Is it possible to sort an array with the smallest values on the bottom left and the highest on the top right?

For example :

I've this array :

```
[[-1.  1.  1.]
 [ 1.  1.  1.]
 [ 1.  1.  1.]
 [ 1.  1.  1.]
 [ 1.  1.  1.]
 [-1.  1.  1.]]

```

the sort would be like

```
[[1.  1.  1.]
 [ 1.  1.  1.]
 [ 1.  1.  1.]
 [ 1.  1.  1.]
 [-1.  1.  1.]
 [-1.  1.  1.]]

```

An other example :

```
[[-1.  1.  1.]
 [ 1.  1.  1.]
 [ 1.  1.  1.]
 [ 4.  3.  1.]
 [ 1.  1.  1.]
 [-1.  1.  1.]]

```

Would be :

```
[[ 1.  1.  4.]
 [ 1.  1.  3.]
 [ 1.  1.  1.]
 [ 1.  1.  1.]
 [-1.  1.  1.]
 [-1.  1.  1.]]

```

I Tried Numpy sort :

```
MyArray.sort()

```

But it seems not ordering this way.
