Hi,

Not sure, but it looks like you're not linking against the modified version of Qwt which comes with the QtiPlot archive (in the "3rdparty/qwt" folder).
If you allready have Qwt installed on your machine you shoud override it with the version provided by QtiPlot.

Hi,

Are you sure you link against the modified version of Qwt? Please try to recompile it and copy the lib to the /usr/lib folder.

I've seen that there's indeed a bug linked to unsychronized ticks for the newly created plots, but this behaviour disapears when you change the scale type for the right/top axes (the scales are resynced then).

Hi and thank you for your bug reports!

It's a bug indeed and it seems to apear only when you don't enable the lables for the scale division.

I'll see if I can fix this for the next release.

Hi,

You're right, the ticks are different and this is a bug, thanks, I'll try to fix it in the next release.

Concerning the axes corners, this is a known problem of Qwt, the only thing that you can do in order to avoid this is to draw the canvas frame also!

Hello,

The problem is that I've done some modifications to the Qwt 4.2.0 library and it's this modified version, which comes with the QtiPlot archive ("3rdparty" folder) that must be used and linked against. This is specified in the INSTALL instructions. The bugs you described do not occur when you compile QtiPlot following these instructions.

Did you compile QtiPlot yourself or you used a package made by someone else?

Hi,

In fact when you export a plot to EPS the file is empty, unless you check the box enabling to open the export options dialog. This is a bug and I will fix it in the next release. Meanwhile you can export your plots to EPS, by checking that option.

Well, knowlegde is still free for everybody: the code sources are available and the install instructions are available. If one can read, one could also compile and istall QtiPlot!

For the rest, I'm just a normal guy, who must pay his bills, so money is important for me. If I was a millionaire, I would give the binaries for free to everybody, since programming is for me a passion.

If you or somebody else are willing to pay me a decent salary just to stay at home and develop QtiPlot, then I agree with you, the binaries should be free. But since nobody does it and donations are not so frequent, I need to get some money out of it. So, I provide SERVICE for the binaries. At a very cheap rate: ten euros is less then a haircut in Germany, or equals two beers in a bar in France. So, please, spare me! OK?

There are allready people doing this! If you do some google search you will see! So no problem for me, do it if you know how to, but I sincerely doubt it! Otherwise you would not be complaining about the binaries!

In my opinion, you're somehow just another Windows user (even if you don't know it), taking free software, in the sense of open source, for "freeware"!

Just because not everything is free in life (QtiPlot is: the sources are free for everybody who knows how to use a compiler) and because work and knowledge must be rewarded!

If you don't know how to compile QtiPlot by yourself, you can still read the install notes and learn how to do it. Or you can pay me the 10 euros I ask for this service!

Hi,

It seems that you don't read my replies to your messages! In a previous reply I have explained that when you import an ASCII file, you might need to specify the column separator in the "Import ASCII | Set import options..." dialog!

It is impossible to detect the column separator and the default is set to be the TAB. If your file has the SPACE character as column separator, you need to select this one. Sorry, but it's like this!

Regarding the "color.h" file it's not needed anymore, but I forgot to update the .pro file. This is allready fixed in the .zip archive, but not in the .tar.bz2 one.

Regards,
Ion Vasilief - Nov 25 2005

QtiPlot

Science by vasilief 347 comments

Hi again,

This happens because the default column separator is now the TAB character. So, before opening the file, you have to edit the import ASCII options (via "File|Import ASCII|Set Import Options...") and to set the separator to SPACE.

I just checked it and your bug doesn't occur. What you describe might happen if the format of the columns you plot is other then Numeric. You can change the data format of a column via the Column properties dialog, accessible by double-clicking on the column header.

I hope this solves your problems.

P.S. You must link QtiPlot 0.6.9 against the modified version of the Qwt library, provided in the 3rdparty folder of the archive.

Hi,

Thank you for your message and for the kind comments. Concerning the html tags, most of them work, but unfortunately the alignement tags don't, because in the code I'm forcing all text to start at the first column. I'll see what I can do for this, but I must tell you that this is not a priority on the "to do" list.

Regarding the documentation, I don't think I'll ever have the time to write it myself as I'm to busy with the code (and I also have to go to work, unfortunately), so any help is most welcome. I started implementing a basic help using html files a long time ago and, as you may have noticed by using the application, there's no progress in this direction.

If you ever plan to write some doc files, they should be in .html format, something like the Qt doc.

Hi,

I'm not sure which is the best way to go. Maybe you should get rid of gcc 4 for the moment. If you keep it I fear that you should also compile the Qt libraries yourself, together with Qwt, QwtPlot3D and GSL.

Please tell me if you succeed in compiling QtiPlot.

You get it right about the styles, but I really don't understand why it doesn't compile. Maybe you should verify if you're using the right "include" folder in your INCLUDE PATH.

Hi,

Normally you should have a "qplatinumstyle.h" file in the include files of your Qt distribution. If you don't, you are not using the right Qt version or there's a problem with your Qt distribution. You need at least Qt 3.2.1 for QtiPlot.

Hi,

Generally, posting two times the same message, doesn't help. More particularly, the only important thing in an error message is the first line containing the word "error"! The rest is almost useless, so please think about that when you post a compiling error message!

Regarding that error, I think that it is solved in 0.5.8 version, available for download on QtiPlot home page. It was due to the fact that I cann't test it on Linux with gcc, as I'm working on the computer of a friend which only has Windows installed.

Exactly! I've never had a personal computer! I started working on QtiPlot last year, when I was working at the university in Lyon, developping the application after work or during week-ends (driving my girlfriend nuts!).

Now, as I'm unemployed, I can't afford to pay an appartement, so I live some time to a friend, some time to another, and I use their computers to read my e-mails. And latelly I was "tolerated" in the lab where I made my Ph.D., as I was working on some papers, so I could do some coding too.

For a decent computer, I think I'll need at least the double of what I've got up to now from donations (about 375 euros). It might take some time, but I'm optimistic!

As I said, people are free to build their own binary QtiPlot packages and to make them available online, and if you do some google search you'll surely find something for different Linux distros, not necessarely .RPMs.

And I don't understand why you find irritating my donations for binaries system: the webhosting is rather expensive
and the bandwidth for QtiPlot homepage is limitated so I cann't afford to have too much traffic. And, by the way, this system could help me to buy a computer and to continue the project... - Feb 28 2005

QtiPlot

Science by vasilief 347 comments

I'd like to remind you that QtiPlot is under GPL licence, so you can freely build the application from sources, you can build your own RPM package, you can even sell it if you want (but in that case you should buy a Qt commercial licence).

So if you don't want to make a donation, you're not obliged, you can still use the application, all you need is to spend some time to read the install instructions (which are very clear) and maybe do some internet searching ...

Concerning the title of your message ("show me the money"), I can tell you that all the money I've got from donations is about 350 euros, so for the moment I cann't even dream about buying a computer (I don't have one, I'm unemplyed and I'm living with a friend who allows me to use his computer when he's not at home). So don't "worry" and don't get "irritated", I don't think I'll ever make a fortune from donations!

And, sincerely, I doubt that you would donate something for QtiPlot, even if you had the binary packages available! - Feb 27 2005

You don't have to install the Fast Mathematicl Parser library, because the sources are included in the QtiPlot archive and the messages you get when you compile QtiPlot are mainly warnings due to the parser library.

I'm not sure where's the problem, cause on my machine (under Unix Debian and under Windows too) it works fine.

Maybe you could try commenting out the lines calling the "makeCurrent()" in the graph3D.cpp source file, from functions:

and void Graph3D::initCoord()
(line 202), like this:
