Re: [Plplot-devel] [Plplot-general] wxWidgets driver -- change thedefault blackbackground
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 *frame = new wx_PLplotwindow();
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;
}
/
//Plot
/
template< class WXWINDOW >
void Plot(wx_PLplotwindow *plotwindow)
{
wx_PLplotstream* pls = plotwindow->GetStream();
//render
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();
}

The only suggestion I have is the one I sent on my previous mail, that
was *not* to have
wxPLplotstream::Create
call
init()
and let the user do that on his application.
By looking at the samples, I believe they all call plinit() at start,
my complete test code is now
#include "wx/wxprec.h"
#include "wx/wx.h"
#include "wxPLplotwindow.h"
template< class WXWINDOW >
void Plot(wxPLplotwindow *plotwindow);
/
//wxAppPlot
/
class wxAppPlot : public wxApp
{
public:
virtual bool OnInit();
};
IMPLEMENT_APP(wxAppPlot)
bool wxAppPlot::OnInit()
{
wxPLplotwindow *frame = new wxPLplotwindow();
frame->Create(NULL, wxID_ANY, wxT("wxPLplot"),
wxDefaultPosition,
wxSize(900, 700));
frame->Show();
Plot(frame);
return true;
}
/
//Plot
/
template< class WXWINDOW >
void Plot(wxPLplotwindow *plotwindow)
{
wxPLplotstream* pls = plotwindow->GetStream();
pls->adv(0);
pls->scolbg(255, 255, 255);
pls->clear();
//render
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(8);
plenv(xmin, xmax, ymin, ymax, 0, 0);
pllab("x", "y", "Label");
plpoin(NSIZE, x, y, 46);
plotwindow->RenewPlot();
}

Re: [Plplot-devel] [Plplot-general] wxWidgets driver -- change the default blackbackground
Hi Pedro
The easiest way to do this at the moment is something like
wxPLplotstream* pls = plotwindow->GetStream();
pls->adv( 0 );
pls->scolbg(255, 255, 255);
pls->clear();
//rest of your plotting code
If you have multiple subpages then you will need to do this on each
page. Also if your subpages don't cover all the windows then you can
call the SetBackgroundColour method of wxPLplotwindow and this will
clear the whole window to the given colour initially.
Hope that helps. If not then let me know. I'm very open to better ways
to do this if you have suggestions.
