I'm trying to create a marker line on a datetime X axis, but the line is
not appearing. I create the X axis with the following code:
AxisImpl xAxisPrimary = (AxisImpl) cwaBar.getPrimaryBaseAxes()[0];
xAxisPrimary.setType(AxisType.DATE_TIME_LITERAL);
xAxisPrimary.setCategoryAxis(true);
Then set the data:
DateTimeDataSet dateTimeValues = DateTimeDataSetImpl.create(new
CDateTime[] { new CDateTime(2005, 1, 1), new CDateTime(2005, 1, 2), new
CDateTime(2005, 1, 3) });
Series dateTimeSeries = SeriesImpl.create();
dateTimeSeries.setDataSet(dateTimeValues);
Then finally, I attempt to create the marker with a CDateTime as the input:
MarkerLineImpl.create(xAxisPrimary, DateTimeDataElementImpl.create(new
CDateTime(2005, 1, 2)));
No marker line appears, however. If I omit setting the axis type to
DATE_TIME_LITERAL, then I can set the marker by passing in the integer
index of the date in the series. But then I lose the ability to format the
date labels below the axis.
Is there something I'm forgetting to do? Thanks for your help.

Hi Patrick,
Did you add the MarkerLine into the axis?
E.g. MarkerLine ml = MarkerLineImpl.create(xAxisPrimary,
DateTimeDataElementImpl.create(new CDateTime(2005, 1, 2)));
xAxisPrimary.getMarkerLines( ).add( ml );
Cheers.
Regards,
Nina
