Steps to reproduce

check the YAxis:

domain={['dataMin', 'dataMax']}
allowDecimals={false}
tickCount={9}

it still shows decimals, which is something I can get around with specifying a tickFormatter.
it does not respect tickCount correctly, so, number of ticks change when tickCount is changed, but they are unevenly spaced and never equal to tickCount.

if I change this to:

domain={['dataMin', 'auto']}
allowDecimals={false}
tickCount={9}

then ticks are calculated correctly, evenly spaced and respect the tickCount, but the y axis does not start from dataMin anymore.

What is expected?

There should be some way of making tickCount work with provided domain.

What is actually happening?

When explicitly specifying the domain, ticks are unevenly spaced and do not respect tickCount
