hallo, everyone, is it possbile to plot two functions with seperate ranges in one plot? for example, y=2*x*x, x =[0,2], y=-2x*x+16, x=[2,4]. Anyone has an idea? -- View this message in context: http://www.nabble.com/plot-range-tp17079869p17079869.html Sent from the Gnuplot - User mailing list archive at Nabble.com. |

plot x<=2 ? 2*x*x : -2*x*x+16 or plot x<=2 ? 2*x*x : 0/0 , x>=2 ? -2*x*x+16 : 0/0 for more information see the manual http://www.gnuplot.info/docs/gnuplot.html ('gnuplot' - 'expressions' - 'operators' - 'ternary') or type help ternary at the gnuplot prompt. > hallo, everyone, > > is it possbile to plot two functions with seperate > ranges in one plot? for example, > y=2*x*x, x =[0,2], y=-2x*x+16, x=[2,4]. > Anyone has an idea? -- View this message in context: http://www.nabble.com/plot-range-tp17079869p17080131.html Sent from the Gnuplot - User mailing list archive at Nabble.com. |

hello, thanks for your answer. At first it works. But the plot is one function, it means i can not plot them with two colors or with two titles. Do your have any suggestion for this?

Dear all, I have an esthetic problem... I have basically two curves which are more or less the same.. I want to plot them in a same graph with a dashed line..of two different colors...one color for each curve ... so the best would be to have dashed lines which are a bit shifted (ideally in quadrature..) is that possible??? can we set that? or do you have an idea of another trick? thanks a lot, Julien |

As far as i know, dashed line with color is difficult. It may be possible with postscript. But i have never tried it.

Hallo, Thomas, Is it possible to plot a straight line like x=3, 1<y<2, without using "set arrow"? -- View this message in context: http://www.nabble.com/plot-range-tp17079869p17226524.html Sent from the Gnuplot - User mailing list archive at Nabble.com. |

> Is it possible to plot a straight line like x=3, 1<y<2, without using "set arrow"? yes, in parametric plotting mode, see 'help parametric' but then all of your functions need to be specified as a pair of x(t),y(t)-functions, e.g.: instead of: set xrange [-pi:pi] plot sin(x) it would be: set parametric set trange [0:1] f(x)=x*2.*pi-pi ; # just for convenience plot f(t),sin(f(t)) plus a vertical line (x=2, -0.7<=y<=0.5): plot f(t),sin(f(t)), 2.,t*1.2-0.7 -- View this message in context: http://www.nabble.com/plot-range-tp17079869p17230077.html Sent from the Gnuplot - User mailing list archive at Nabble.com. |

> Is it possible to plot a straight line like x=3, 1<y<2, without using "set arrow"? gnuplot is able to plot functions and data. a vertical line isn't a function, but it may be plotted by giving its two endpoints: ------------------------------------------------------------ set xrange [-pi:pi] set yrange [-1.1:1.1] # function plus # 3 lines: # from 3.0,-0.5 to 3.0,1.0 # from 2.0,-0.8 to 2.0,0.9 # from -1.0,-1.0 to -1.0,1.0 plot sin(x), "-" with lines 3.0 -0.5 3.0 1.0 2.0 -0.8 2.0 0.9 -1.0 -1.0 -1.0 1.0 e ------------------------------------------------------------ -- View this message in context: http://www.nabble.com/plot-range-tp17079869p17237917.html Sent from the Gnuplot - User mailing list archive at Nabble.com. |
