Phil
I believe there is stiil an issue with this solution
my sample worked because I had
plcol0(8);
that does the plot in brown color
if I try to plot in black color (on white bacground now) by doing
plcol0(0);
then I have no plot, since color 0 is now white
is there a way with this solution to define color 0 as black for the plot?
I tried to call
plscol0(0, 0, 0, 0);
as
wxPLplotstream* pls = plotwindow->GetStream();
pls->adv(0);
pls->scolbg(255, 255, 255);
pls->clear();
plscol0(0, 0, 0, 0);
but like this I have the default red on black again
for now, the way I was able to have the black on white background was to
replicate all the code
of
wxPLplotwindow
wxPLplotwindow
into new classes , giving them another name, commenting the init() call on
them and then
doing this code (note that the classes are renamed to wx_PLplotwindow and
wx_PLplotstream)
bool wxAppPlot::OnInit()
{
wx_PLplotwindow<wxFrame> *frame = new wx_PLplotwindow<wxFrame>();
frame->Create(NULL, wxID_ANY, wxT("wxPLplot"),
wxDefaultPosition,
wxSize(900, 700));
frame->Show();
//set background color (0) to white RGB(255,255,255)
//must be called before plinit()
plscolbg(255, 255, 255);
wx_PLplotstream* pls = frame->GetStream();
pls->init();
//change color (0) to black RGB(0, 0, 0)
//must be called after plinit()
plscol0(0, 0, 0, 0);
Plot(frame);
return true;
}

void Plot(wx_PLplotwindow<WXWINDOW> *plotwindow)
{
wx_PLplotstream* pls = plotwindow->GetStream();

const int NSIZE = 101;
PLFLT x[NSIZE], y[NSIZE];
PLFLT xmin = 0, xmax = 100, ymin = 0, ymax = 10;
for (int i = 0; i < NSIZE; i++)
{
x[i] = i;
y[i] = 5;
}
plschr(0, 1.0);
plcol0(0);
plenv(xmin, xmax, ymin, ymax, 0, 0);
pllab("x", "y", "Label");
plpoin(NSIZE, x, y, 46);
plotwindow->RenewPlot();
}
