line graph w/ selected labels and tick marks

Hi -

I want to create a line graph that only displays certain labels and
tick marks on the x-axis.  For example, if I had the below data set
and code and I only want to display lable and tick marks for 1, 3, 5
and 7 how could I do it?

String[] xAxisLabels= { "1", "2", "3", "4", "5", "6", "7"};
DataSeries dataSeries = new DataSeries( xAxisLabels, xAxisTitle,
yAxisTitle, title );

double[][] data= new double[][]{ { 250, 45, -36, 66, 145, 80, 55  } };

...
...
...
		 
axisProperties.getXAxisProperties().setShowTicks(
AxisTypeProperties.TICKS_ONLY_WITH_LABELS );

// null is for no legend 
axisChart= new AxisChart( dataSeries, chartProperties, axisProperties,
null, defWidth, defHeight );

I tried populating the xAxisLabels with empty string, but I get "Zero
length string passed to TextLayout constructor." when I try to render
the graph.

Thanks - Silas
