Remove separation between bar and axis line in JFreeChart

Is it possible to remove the distance between the bar and the axis line in a JFreeChart bar chart?

I have produced a bar chart that looks like (A), but I would like it to look like (B), i.e. without any separation between the bar and the (darker) axis line. The axis line is configured as:

    plot.getDomainAxis().setAxisLinePaint(new Color(0x333333));
    plot.getDomainAxis().setAxisLineStroke(new BasicStroke(1.0f));

I couldn't find the relevant setting for this purpose.

(A) actual and (B) intended chart

Edit: the demo chart at BarRenderer javadoc, also shows the same issue.

That space is called axis offset. The StandardChartTheme applies an axisOffset of 4px.

In order to remove the axis offset configure:

CategoryPlot plot = chart.getCategoryPlot();
plot.setAxisOffset(new RectangleInsets(0, 0, 0, 0));

The axis offset can also be configured at the theme level: StandardChartTheme.setAxisOffset
