2/21/2023 0 Comments Gnuplot set arrow![]() But it seems like there should be a better solution, so please let me know if you think of one. To see what's wrong with simply using the "front" option as a fix, replace the first line with: set arrow 1 from 0,0,0 to 0,0,1 lw 2 frontĮdit: I realized after posting that this can be done with multiplot. I'm using a fine mesh so that the effect is clearly visible. Is there a way to do that (i.e., manually set the order in which curves and other objects are drawn)? If not, does anyone have a good workaround? (The only one I can think of is to draw the arrow manually using lines, but I'd like to avoid that if possible.) The obvious solution is to split the function drawing the cone into two halves and make the arrow in front of one curve and behind the other. But, viewed in perspective, the arrow should be in front of the back half of the cone, and behind the front half of the cone. gnuplot version gnuplot 4.6 patchlevel 0 Click here for minimal script to generate this plot set title 'Top: plot with vectors arrowstyle 2, Bottom: explicit arrows' plot \ 'arrowstyle. If I add the "front" option to the arrow, it is displayed in front of the entire cone. By default, the arrow is displayed behind the entire cone. Arrows number from-to head type style set arrow 1 from 5,-0.5 to -5,0.5 head filled size screen 0. ![]() One of the most useful shortcut is to press space to set the focus of the command window from the plot window. The only problem is that I can't figure out how to fit the arrow correctly into the 3D perspective of the picture. I tried to be as simple as possible to understand the main features. ![]() But now, one part of the arrow is hidden completely behind the surface and doesn't shine. However it affects arrows drawn with the vectors plotting style: set hidden3d splot sqrt (x2 y2), '< echo '0 0 0 0 0 1'' with vectors. I'm using gnuplot to draw a cone with an arrow pointing upwards through the cone's axis of symmetry. To hide lines partially, one can usually use set hidden3d, but that does not affect arrows placed with set arrow. ![]()
