Hello.
I want to plot the parametric function x(t) = t+log(t+1) y(t) = sqrt(t)+sin(t) from t=0 to t=2 in steps of dt = 0.2 using circles of radius 0.05 (instead of points) I searched for about 2 hours but could not find how to do this directly in gnuplot. I could create a data file and then plot that, but I want to plot the functions directly. Is there a way to do that in gnuplot? Thank you. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ gnuplot-info mailing list [hidden email] Membership management via: https://lists.sourceforge.net/lists/listinfo/gnuplot-info |

Several, but I think the one I show above is the easiest. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ gnuplot-info mailing list [hidden email] Membership management via: https://lists.sourceforge.net/lists/listinfo/gnuplot-info |
