# Plot spines show in middle of graph

Hi. I am new to SageMath. I like what I see, thanks!

I ran into a tiny but annoying problem: I draw a `region_plot`

and it works very well, but the spines of the plot are drawn down the middle. I tried to make them go away using the standard `matplotlib`

capabilities but they will not disappear. Here is my code:

```
reset()
a,b,c,x,y = var('a b c x y')
from matplotlib import spines, axes
i = 16
p = region_plot(
tan(x^2 - y^2)>0,
(-i*pi,+i*pi), (-i*pi,+i*pi),
incol='green',outcol='lightblue',
)
p.matplotlib().axes[0].spines[['left', 'bottom']].set_position('zero')
p.matplotlib().axes[0].spines[['top', 'right']].set_visible(False)
p
```

I am using SageMath on - Ubuntu 22.04 installed in WSL - Notebook is VSCode notebook with vscode-Jupyter extension - Vscode version 1.80

The entire above code is run in a single cell

Thanks

I don't understand what do you mean by "spines", maybe the axes? You would like to remove axes?
