If you use a dataset with more than 10 x values, seems that the we don't correctly computed the bottom axis label width.
Can be reproduced using the following to generate a simple dataset:

import { DataGenerator } from '../utils/data_generators/data_generator';

const dg = new DataGenerator();
const data = dg.generateSimpleSeries();

...
<AreaSeries
    id={getSpecId('area')}
    xScaleType={ScaleType.Linear}
    yScaleType={ScaleType.Linear}
    xAccessor="x"
    yAccessors={['y']}
    data={data}
/>

The axis values are correct, but seems to be cutted off:
0, 5, 1, 1, 2, 2, 3, 3, 4, 4 instead of
0, 5, 10, 15, 20, 25, 30, 35, 40, 45
