hi Guys,  
I am trying to use Plots.plot to save images in REPL on ubuntu. However it always save the picture upside down even if I have not do anything on the image yet.  
Please help.

julia Version 1.1.1 (2019-05-16)

using Plots,Images  
backend()  
#Plots.GRBackend()  
pic=Images.load(“image\_orig.png”);  
Plots.plot(pic);  
Plots.savefig(“myplot\_test.png”)  
#open the picture of myplot\_test.png in browser, the pic is upside down

I’m not very familiar with Plots.jl but try setting `yflip = true`, it’s quite common for plotting packages to put (0,0) on the top left corner instead of the bottom left.

Thanks.

however, it does not help for both yflip = true and false

Plots.plot(pic, yflip = true)

#still upside down

Plots.plot(pic, yflip = false)

#still upside down

This works fine on my Windows 10 computer. I have not used this package before, but I just added `Images` and `ImageMagick`, and get:

If I use `pyplot` as backend while plotting, I get:

If I change and use backend `gr()` instead, I get exactly the same result.

NB: this also works with `*.png` files on my computer.

I’m facing a similar problem. It seems that image plotting won’t flip the y axis no matter how you put it. I’ve managed to go around that by reversing the array itself: `plot(img[end:-1:begin,:])` but of course that leaves now the y-ticks in the wrong order.
