Time Series - Date gets \'repeated\'

[gzsoham]

 n time series chart, where time period is 'day', if the min and the max dates in the horizontal axis is not further apart same day is printed (different time). Let me explain, say the min and max dates are 20 Apr 2010 and 21 Apr 2010. So the horizontal axis prints 20 Apr 00:00, 20 Apr 04:00, 20 Apr 08:00, ......, 21 Apr 00:00. I don't want to print 20 Apr twice. Actutally my 'time axis tick label mask' is set to 'dd-MMM-yy'. Hence the horizontal axis has no time info and it looks odd. Please see attachment. How can I make sure the same day is not repeated?

Use HH:mm as mask and print the date as title or in another location.  Having the date printed only for the first tick would require customizing JFreeChart as I don't think there's built-in support for something like that.

Hi Lucian,

I need to print the date in the x-axis in the format 'dd-MMM-yy'. So I guess, as you suggested, I need to customize JFreeChart. How can one do that? Do you have an example?

 

Thanks,

I don't have an example.  Get the JFreeChart sources, find the place where tick labels are generated and change the code to do what you want.
