Look to gnuplot web page. There are some front-ends / wrappers lists. It
would be useful to use an already existing API rather than developing your
own.


BTW, you could not use one of the existings, and add a possibity to draw
into a KDE widget? Or even a "KE Widget" terminal for gnuplot?

not GNUPlot, see FAQ --> rather KGnuplot

rather prefixed: kgnuplotLineStyle

That looks like reimplementation of gnuplot structure into you KDE. What
about just the similar thing as Octave does:
	wid->raw("set mxtics 5");

raw would do printf()+fflush()
