How to use multiple interval in single x-axis in a chart by Rana_Hasan

I want to use multiple interval in a single chart. e. I have created a report where date in the X-axis and values are in series in Y-axis. I hve passed only one parameter(Year) in my reoprt. It is working properly when the interval is auto. Now If I want to select the parameter, Year as 2012 and then I want to display the x-axis label as per below:

1-Jan-2012, 31-Jan -2012, 1-feb-2012, 28-Feb-2012 etc.

But I am not able to do that. I was trying to set the interval 30 Days but the result is not expected.
