problem with displaying x-axis date values

[Malad]

Hi,

I am having problem trying to format the x-axis value. I want the dates to be displayed verically in the dd-mm-yy format

When I use this:
DateTickUnit dateUnit = new DateTickUnit(DateTickUnit.DAY, 1, new java.text.SimpleDateFormat("dd/mm/yy"));
axis.setTickUnit(dateUnit);

the program compiles but throws a ServletException. The error msg says:

root cause

java.lang.NoSuchMethodError: com.jrefinery.chart.HorizontalDateAxis.setTickUnit(Lcom/jrefinery/chart/DateTickUnit;)V
at client.LineGraph.doPost(LineGraph.java:97)
....
.
.

and when I add this line:

axis.getTickLabelFormatter().applyPattern("dd-MMM-yyyy");

I get the following compilation error :

root cause

java.lang.NoSuchMethodError: com.jrefinery.chart.HorizontalDateAxis.setTickUnit(Lcom/jrefinery/chart/DateTickUnit;)V
at client.LineGraph.doPost(LineGraph.java:97)


What is even more baffling is when I say
axis.setAutoTickUnitSelection(true);

the date axis range from 7-Jan-2002 to 8-Jul-2002 .

My SQL query clearly states a different date range.
String frmDate = "01/06/2002";
String toDate = "30/06/2002";

Where is it getting the above dates from and what can I do to fix my problem? Your help is much appreciated.

Thanks

sorry! the compilation error that I get is :

LineGraph.java:97: cannot resolve symbol
symbol : method tickLabelFormatter ()
location: class com.jrefinery.chart.HorizontalDateAxis
axis.tickLabelFormatter().applyPattern("dd-MMM-yyyy");

Hi there!

Could someone throw me some pointers for the above mentioned problems?

I'd be very much appreciated.

Thanks.

There is no method tickLabelFormatter() in JFreeChart, so your compiler is correct to report an error.
