How to remove the label like "x" or "y"?

For example, 3D Line Plot of Brownian Motion


The axis label for ā€œxā€, ā€œyā€ and ā€œzā€ are shown in the graph. Is it possible to hide these? It does make much sense when the labels are categorical as the axis does not matter much but the label explains better. I know how to add titles to the axis but sometimes the title text can collide with ā€œxā€ or ā€œyā€ text.
