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
