QtiPlot

Science by vasilief 347 comments

Hi,

Thanks for your opinions and suggestions!
I'll think about the command line editor, attached to a worksheet, that you suggested! I think that's a good idea, and I'll try to implement this in the future releases of QtiPlot (hoping that I'll have the time, the motivations and the possibilities to continue the developping of this software).

Best regards,

Hi,

Well, first of all take a look at the "worksheet.cpp" file in the archive, and verify that line nr. 1044 looks like this:

parser.AddVar(variables[i].ascii(), &vars[i]);

If it doesn't it's not the right file!
If it does, try modifiing it to:

parser.AddVar((const std::string)variables[i].ascii(), &vars[i]);

and recompile QtiPlot!

Please, tell me that it works!

Hi,

I think that now I have achieved full recognition of pi constant in QtiPlot.
Please try the last update and tell me if I'm wrong!

Hi,

Well, I see what you mean!
The changes I've made only allow to recognize pi in all the user defined functions and not when you define the x plotting interval or the scale limits!

I'll see what I can do for this!

Hi,

Please verify that line 37 in graph3D.cpp file looks like this:

parser.SetFormula((const std::string)formula.ascii());

If not, you're not using the right file!
If it does, I really don't know where's the problem, cause on my Debian Linux machine, it compiled fine with gcc-3.3.4 (now I'm using gcc-3.3.5, and it works too)!

Hi,

Apparently you don't make the connection with the lqwtplot3d libraries, so the most simple way to do it is to log in as root and to copy all the files from the "where qwt plot 3d is"/lib/ directory to the /usr/lib folder.

By the way, this is also explained in the "instal.html" file from QtiPlot the archive.

Hi,

Please verify if the last updated version works for you (normally it should, cause I've used the same compiler and the same Qt version as you and it compiles on my Linux box) and let me know if it does.

And please make sure you're using the files from this last update when you're compiling QtiPlot.

Best regards,

Hi,

I'm using gcc version 3.3.4 (Debian 1:3.3.4-6sarge1) and except from some warnings, the code compiles fine on my machine!
Anyway, I've modified the code and I hope that this time it will compile!
Please retry and inform me if it works for you!

Hi,

I wasn't doing the updates in order to place my application at the top of the list! I only wanted that people using it benefit of the new features or of more stable versions of this application, as I'm constantly working on it!

Sorry, if it bothers you, but I had no intention to cheat ...

I think that from now on I won't announce the updates anymore!

Hi,

Could you send me your code, please? I'll try to use it for implementing .OPJ import in QtiPlot.

Thanks in advance,

Hi,

Thanks a lot for your appreciation and suggestions!

Importing .OPJ files whould be nice, I agree, but I fear it needs a lot of work to understand this file format. Maybe with some help from other developpers interested in this project...

I'll see for the plot layers, but it also seems pretty difficult to implement.

Hi,

I've changed the installation instructions, so please download the qtiplot-0.3.4.zip archive from the following link:

"http://soft.proindependent.com/download.html"

Please keep me informed if it works!

And yes, it's a little bit strange for the RPM packacke, but I can't test it, cause I only have a debian Linux distribution!

Hello,

You should copy the include files of the qwt library to the "$QTDIR/include/qwt" folder, which you must create of course and then try again!

Hello,

Please verify if you find the new scaling feature satisfying, I've tried to improve it!

Concerning the scale ticks, the qwt library only allows to set a maximum number of major or minor ticks, as the scaling depens on the start and end values of the axes. So I think I cann't fix this bug!

For the top and right scales, from now on you can change the number of ticks by changing the configuration of the bottom and left axes respectively (use the axes dialog, the 'Scale' tab).

As they are a sort of secondary axes, their tick numbers will be fixed by the principal scales setup. - Aug 06 2004

Sorry, but I really don't understand where is the problem!

Anyway the style feature is not so important! I wonder if it's necessary at all!

Hello Vasilis,

Thanks for your very useful remarks!

First of all, about qwt, the last stable version is 4.2.0, so you might consider using this one!

About the data plot wizard, it will be soon available! You're right it's a useful feature!

I also hope to implement as soon as possible EPS format export (very useful indeed for latex editing).

3D plots using qwtplot3d library are also on the 'wish to' list!

Concerning the bugs, I think that I've fixed the auto scaling bug in the last update.
The copy-paste of data really needs to be improved, but the highlighting of several columns using the 'ctrl' button was intended to be like this, in order to imitate Origin features (QtiPlot is intended to be a clone of Origin).

For more details on QtiPlot, please take a look at "http://soft.proindependent.com/qtiplot.html"

Ion Vasilief

Hello,

Thanks for your remarks! Maybe you could send me your suggestions concerning the features you'd like to be improved!

The error in the graph.cpp might be due to
an old version of the qwt library. You could probably do a CVS update! - Aug 01 2004

Hello,

I've added an 'install.htm' file to the archive, which explains how to build the application.

In the future I'll put all the files into one folder, you're right!
