enabled to specify domain

Abstract

This p-r enabled to specify domain by JSX.

e.g.

<LineChart
  legend={true}
  data={lineData}
  width='100%'
  height={400}
  viewBoxObject={{
    x: 0,
    y: 0,
    width: 500,
    height: 400
  }}
  title="Line Chart"
  yAxisLabel="Altitude"
  xAxisLabel="Elapsed Time (sec)"
  domain={{x: [,10], y: [-10,]}} // <= this line!!!
  gridHorizontal={true}
/>

Now the domains are depends on only data, though the range of domain is very important to display whole trends and current version hides whole data range.
