- Description
An instance of the Gnuplot class is a pipe to a running gnuplot. You can use write to send orders to It, or use some of the methods defined in this class to do It.
-
Inherit Pipe
Pipe
-
Method write
void module.Gnuplot.Gnuplot()->write(string what)
- Description
This method is just like the analog method in class Pipe, but adds a '\n' for convenience.
-
Method quit
void module.Gnuplot.Gnuplot()->quit()
- Description
Closes the running gnuplot.
-
Method plot
void module.Gnuplot.Gnuplot()->plot(string func)
- Description
Plots f(x). Example: plot( "sin(x)" );
-
Method parametricPlot
void module.Gnuplot.Gnuplot()->parametricPlot(string func)
- Description
When doing 2D parametric plots, the parameter is t. Example: to draw a circle, just do parametricPlot( " cos(t), sin(t) " );
-
Method splot
void module.Gnuplot.Gnuplot()->splot(string func)
- Description
Plots f(x,y). Example: plot("sin(x) * cos(y)") ;
-
Method parametricSplot
void module.Gnuplot.Gnuplot()->parametricSplot(string func)
- Description
When doing 3D parametric plots, the parameters are u and v.
-
Method surfaceSplot
void module.Gnuplot.Gnuplot()->surfaceSplot(string func)
- Description
Uses the pm3d option to draw surface maps.
-
Method set
void module.Gnuplot.Gnuplot()->set(string what)
- Description
Sets some property of gnuplot.
-
Method unset
void module.Gnuplot.Gnuplot()->unset(string what)
- Description
Unsets some property of gnuplot.
-
Method setGrid
void module.Gnuplot.Gnuplot()->setGrid()
- Description
Enables the grid.
-
Method unsetGrid
void module.Gnuplot.Gnuplot()->unsetGrid()
- Description
Disables the grid.
-
Method setParametric
void module.Gnuplot.Gnuplot()->setParametric()
- Description
Enables the parametric mode.
-
Method unsetParametric
void module.Gnuplot.Gnuplot()->unsetParametric()
- Description
Disables the parametric mode.
-
Method update
void module.Gnuplot.Gnuplot()->update()
- Description
Updates the screen
-
Method save2postscript
void module.Gnuplot.Gnuplot()->save2postscript(string filename)
- Description
Saves a postscript copy of the screen. This method has something similar to a bug: if your screen has a parametric plot on It, this doesn't work. In that case, please do setParametric() ; save2postscript() ; unsetParametric();
