Hi,

The issue is solved in the last release of QtiPlot, 0.9.8.3.

Please try it, the conversion should work now.

I hope this helps and best regards,

Hello,

As indicated on the downloads web page of QtiPlot it was required to install Python 2.5.4 separately.

Now I've just added python25.dll to the Windows installers, so just redownloading and reinstalling QtiPlot should fix the issue.

I hope this helps and best regards,
Ion Vasilief

You can download the compiled binaries for Linux for free, you don't need a .deb to use QtiPlot. If you want the .deb package that I maintain, you need to subscript for a maintenance contract. - Apr 11 2008
There's something completely wrong on your system! - Apr 11 2008
What do you mean by corrupted?

I can build QtiPlot 0.9.5 without problems using the source archives. - Apr 10 2008
Hello,

And thanks for the nice words about QtiPlot. Concerning the 'BUT' part:

1) You must use the last Qwt 5.0.2 version as indicated on the QtiPlot webpage. With this version I can't reproduce the bug!

2) Open the export dialog, click the "Advanced" button and check the option:
"Keep aspect ratio"

Concerning your suggestion: this could be helpful indeed. Please add a feature request on the berliOS tracker at:

https://developer.berlios.de/feature/?group_id=6626

so that I don't forget about it!

There's no official description of the .qti file format. Just look at the sources! Anyways the file format will probably changed to a full XML format in the future...

Exporting your data as columns of ASCII, separated by commas, tab or whatever, would be OK!

Hope this helps and best regards,
Ion - Nov 12 2007
Hello,

Thanks for your nice words! Yes, it's true, in order to release the 0.9 version, I had to work very hard, during many hours!
Regarding the import of Origin projects, it's essentially Alex Kargovsky's work! I only helped a little bit on this...

Best regards,
Ion - Sep 21 2007
Hi,

Sorry for not answering sooner and thanks for the bug reports and feature requests.

The thing is that I only rarely watch this page, so you should rather post all your messages to the QtiPlot website on berliOS. There you have a bug tracker and a feature request tool and this way you can be sure that I won't miss any message and that the problems you report will be fixed in the next QtiPlot release.

The link is:
https://developer.berlios.de/bugs/?group_id=6626

Could you please repost all your messages there as bug reports or as feature requests?

I didn't have the time to analyze your messages yet, I will do so as soon as I get a free moment!

Best regards,
Ion Vasilief - Feb 07 2007
Hi,

Again, nothing like this happens with the executable I've compiled, under Linux or Windows.

Check if you link against the last release of Qwt 5.0.0. If you link against an older version, this might be a problem. You'd better download and reinstall Qwt 5.0.0, released on the 18th of January this year.

Hope this helps,
Ion - Feb 01 2007
Hi,

"Segmentation fault" is not meaningfull at all from a programmer's point of view! It just says "Hey, the application crashed", nothing else! If you want to be usefull and get help you should post the stack from a debugger like gdb.

In my opinion your problem could be due to the QtiPlot user settings. You could try to remove them from the /home/your_login/.qt folder and try again!

Here from you,
Ion - Feb 01 2007
Dear Sir,

You must modify the paths in the /qtiplot/qtiplot.pro file in the archive to point to the location of the 3rd party libraries used by QtiPlot on your computer.

Those libraries you don't find with the .a extention are static libraries. Try to find out weather you have the dynamic libraries installed on your system (extention .so). Otherwise you must download and compile those missing libraries.

Also I suggest that you read the qmake documentation from Trolltech and that you Google a little bit to see what static or dynamic libraries are. That's the least amount of knowledge I expect from a Linux user and it could help you understand how to compile QtiPlot and other software.

Hope this helps,
Ion Vasilief - Feb 01 2007
Well,

You're doing something wrong that's for sure!

You could try to compile QtiPlot in debug mode, run it in a debugger like gdb and send me the stack from the debugger!

Otherwise I'm afraid I can't help you!

Ion - Jan 31 2007
Hi,

If you don't want Python scripting support, just uncomment the Python option from the "/qtiplot/qtiplot.pro" file in the source archive.

