The data is then plotted on top of this image, which is very useful for annotations, computer vision, etc. Note that when plotting data, the y axis usually points up, but when looking at images, the y axis of the pixel coordinates points down instead. Thus, if the y axis extents ...
Here an existing image is given to gnuplot verbatim, and data to plot on top of it is interpreted by feedgnuplot as usual.flipyis useful here because usually the y axis points up, but when looking at images, this is usually reversed: the origin is the top-left pixel. ...
