Re: [Gnuplot-info] White point with errorbars in gnuplot 6.0.1

[Yury <yur...@gm...>]

I'm unsure about `pt -1`. Why not use `pt 0`?
The following
```
"battery.dat" t "Power" with xyerrorbars pt 0 lc 
"red"
```
seems to do what you want/expect.

New feature.
Plot styles with errorbars avoid obscuring the central point by placing
a white circle behind it.  You can turn this off by saying "unset pointintervalbox"


gnuplot> help with xyerrorbars    
The `xyerrorbars` style is only relevant to 2D data plots.  `xyerrorbars` is
like `points`, except that horizontal and vertical error bars are also drawn.
At each point (x,y), lines are drawn from (x,y-ydelta) to (x,y+ydelta) and
from (x-xdelta,y) to (x+xdelta,y) or from (x,ylow) to (x,yhigh) and from
(xlow,y) to (xhigh,y), depending upon the number of data columns provided.
The appearance of the tic mark at the ends of the bar is controlled by
`set errorbars`.  The clearance between the point and the error bars is
controlled by `set pointintervalbox`. To have the error bars pass directly
through the point with no interruption, use `unset pointintervalbox`.
Either 4 or 6 input columns are required.

     4 columns:  x  y  xdelta  ydelta
     6 columns:  x  y  xlow  xhigh  ylow  yhigh

[Gnuplot-info] White point with errorbars in gnuplot 6.0.1

[Dmitry <unk...@gm...>]

Hi, this particular version of gnuplot plots white errorbar points with 
the official demo script.

Event If I set "pointtype -1", I still get the same white points, please 
see the attached demo script.

The previous version of gnuplot worked as expected, no white points.

I'm using gentoo.

Is this new feature or some kind of bug?

Thanks!

No attachment made it through list mailing list processor.

You're probably better filing a support request or bug report at our 
SourceForge site.

[Gnuplot-info] Accuracy of the calculation

[Patrick D. <pd...@gm...>]

Hello,

On the attached figure, there is one point off (the lowest one).
I can only explained this by a wrong calculation.
~10% of my samples show such a behavior (see the other plot).
Some ideas?

Thanks

Hello,

This is probably not what you are looking for, but in any case, using 
Maxima (maxima.sourceforge.net) I can generate a gnuplot input file with 
something similar to what you want, with the following commands:

d:%pi/10$
f:makelist([5,[th,5*d,6*d],[ph,i*d,i*d+d]],i,0,20)$
f:append(f,makelist([5,[th,4*d,5*d],[ph,i*d,i*d+d]],i,0,20))$
f:append(f,makelist([5,[th,3*d,4*d],[ph,i*d,i*d+d]],i,0,20))$
f:append(f,makelist([5,[th,2*d,3*d],[ph,i*d,i*d+d]],i,0,20))$
plot3d(f,[transform_xy, spherical_to_xyz],[grid,1,1],[z,-5,5],[gnuplot_script_file,"spherical_rectangles.gpt"],nolegend);

The last command will show you the location where the 
"spherical_rectangles.gpt" file was saved.

[Gnuplot-info] Plotting rectangles in spherical coordinates

Re: [Gnuplot-info] Website not available at gnuplot.info

[Tait <gnu...@t4...>]

As a workaround, you might use https://gnuplot.sourceforge.net/ instead (and https://gnuplot.sourceforge.net/docs_6.0/gnuplot6.html for documentation).

Gnuplot uses SourceForge. If you try
  gnuplot.sourceforge.net is an alias for projects.sourceforge.net.cdn.cloudflare.net.
  projects.sourceforge.net.cdn.cloudflare.net has address 104.18.37.111
  projects.sourceforge.net.cdn.cloudflare.net has address 172.64.150.145
  projects.sourceforge.net.cdn.cloudflare.net has IPv6 address 2606:4700:4400::6812:256f
  projects.sourceforge.net.cdn.cloudflare.net has IPv6 address 2606:4700:4400::ac40:9691
... those IPv6 addresses might look familiar.

What CloudFlare describes from your link:
> A non-Cloudflare domain cannot CNAME to a Cloudflare domain unless the non-Cloudflare domain is added to a Cloudflare account.
... is (approximately) what's happening, although without exactly using a CNAME. It was working at some point, so I guess CF has now changed it so it no longer does. We don't have the ability to add gnuplot.info to SourceForge's CF account, so we may need to get a hold of Clark again.

