[Fxplot-users] Building with configure

[Julien de C. <jul...@te...>]

Hi,

I am just starting using FXPlot within my application.It looks ideal for 
what I want to do: 2D plots.

I have a few comments:
* I am not familiar with CMake. I redid the makefile system using 
aclocal, automake (etc...) to get a configure script. Let me know if 
anyone is interested in it.I am using Windows XP - SP2 with MinGW and 
fox-1.6.9.

* In the settings box, I would like to have a "Hide curve" instead of a 
"Remove curve" - to enable the possibility to show it later. What would 
be the best way to change that?

* I haven't got in the details of FXPlot coding yet. Is there an easy 
way to output and read the user specifications (eg position of label, 
color of lines and symbols...) in a registry? I am trying to get the 
look and feel to be resumed between start of the application.

* I am planning to release a new version of my application linked to 
FXPlot. My application is GPL licensed at 
http://sourceforge.net/projects/mywej. Is it ok if I provide FXPlot as a 
.dll for Windows? What "thanks-you" mention would be appropriate (to be 
in documentation, and about box)?
This software includes and uses FXPlot 
(http://sourceforge.net/projects/fxplot)?

Kind regards,
Julien

Re: [Fxplot-users] Problem in axis label

[<jea...@fr...>]

Rafael,
thank for the tip, i'm going to check it.
However, note that the top axis label is not working either, which then s=
hould
not come from vertical drawing fonts.
Anyway, i'll keep you informed on all this.
Cheers

Re: [Fxplot-users] Problem in axis label

[Rafael de P. S. <ra...@rp...>]

Hi Jean-Do,

Yes, there is a problem with left and right axis label. Actually I was 
waiting for vertical drawing fonts to be implemented in FOX, appears 
that version 1.6 has it.
You can try a solution, check the code near to line 209 of file FXAxis.cpp:

    //FIXME : draw vertical text
    else if(flags&FXAxis::Left){
    }
    else if(flags&FXAxis::Right){
    }

Maybe you will need to adapt FXAxis::getDefaultWidth() in order to 
accomodate the additional space for the label.
If you got something working I would be very glad to add it.

Cheers,
Rafael

[Fxplot-users] Problem in axis label

[Jean-Dominique B. <jea...@fr...>]

Rafael,
have you tried to add a lablel to the left axis of the curves.cpp test 
file using the line :
        view->getLeftAxis()->setLabel("Y-axis");
I did and it does not work, apparently only the bottom axis label dare 
to show up!
I 've checked in your code and saw nothing obvious.
Do you have the same behaviour?
Any idea where it comes from?

[Fxplot-users] Version 0.2.1 released

[Rafael de P. S. <ra...@rp...>]

Hi,

I just added release 0.2.1 of FXPlot at 
http://sourceforge.net/projects/fxplot

In this release a bug with the exporting to file dialog was fixed 
(thanks to Jean-Dominique) and support for FOX-1.6 brach was added (just 
define FOX_1_6).

I'll add some #ifdef's for the 1.6 branch, then in the new release you 
could just devine the directive FOX_1_6 and the things will work.

Yes, it is a bug. I fixed that, will be in the next release. Thank you 
for reporting.

Currently there is no support for this feature, but it should be not 
difficult to add. Unfortunatelly I have no time to do it right now. I 
can help if you want to implement it.

Not yet, and I think that this is not so easy to implement in an 
efficient way. I use double buffering to draw the plot, first the plot 
is drawn into a memory image and then into the window.

No, but this is very desirable. Again if you want to contribute on this...

[Fxplot-users] Re: Fxplot-users digest, Vol 1 #2 - 1 msg

[Jean-Dominique B. <jea...@fr...>]

Rafael,

got the right adress now...

I'm using FOX 1.5.13, not 1.4.x.
Following your advice, i replaced the old method with their=20
corresponding new version (FOX 1.5 and above) in the following two lines:
    FXString ext=3DFXPath::extension(file); // old version for FOX 1.4.x:=
=20
FXFile::extension(file);
    if(FXStat::exists(file)){   // old version for FOX 1.4.x:=20
if(FXFile::exists(file)){
Everything now compiles fine on VC7.0 with FOX1.5.13.
Moreover, i 've successfully compiled and run the curves.cpp sample file=20
you provide with FXPlot 0.2.0.
As this is a good example to start with using FXPlot, i should not have=20
much difficulties to use FXPlot in my application.

After having playing a bit with it, i've got few additional questions:

1) in the method given below:
long FXPlotBase::onSave(FXObject* obj,FXSelector sel,void* ptr){
    FXString file("Exporting Plot to File");
    FXFileDialog dlg(this,file);
    dlg.setFilename(name + ".png");
why is the png type set by default?
It does not work on my system as i did not compile the png lib (i got=20
jpeg anf gif support, not png). As a result, when i want to save an=20
image, it opens a dialog box with the png extension, whereas this=20
extension is not proposed in the corresponding drop-down liston the dialo=
g.

2) the behaviour of the zoom tool is basically to apply a magnification=20
factor around the picked point. Is there another zoom tool based on the=20
direct mouse selection of the rectangular region to be magnified?

3) once you have zoomed, it may be useful to be able to apply some=20
translation or pan (xy shift) to the graph, instead of going back to the=20
original image and zooming again at another place.
Is it possible to do that?

4) Is it possible to have some interaction (e.g. mouse selection) of=20
objects that are drawn (such as points and/or lines)?

Best regards,
Jean-Do

[Fxplot-users] Re: Problem using FXPlot2D

[Rafael de P. S. <ra...@rp...>]

Hi Jean,

Regargind the mail list, I think you sent the message for the wrong 
address, the correct is fxp...@li....

About your questions, which version of FOX are you using?
Currently only version 1.4.X is supported, appears that in new versions 
exists() and extension() have moved from the FXFile. I think the new 
version is FX::FXStat::exists() and FX::FXFileAssoc::extension().

Some time ago I have compiled it with VC7 with no problem.
Sory for the question, but have you included the FXPlot2D.h header in 
your file?
Please take a look at the file curves.cpp and check if you could 
generate an executable for it.

With the best wishes,
Rafael.
