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,

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

Science by vasilief 347 comments

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,

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!

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,

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,

Science by vasilief 347 comments

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,

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!

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.

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

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,

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)

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...

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.

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.
