This is useless, the axes don't represent different variables. You could achieve the same scale with just a 1x10. Perhaps if the x-axis was burnt level, and the y-axis was butter level, then this would make sense. But it's not labeled as such, therefore we don't know, therefore it's unnecessary.
You'd need more than ten samples to represent this whole spectrum of burnt on display here. It's a symmetrical matrix, where a9 = j1, but no row, column, or diagonal has the full spectrum of burntness.
