GTL barchart question

Hi!

I would like to create a graph as follows using barchart tags instead of needleplot.

Is there anyway to keep the reference lines as they are? I'm using SAS 9.2M3.

Thank you in advance for any help!

Regards,

Paolo

Re: GTL barchart question

Note some items for this graph:

  • This should work with SAS 9.2(TS2M3).
  • The reference lines need to have the formatted values.  hence the eval(put).  This is due to a bug / lack of feature where if you are using user defined formats, the reference line with constant value (not from column) does not have a format.
  • You can use the same attributes for the reference lines as the grid lines to make them all look consistent.
  • You cannot do this with SGPLOT as you cannot overlay VBAR statements with different category variables.  But with SAS 9.3, you can do this using the VBARPARM statements.
