trange

Syntax: set trange [tmin:tmax] The range of the parametric variable t is useful in three contexts. 1) In parametric mode plot commands it limits the range of sampling

   for both generating functions.  See `set parametric`, `set samples`.

2) In polar mode plot commands it limits or defines the acceptable

   range of the angular parameter theta during input.  Data points
   with theta value outside this range are excluded from the plot even
   if they would otherwise lie inside the plot boundary. See `polar`.

3) In plot or splot commands using 1-dimensional sampled data via

   the pseudofile "+".  See `sampling 1D`, `special-filenames`.
