windows 32 bit graph and download issues

[Andrés Muñiz Piniella]

I am using 2.44 32 bit on windows xp (yes I know it is old).

I noticed that measure distance in graph gives me a value in length but not height.

I was looking to reinstall again but I get sec_error_unknown_issuer
and the address is 139.143.6.160:9091 when following the link from gwiddion.net download page.

So the delta z value is 0? Or do want to extract line profiles? This is
a separate button.

I guess you tried gwyddion.net ;) ->
http://gwyddion.net/download.php#stable-windows ->
http://sourceforge.net/projects/gwyddion/files/gwyddion/2.44/Gwyddion-2.44.win32.exe/download

Maybe there has been some unavailable server in the
SourceForge.net-work, so could simply retry the download.

Best regards,
Robb

That should only happen when you use intersections and move the vertical
line to a region without any data – i.e. nothing to intersect the line
with.

139.143.6.160 is an NPL IP address. So, most likely some network
shenanigans there (man-in-the-middle subversion of certificates by
proxies, etc.)

yep, I expect it with no data, but I am using intersection on an RHK force curve.
the value is empty not zero.

*face palm* thanks, I'll do a whois next time. there probably was a memo I missed, sorry for the noise.

OK, the curve probably goes backwards then (or back and forth and then
to the 4th dimension). A number of functions do not work when graph
curve abscissae are not in ascending order.

I would simply forbid it. Unfortunately, it is too late for this.
Still I prefer fixing things that create non-function-like curves to
making things work with such curves. So please send me the file and I
will correct the naughty module. Approach and retraction should be
hopefully two separate curves so it is just matter of reverting the data
point order in the import module.

Sorry for delay!

forgot to say, there is meta data on the file as well, but I can't get to it unless I captured am Image (these only have spectroscopies).

OK, should be fixed now.
