How to print a duration on Y-axis

Hi,

Currently, I'm using a Bar-Chart in witch I want to print a duration in the Y-axis.
The duration is in seconds and I want to apply a pattern on it, like this :
what I have -> what I want to be printed
235380 sec -> 65h 23min
3456 sec -> 57min 36sec
...

Is there a DurationAxis like the DateAxis ?
Is it possible to apply a pattern on the values of NumberAxis ?

P.S. : it's for a rush-work !!

You need to create a subclass of Java's NumberFormat that can convert your values (in seconds) into a string in the form "XXh YYm ZZsec".

I have just overloaded the format method of my subclass.
And that work !!

It's a good tip !!

Hi,

I create a subclass of Java's NumberFormat as you said and i try to apply this new format to my Chart with this code :

Code: Select all

NumberAxis numberAxis = new NumberAxis("CPU"); 
numberAxis.setTickUnit(new NumberTickUnit(1, new DurationFormat())) ;

or this :

Code: Select all

NumberAxis numberAxis = new NumberAxis("CPU"); 
numberAxis.setNumberFormatOverride(new DurationFormat());

but that's doesn't work.

Can you help me please ?

The code you posted will make JFreeChart use your DurationFormat class...what happens inside DurationFormat, I do not know.

Thanks for your response.

But my class DurationFormat works well out of JFreeChart.
I don't understand what happens.

This code works :

Code: Select all

        NumberAxis numberAxis = (NumberAxis) xyplot.getRangeAxis() ;
        numberAxis.setNumberFormatOverride(new DurationFormat());
        numberAxis.setLabel("CPU") ;

Thanks a lot.

Hi,

Now, i try to generate tooltip for my Time Series Chart using my format DurationFormat.

This is my code :

Code: Select all

XYLineAndShapeRenderer xylineandshaperenderer = (XYLineAndShapeRenderer)xyplot.getRenderer();
xylineandshaperenderer.setBaseShapesVisible(true);
xylineandshaperenderer.setToolTipGenerator(new StandardXYToolTipGenerator("CPU",new SimpleDateFormat("MMM-yyyy"),new DurationFormat()));

It doesn't work because only "CPU" appears in tooltip.

If i use this code :

Code: Select all

xylineandshaperenderer.setToolTipGenerator(StandardXYToolTipGenerator.getTimeSeriesInstance());

tooltip is generated but of course without my format.

Can you tell me whats' wrong in my code please ?
