@indxx,

The range of charts in the stockchart is automatically calculated based on data being passed to navigator. To start the range of stockchart from first datapoint, you can set the minimum property of axisX in navigator to first datapoint as shown in the code snippet below.

navigator: {
     axisX:{
         minimum: new Date(2018,0,1)
     }
}

Kindly take a look at this JSFiddle for working code.