Hope this helps,
Ion - Jan 31 2007
And what version of Qwt? Are the 3rd party libraries and QtiPlot compiled in the same mode (release or debug)? - Jan 31 2007
Hello,

When I compile it from sources everything works!

Anyway your bug report is useless, since it doesn't specify at least your operating system and your compiler and its version.

regards,
Ion Vasilief - Jan 31 2007
Hello,

Please read and try to understand the install notes provided in the source archive or on the QtiPlot official website: http://soft.proindependent.com/install.html
before posting a compile error message.

Regards,
Ion Vasilief - Jan 30 2007
Hello,

For the moment it's not possible to pipe data into QtiPlot and I don't know how to implement this yet. If you are able to do this, it would be also useful if you sent me the code, so that I can add this feature to QtiPlot.

You can build the documentation for the QtiPlot API using doxygen and the corresponding config file "Doxyfile" in the archive. Unfortunatelly the API is not very well documented yet.

Hope this helps,
Ion - Jan 25 2007
Hi,

Look at the first error line, it tells you everything:

src/graph3D.h:6:31: error: qwt3d_surfaceplot.h: No such file or directory

It's not linked to QtiPlot but to the 3rd party libraries not being found on your computer.

Regards,
Ion - Jan 25 2007
Hello,

The error message tells you that the linker can not find the GSL library. You must edit the qtiplot.pro file in order to specify the correct location of libgsl on your computer.

Hope theis helps,
Ion - Jan 22 2007
Hi,

I don't have a win2K system installed, I use Windows XP and on this I couldn't reproduce the bug you described.

It seems to be a Qt related problem, so I'm afraid I can't do much about it...

Regards,
Ion - Oct 13 2006
Hi,

Thanks for your kind words!
I will try to fix the behaviour of the axes in version 0.8.9.

Best regards,
Ion Vasilief - Oct 13 2006
Hello,

I don't have a PC with Windows 98 available, but well, you can't request too much from such an operating system... In my opinion you should simply stop using it.

Regards,
Ion - Oct 13 2006
Hello,

The .rpm package I provide is built on a 32bits system, so you need to link against a 32bits version of GSL.

Regards,
Ion - Oct 11 2006
Also, you should upgrade to QtiPlot 0.8.8, which solves a lot of the bugs in version 0.8.5.

Regards,
Ion - Oct 05 2006
Could you please send the project file that causes the crash at the following e-mail address:

ion_vasilief@yahoo.fr

I will see what's wrong...

Regards,
Ion Vasilief - Oct 05 2006
Hello,

This problem, due to a reorganization of the code in the Qwt5 library is already fixed. You cand check-out the sources from the SVN repository at berlOS.de: https://developer.berlios.de/projects/qtiplot/

You must check-out the branch called "scripting" at revision 201.

Hi,

Thanks for the bug report, I've fixed it and I will make a bug fixing release soon.

You should check where is your SIP 4.4.5 executable installed. This should be in the first path of the command line, before the -I. What answer do you get when typing sip -V?

Also you should try to make a clean build using:

make clean
qmake
make

HTH,
Ion - Sep 12 2006
Hi,

As you have verified it yourself it isn't yet. The port to Qt4 will be ready in 1 or 2 months.

regards,
Ion Vasilief - Sep 11 2006
I quote from the INSTALL notes on QtiPlot website (same in README.HTML file in the source archive):

"If you want Python scripting support, you will also need to download and install Python 2.4, SIP 4.4.5 and PyQt 3.16. All three of them are included in many Linux distributions. Other versions as those indicated above may or may not work. Specifically, there are known issues with a number of SIP versions and a given version of PyQt will only work with a limited range of SIP versions.

Warning: You might need to edit the "qtiplot-x.x.x/qtiplot/qtiplot.pro" file in the archive and set the path to the SIP executable to point to the correct location of SIP 4.4.5 on your computer, by changing the following line:

unix:system(sip -I /usr/share/sip -t Qt_3_3_0 -t WS_X11 -c $${MOC_DIR} src/qti.sip)"

I don't think that one can be more specific than that!

