column chart no show value no value in tooltip (role)

[marino signorelli]

I have a simple chart (column chart with only one column  with numbers )

I do not want to see the vertical axis with the scale of values,

and in the tooltip (role)  I want to see only the value of the horizontal axis (domain).

it's possible ?

exampe data='[ ["5d", 0], ["6d", 7], ["7d", 10], ["8d", 7], ["10d", 0], ["11d", 5], ["12d", 3] ]
