xDomain issue for multiData graph

[akkikumar72]

So, I am working on a multiData graph with latest 3 graphs in the chart.

 dataProp = {
      one: mockData,
      two: mockData2,
      three: mockData3,
    };

First graph ie. one is base graph and have around 30 datapoints(mockData) and rest around 22 datapoints(mockData2 & mockData3).
So, in my chart, it only show base graph taking all x-axis space and others just taking 80% of the spaces.

As in multiData we have multiple dataPoints. its hard to have xDomain for any specific graph data.

Any suggestion will be greatly appreciated.
