Octave + Gnuplot rendering image upside down

Question

I am displaying data using function imagesc(). If I set fltk as graphics_toolkit image is displayed correctly.

Can't post images directly(low reputation) https://i.stack.imgur.com/ARiwF.png

If I use gnuplot as plotting program image is rendered upside down. fltk is unusable for me because its window isn't responding while function in octave is running. I also tried plot sine and it was correct plotted through fltk and gnuplot too.

Answer 1

There are at least two workarounds:

• Use axis("xy") or axis("ij") to control the orientation of the y-axis, as decribed in the axis documentation

• Use set(gca, "ydir", "normal") or set(gca, "ydir", "reverse"), as decribed in the axes properties doc
