Set value to the lowerMargin, upperMargin property of X Axis. This is kotlin code:

    val dateAxis = DateAxis("Time")
    dateAxis.lowerMargin = 0.05
    dateAxis.lowerMargin = 0.05

And this is the result: [enter image description here]

To Add margin to Chart we can add Padding 

public void addMargin(JFreeChart jChart){
      RectangleInsets chartRectangle = new RectangleInsets(28F,30F,30F,30F);
      //RectangleInsets chartRectangle = new RectangleInsets(TOP,LEFT,BOTTOM,RIGHT);
      jChart.setPadding(chartRectangle);
}

To align the header to Left set horizontal alignment to Chart title

public void alignChartTitle(JFreeChart jChart){
      jChart.getTitle().setHorizontalAlignment(HorizontalAlignment.LEFT);
}