Hope this helps,
Ion Vasilief - Sep 11 2006
Hello,

You are right, those files are generated by SIP, so you must modify the "qtiplot-0.8.7-2/qtiplot/qtiplot.pro" file in the archive and set the SIP path to point to the correct location of SIP 4.4.5 on your computer. You must do it in the following line:

unix:system(sip -I /usr/share/sip -t Qt_3_3_0 -t WS_X11 -c $${MOC_DIR} src/qti.sip)

Hope this helps,
Ion - Sep 08 2006
Yes, please try PyQt 3.16!
Regards,
Ion Vasilief - Sep 05 2006
Hi,

If you want Python support for scripts, you need Python 2.4, SIP 4.4.5 and PyQt 3.16 installed on your system. From the error message it looks like you don't have SIP installed.

If you don't want to use scripting, just comment out the following line in the qtiplot.pro file:

unix:SCRIPTING_LANGS += Python

to

#unix:SCRIPTING_LANGS += Python

Also reading the README.html file in the source archive might help from time to time...

Ion - Sep 05 2006
Hi,

Sorry for not answering sooner, but I was kind of busy.

Concerning the symbols you want, the best would be to send a patch for the Qwt library itself to Uwe Rathman, its developer.

Regarding the binary packages, it would be great if you could send them to me at the following e-mail adress:

ion_vasilief@yahoo.fr

Best regards,
Ion - Aug 01 2006
Hi,

You could try to build qt-free-win from sources on your win98 system. It will certainly take some time but it should work.

Otherwise you could try the snapshot of the QtiPlot port to Qt4. It's located in the trunk of the SVN repository at the following link:

https://developer.berlios.de/projects/qtiplot/

The port to Qt4 is not ready yet, the 2D plotting is broken and the it's not stable at all. It's planned to be ready for the 0.9 release of QtiPlot, so in about 2 months.

If you need binary packages for Windows I can provide you a working binary in exchange for a 10 euros donation.

With best regards,
Ion - Jun 25 2006
Hello,

Sorry for this mistake! I updated the archives and everything should be Ok now!

Best regards,
Ion - May 17 2006
Hi,

The reason is most probably the fact that QwtPlot3D is not shipped with the QtiPlot archive anymore. You have to install it before you try to compile QtiPlot. The procedure is explained in the INSTALL notes on QtiPlot homepage.

Ion - May 09 2006
Hi,

You can allready achieve this by using the HTML font tags in any of the text dialogs.

Hello,

Thanks for your comments and suggestions! I will see what I can do for the first point.

Regarding the second one, I don't use Grace, and I don't plan to use it, so please could you be more explicit about it? Like sending me a screenshot describing the feature? I don't understand what "allowing multiple fonts to be invoked into single entry" means!

My e-mail address:
ion_vasilief@yahoo.fr

Ion Vasilief - Apr 16 2006
Hi,
Mathematically speeking you are wrong: -1^2 = -1; (-1)^2=1.
From the programmer's point of view the result depends on the precedence of the power operator.

Regards,
Ion - Mar 23 2006
Hi again,

Thanks for your message. You can send me your code contributions or you can report bugs using the following e-mail address:

ion_vasilief@yahoo.fr

Any help is most welcome!

Regards,
Ion Vasilief - Mar 15 2006
Hi,
Just follow the instructions provided in the INSTALL notes for Linux at the following address:

http://soft.proindependent.com/install.html

Running "make install" as root should overwrite your pre-existant Qwt instalation!

Regrads,
Ion Vasilief - Mar 15 2006
Hello,

Nothing is hardcoded into the .pro file, since you can easily modify it using any text editor you like and you can set all the paths to any value you want!

The .pro file provided with the QtiPlot archive is just an example and it reflects the file system configuration on my machine! You should definitely modify it!

Regards,
Ion Vasilief - Mar 15 2006
Hi again,

The reason is that for QtiPlot you need a slightly modified version of Qwt 4.2.0 and because sometimes Ingo Berg the developper of muParser sends me versions of muParser which are not officially released yet, and I include them in QtiPlot.

In the future, when I will port to Qwt5, I will surely follow your suggestion.

Regards,
Ion - Mar 07 2006
Hi,

Thanks for the error message. Just delete those extras words (eg: QwtPieCurve::, etc...) from the specified lines and it will compile. I will make a new release correcting these problems tomorrow.

Ion - Mar 07 2006
