I have a 3d plot:

```julia
using Plots

x = [0,0,0,1,1,1,2,2,2]
y=[0,1,2,0,1,2,0,1,2]
z = 10*rand(9) .+ 2*collect(1:9)

plot(x,y,z, st=:surface,camera = (60,15))

```

axes intersect at:

How can I change it so:  
z and y on min z and max y. y and x at min y and min z

```julia
plot(x,y,z, st=:surface,camera = (60,15), yflip = true)

```

flips whole graph, not just axis, while axes are connected at the same points.

I’m not sure what you are trying to do, but I think you want to rotate the plot more, so that the axes go behind the plot. Just playing around in Pluto, I found that the plot would not update angles beyond `(0, 90)`. In the GIF below, I tried pushing the angle to `-10` or `100`:

Is that your issue?

Nope, I want to inverse Y axis:  
YZ intersection would be (z = 0, y = 2)  
YX intersection would be (y = 0, x = 0)

You want to change the origin of the axes?

Yes. Specifically of Y axis

So you want the axes to _ **not** _ intersect at the same point?

I want Y and X have origin in the same point (0,0,min(z))

Oh I see now! A nice scketch is worth a thousand words! Not sure you can do that if `yflip` does not work. have you tried flipping your data and the tick labels manually?

I could make data negative, and make ticks as strings (without minus). But this must be simplier.

```julia
x =- [0,0,0,1,1,1,2,2,2]
y= [0,1,2,0,1,2,0,1,2]
z = 10*rand(9) .+ 2*collect(1:9)

plot(x,y,z, st=:surface,camera = (85,15),xticks = ([-2,-1,0], [2,1,0]) )

```

This works, but I am disappointed.

How does one open a feature request? Without the ability to change where axes intersect, Julia decides that I don’t need to see the axes:

 ![p3_tfc_soln](https://global.discourse-cdn.com/julialang/original/3X/6/a/6ae29c72ed0bb2b56ed8b494abc2c19dcd7729a4.png)  
and after adding `camera=(-45, atand(1 / √2))`:  
 ![p3_tfc_soln](https://global.discourse-cdn.com/julialang/original/3X/d/7/d79cfdf37311d0702d38cfeeaaa998e015c07627.png)

Edit: Came up with a hack

```julia
function rotate_negative_45_degrees!(surface_plot)
    # The GR backend cannot properly display the axes if you decide to rotate
    # the camera -45 degrees. This wouldn't be so bad if it had a way of
    # manually setting the spine positions a la matplotlib, but it doesn't.

    # Swap the axis labels
    temp = surface_plot[1][:xaxis][:guide]
    xlabel!(surface_plot, surface_plot[1][:yaxis][:guide])
    ylabel!(surface_plot, temp)

    # Swap the ticks
    temp = xticks(surface_plot)[1]
    xticks!(surface_plot, yticks(surface_plot)[1])
    yticks!(surface_plot, temp)

    # Transform data appropriately
    xticks!(surface_plot, (xticks(surface_plot)[1][1], reverse(xticks(surface_plot)[1][2])))
    surface_plot[1][1][:z] = Surface(reverse(surface_plot[1][1][:z].surf', dims=2))
end

```
