Hello everyone,
I am barplot, But I need only barnames at few locations in the xaxis. Because my barnames are in years and they are 23. So overlap is happening if I give all the barnames. So I need to name few bars.

Please let me know how to do this.

thanking you in advance

You can do something like this:

IDL> barnames = StrTrim(Indgen(23)+1995)
IDL> print, barnames
1995 1996 1997 1998 1999 2000 2001
2002 2003 2004 2005 2006 2007 2008
2009 2010 2011 2012 2013 2014 2015
2016 2017
IDL> blanks = Indgen(10)*2+1
IDL> barnames[blanks] = ""
IDL> print, barnames
1995 1997 1999 2001 2003 2005
2007 2009 2011 2013 2015 2016 2017

Cheers,

David

Respected sir,

Whoops! Instead of this:

barnames[blanks] = ""

Use this:

barnames[blanks] = " "

Cheers,

David

There are no zeros in the ticks when I execute:

barnames = StrTrim(Indgen(23)+1995, 2) ;slightly changed from David's snippet
blanks = Indgen(11)*2+1 ;also slightly changed from David's snippet
barnames[blanks] = " "
cgbarplot, findgen(23), barnames=barnames

Are you sure you're using the latest and greatest version of the Coyote library?
