Hi
I am trying to change the default black background color using the wxWidgets
driver
If using the SVG driver this can be done as explained here
https://sourceforge.net/p/plplot/mailman/message/2817799/
the trick being calling
plscolbg()
before
plinit();
like the sample code below marked "SVG Driver" does
However for the wxWidegts driver , it seems we do not do a call to
plinit();
but rather this is done inside the C++ stream initialization
>From the wxWidgets PLplot sample below
the
plinit();
is made inside
frame->Create(NULL, wxID_ANY, wxT("wxPLplot"));
so I don't find a way to call the plscolbg() function before
How can this be accomplished ?
I also tried to modify the default colors of the default palette
cmap0_default.pal
16
#000000
so that the first is white
this does work *but* only after the window is redrawn (it first shows the
default red on black);
this seems like a bug to me
Also, what's the call to increase the font size?
On the wxWidgets driver the font looks tiny
Thanks !
Sample code wxWidgets
bool wxAppPlot::OnInit()
{
wxPLplotwindow<wxFrame> *frame = new wxPLplotwindow<wxFrame>();
frame->Create(NULL, wxID_ANY, wxT("wxPLplot"));
frame->Show();
Plot(frame);
return true;
}

wxPLplotstream* pls = plotwindow->GetStream();

}
Sample code SVG driver
void atms_dwell_granu_t::plot()
{
//set SVG device and output file name
plsdev("svg");
plsfnam("atms_dwell_granu.svg");
//set background color (0) to white RGB(255,255,255)
//must be called before plinit()
plscolbg(255, 255, 255);
//initialize plplot
plinit();
//change color (0) to black RGB(0, 0, 0)
//must be called after plinit()
plscol0(0, 0, 0, 0);