People (including me) using IPv4 instead of IPv6 probably won't see this error, because gnuplot.info's IPv4 address points to SourceForge directly (204.68.111.101), not Cloudflare. But if -- hypothetically -- gnuplot.info did point to the projects.sourceforge.net.cdn.cloudflare.net v4 address, it would also generate the 1001 error.

And I get the same 1001 error over IPv6 that Aleksandr sees.

[Gnuplot-info] Fit table agaisnt table

[Patrick D. <pd...@gm...>]

Hello,

I am reformulating a previous question.
I have 2 sets of data that I read as tables.
I would like to fit a set of data against the other set of data by
adjusting parameters, like a coefficient amplitude.
However, I do not know how to do it.

Thank for your help.

[Gnuplot-info] Website not available at gnuplot.info

[Aleksandr D. <ale...@pr...>]

Hello gnuplot community,

There's indeed a problem with website availability at gnuplot.info, however it might not be strictly DNS problem, but rather some Cloudflare misconfiguration.

The domain name resolves normally and points to some IP:

> dig +short gnuplot.info.
204.68.111.101

and in case of IPv6 specific AAAA records lookup:

> dig +short AAAA gnuplot.info.
2606:4700:4400::ac40:96912606:4700:4400::6812:256f

However when I try to reach it via HTTP request I get the following response:

Quick googling brought me to this documentation page with "Resolution" section - https://developers.cloudflare.com/support/troubleshooting/cloudflare-errors/troubleshooting-cloudflare-1xxx-errors/#error-1001-dns-resolution-error.

I suspect there's some misconfiguration in case you use Cloudflare as your load balancer/DNS zone hosting. There's indeed a workaround - you can access the same gnuplot website by just accessing the site by www.gnuplot.info domain (which, by the way, doesn't have any AAAA records).

I see from the mailing list archives that I'm not the only person facing, so I'd like to ask people who support the website to take a closer look at this issue.

I think it's an important issue, because one of the links that points to the domain with 'www.' part is the one that is on the documentation page (http://www.gnuplot.info/documentation.html) and it leads to the gnuplot online documentation (http://gnuplot.info/docs_5.5/gnuplot5.html). It means that newcomers (like myself) won't be able to access the documentation and consequently would not enjoy gnuplot's features.

You could potentially fix the issue by altering DNS zone file to not include AAAA records or to put there actual IPv6 address of the server that serves the site.

Dear gnuplot community,

I have noticed, that the project website is only available
at www.gnuplot.info and not at gnuplot.info. The latter,
in fact, gives a cloudflare DNS Resoultion Error. I
think it would make sense to redirect gnuplot.info to
www.gnuplot.info as it would make it simpler for users to find
the webpage. (The 1st search result on Duckduckgo for
"gnuplot" is for example gnuplot.info.)

Kind regards,

Peter,

Your procedure worked fine, many thanks:

and whereis Qt6Core.pc returns no result.

Re: [Gnuplot-info] Install error 6.0.1 on NUC 5 Raspian Desktop Bullseye

[Peter R. <p.r...@sh...>]

Assuming you have the QtCore file installed, do you also have the 
pkgconfig file called Qt6Core.pc? This, AFAIU, provides the include path 
to the compiler without which you will get an "I can't find QtCore" error.

If it's missing for you then this is interesting because I encountered a 
similar problem on Mint (which uses the Ubuntu build of qt6core-dev, 
which, for some reason, is missing the .pc files). I thought the Debian 
version had the .pc files, but...

Re: [Gnuplot-info] Building gnuplot 6.0.0 on Linux Mint

[Peter R. <p.r...@sh...>]

Just an update: It turns out the absence of the .pc files was flagged 
with the Ubuntu maintainers on 2022 in connection with libcamera! They 
have now accepted there is a problem although no timescale for a fix.

[Gnuplot-info] Install error 6.0.1 on NUC 5 Raspian Desktop Bullseye

[Dan H. <db...@su...>]

Trying to install gnuplot 6.0.1 on an NUC 5 running Raspian Desktop Bullseye and it throws this error:

qtterminal/qt_term.cpp:51:10: fatal error: QtCore: No such file or directory
   51 | #include <QtCore>
      |          ^~~~~~~~
compilation terminated.
make[3]: *** [Makefile:1044: qtterminal/qt_term.o] Error 1

Any pointers appreciated.
