I want to plot a series of points, a plane and the intersection points with that plane using gnuplot. In order to do this, I created the following gnuplot script:
set title 'Homogeneous field with plane intersection'
set xlabel 'x'
set ylabel 'y'
set zlabel 'z'
set parametric
splot 'points.txt' with linespoints, 'intersectionPoints.txt' with points
pointtype 7 lc rgb 'red',
60 + 0 * u, u, v
The script produces the following plot:
Everything works fine, however the size of the parametric plane is way too small. How can I get gnuplot to automatically adjust the size of the plane to roughly match the dimensions of the rest of the plot?
