Oh, FYI, that's with version 4.2 on Windows.

when there is a row with a 0 in my dataset and I want to use logscale, I get an error: "range must be greater than 0 for log scale". I can specify the range myself, of course, but it would be better if the above were a warning instead and the range were set by the smallest non0 entry. |

Hi. I think you misunderstood my question. I dont want it to rotate in slow motion but to draw the graph in slow speed. For example, sin(x) in 2D plot, I want to see the sin(x) itself being drawn. Meaning at the start of the plot, the plot is empty and as time goes by, sin(x) will be drawn slowly. Is that possible to do in gnuplot? -- View this message in context: http://www.nabble.com/slow-motion-curve-tf3684500.html#a10316397 Sent from the Gnuplot - User mailing list archive at Nabble.com. |

You can't, short of modifying the source code. That's simply not what 'table' is meant to do, in its existing implementation. "table" outputs data ready to be read back into gnuplot. No more, no less. |

Only indirectly, if you make the range of the plot parametrizable (e.g. use parametric mode and manipule t range), and then animate the parameter like it's done in 'animate.dem'. |

Hi, I want to place an arrow in a graph while using "pm3d map" mode. And I do, but the "map" is placed above the arrow. E.g. in this script, ... set xlabel '$x$~[m]' set arrow from 0,312.5,615.15 to 1,312.5,615.5 set pm3d map splot 'Txt_s1_cos.dat' t '' Any idea about how to draw the arrow after the "map"? Thanks in advance. Regards, Diego Villuendas |

If I get you right, you desire a rotational solid and you want it to be drawn automatically, if you provide only the mathematical function for the borderline. gnuplot is only a plotting programme, not able to to the calculations needed for a rather complex gemometrical thing like a rotational solid. You might "cut" the solid into slices, so that you get a bunch of circles, but that won't result in a surface. If you insist in using gnuplot for your task, I would suggest, that you use an external programme, which somehow calculates the borderline points of the rotational solid in 3D coordinates and writes it to a tabular in a file. Then you could use gnuplot for plotting something similar to this: http://gnuplot.sourceforge.net/demo_4.2/surface1.19.png (see the demos for more details) Since we're touching the borders of gnuplots facilities with this, it may be better to use another (commercial) programme, e.g. maple or matlab.

Hola, I need >>also<< tabular output of my data reading from external files. The command set term table yields in a very poor output, each variable separately. How can I get a rectangular table suitable for printing in the form x1 y11 y12 y13 .. x2 y21 y22 y23 .. x3 y31 y32 y33 .. .. ................. ??? Thanks in advance. By the way: I use GNUPLOT in many ways and use it with my students. Wolf-Rainer Novender |

Seems a bit complicated...=20 The purpose of doing that is that i need a picture to show the surface it makes. After that we will add another function and try to calculate the volume that intersect the 2 functions. I think it will be hard to do like you show me.

It does --- it's just a bit harder to see. But if you insist on a round outline: set parametric set urange [0:5] set vrange [0:2*pi] splot u*cos(v), u*sin(v), u**2 |

Hi, I just installed gnuplot using Fink under mac OX 10.4.9, but the tab completion doesn't work. Do you know any way to fix it? saludos-greetings Dr. Bernardo Mendoza | email: Centro de Investigaciones en Optica| bm...@ci...

Hi, i need to plot a function and make it rotate around an axis in a 3D. Example: I have the function f(x)=x^2 and i need to rotate it around the y axis. Is there a way to do that with Gnuplot?

Not quite.

You have to run pgnuplot instead of wgnuplot here. That's what it
exists for.

Hi, This works in C:
Open the pipe to gnuplot:
fp = popen("gnuplot","w");
Send whatever commands you want:
fprintf(fp,"set data style lines\n");
Flush the pipe:
fflush(fp);
Close the pipe:
fclose(fp);
Hope this helps,
Gavin.
how do I pass a comment e.g. plot sin(x) to gnuplot from visual c++?
I have tried to use fprintf but it doesn't work?
Any idea anyone?
Thanks in advance!

hi.
I have manage to plot the sin(x) graph but it only show itself for a less
than a second.
How do I get the graph to show longer or permanently until the 'x' button
(exit) is clicked?
Here is my codes:
if ((pid > 0) && (cfile > 0))
{
printf("Open file suceeded!\n");
system("wgnuplot.exe command.txt");
_pclose(pid);
}
where cfile is the pointer to command.txt, which is my commands
and pid is the pointer to wgnuplot
