Detailed Description

template<class T>
class Gnuplot< T >

Open a Gnuplot window and always show last n values of arbitrary defined channels. T can be std::string or int or anything else supports the << of streams. (It is used as name for a channel.)
Examples:

example.cpp.

void hide (  const T &  channel  )  [inline]
 

switch showing of this channel off Definition at line 175 of file gnuplot.h.

void hide_all (   )  [inline]
 

switch showing all channels off Definition at line 186 of file gnuplot.h.

void plot (   )  [inline]
 

make gnuplot plot content of data buffers Definition at line 232 of file gnuplot.h.

void plot (  int  start,
int  end
)  [inline]
 

make gnuplot plot selected content of data buffers Definition at line 205 of file gnuplot.h.

void plotXY (  const T &  x,
const T &  y
)  [inline]
 

make gnuplot XY plot content of x against y data buffers Definition at line 288 of file gnuplot.h.

void plotXY (  const T *  x,
const T *  y,
int  size
)  [inline]
 

make gnuplot XY plot content of x against y data buffers use it as follow: 

	T x[]={a,b,c};
	T y[]={x,y,z};
	plotXY(x,y,3);
Definition at line 256 of file gnuplot.h.

void printToFile (  const std::string  name = "",
const std::string  ext = ".log"
)  [inline]
 

save content of all data buffers in files ( file names are: name + channel_name + ext ) Definition at line 294 of file gnuplot.h.

void putData (  const T &  channel,
double  data
)  [inline]
 

add new data value to buffer for channel. if channel not exists nothing happens. So you can select channels in your program by commenting out the addChannel() call
