Label question

Hi,

I would like to set the xAxis's label so that it shows a range of time rather than just its datavalue (CDateTime format).

xAxis.getLabel().setCaption(????);

I need to access the CDateTime value in the label and have the label shows also an interval of time (possibly 1 hour) before the value. (I can get the previous time with CDateTime pv=value.backward(12, interval); )

So I need to know how to access the CDateTime value from the label and modify the label's caption.

Hi MC,

You should be able to grab the current label value with the following script function and code:

function beforeDrawAxisLabel( axis, label, icsc )
{
label.getCaption().getValue();
}

Let me know if I'm not understanding your question correctly.

I don't think that works. I am using BIRT Chart Engine to create a histogram view rather than a report. The only way to do so using BIRT is by starting with a bargraph and making it look like a histogram. The label that I am getting is a set of x-axis scales (in CDateTime format), so it is something like 07/ 28 05:00, 7/28 10:00, 7/28 15:00, 7/28 20:00. I have already gotten the frequencies for the time range, and I would like to make it look like a histogram rather than a bar graph. I can either set the scales' label to a set of ranges (07/ 28 00:00 - 07/ 28 05:00, 07/ 28 05:00 - 7/28 10:00, etc) or insert a beginning scale label with no value and shift all the bars to the left. 
 
Code snippet: 
 
xAxis = chart.getPrimaryBaseAxes()[0]; 
xAxis.getLabel().getCaption().getFont().setRotation(45); 
// xAxis.setLabelPosition(Position.RIGHT_LITERAL); //error 
xAxis.setGapWidth(10); //?? 
xAxis.getTitle().getCaption().setValue("Time"); 
xAxis.getTitle().getCaption().setColor(ColorDefinitionImpl.CREAM()); 
xAxis.getTitle().setVisible(true); 
String k=xAxis.getLabel().getCaption().getValue(); 
System.out.println("Value: "+k); -->print out "Value: " no k value?
