The origin (point of 0,0) in gnuplot is always located on the bottom left corner with upward incrementing y value.
Is there a way to modify the orientation of the origin to top-left with y-axis incrementing from top to bottom like the coordinate system popularly used in imagings? I am using gnuplot to plot data file.
Any idea? Thanks in advance.
That’s quite simple. Use
then you should have the y-axis going from xmax up to 0. On one of my computers I saw that the x-axis was also reversed after this command. If this happens to you as well make sure to get the latest version of gnuplot.
