horizontal bars doesn't start at 0

[liatcohen]

When I use bar chart on horizontal mode, the zero is not at the start.
(for example, the red bar is 30 but it only shows 25):

It doesn't happen when horizontalBars=false.

this is my code:

<ChartistGraph
    data={{
        labels: ['Yes', 'No', 'Maybe'],
        series: [30, 10, 5]
    }}
    type="Bar"
    options={{
        istributeSeries: true,
        horizontalBars: true,
    }}
/>

Have any idea how to fix it?

Thanks
