Finally I think that's may be interesting for you the other bug in my code.
In wxPlplotDemo.cpp you have to replace constructor with this new
constructor ond plplot crash :
//! Constructor of our custom frame, where the Menu is created and a
// a wxPLplotwindow is inserted into the frame. We plot some easy functions
// just to show how it works. wxPLplotwindow takes care of all the setup
// for the use of PLplot library.
//
MyFrame::MyFrame( const wxString& title ) : wxFrame( NULL, wxID_ANY, title )
{
bgcolor = false;
// add menu
wxMenu *fileMenu = new wxMenu;
fileMenu->Append( wxPLplotDemo_BGColor, _T( "&Change background
color...\tAlt-C" ), _T( "Change background color" ) );
fileMenu->Append( wxPLplotDemo_About, _T( "&About...\tF1" ), _T(
"Show about dialog" ) );
fileMenu->Append( wxPLplotDemo_Quit, _T( "E&xit\tAlt-X" ), _T(
"Quit this program" ) );
wxMenuBar *menuBar = new wxMenuBar();
menuBar->Append( fileMenu, _T( "&File" ) );
SetMenuBar( menuBar );
SetIcon( wxIcon( graph ) );
// add the wxPLplot
wxPanel * panel = new wxPanel( this );
wxBoxSizer* box = new wxBoxSizer( wxVERTICAL );
plotwindow = new MyPlotwindow( this, panel, -1, wxDefaultPosition,
wxDefaultSize, wxWANTS_CHARS,
#if wxUSE_GRAPHICS_CONTEXT
wxPLPLOT_BACKEND_GC | wxPLPLOT_DRAW_TEXT );
#else
wxPLPLOT_BACKEND_AGG | wxPLPLOT_DRAW_TEXT );
