How to style Y axis to show the full value of label from hovermode='y'?

Could you please suggest styling properties for unhiding label from hovermode=‘y’?

Found a solution to my question. Setting a non-None yaxis title would give the space between the left edge of plot and y-axis, to allow display of the y label:

e.g.
fig.update_layout(yaxis=dict(title=“xxxx”))
