i attached the file which i am working for the layout.

Any example is very helpful

Thanks

Hi All,

My template code is as follows, not working properly

proc template;

define statgraph Forest;

dynamic _show_bands;

begingraph /designwidth=1000px designheight=600px;;

entrytitle halign=left "Company Name" halign=right "Study Phase"/ pad=(bottom=5px);

entrytitle halign=left "Drug Name" halign=right "Detailed Study information"/pad=(bottom=5px);

entrytitle "Table 1"/ pad=(bottom=5 px);

entrytitle "Duration of Survival by Overall Survival Status"/ pad=(bottom=5px);

entrytitle "Randomized Patients"/ pad=(bottom=5px);

entrytitle " "/ pad=(bottom=5px);

entrytitle halign=left "Treatment Group I Treatment Group II"/pad=(bottom=0px);

entrytitle halign=left "-------------------------------------- ---------------------------------------"/pad=(bottom=0px);

layout lattice / columns=8 columngutter=0 columnweights=(0.21 0.09 0.4 0.15 0.4 0.15 0.15 0.35);

/*--Column headers--*/

sidebar / align=top;

layout lattice / rows=2 columns=8 columnweights=(0.21 0.09 0.4 0.15 0.4 0.15 0.15 0.35);

entry textattrs=(size=8) halign=left "Baseline Risk Factor";

entry textattrs=(size=8) "Median (95%CI) mo";

entry " Event";

entry halign=right textattrs=(size=6) " ";

entry " ";

endlayout;

endsidebar;


and in log:

35143 - Forest plot has an example of creating a forest plot.

What do you mean "not working properly"? Error messages? No output? Unexpected output?

Thank you ballardw,

I adopted from the above mentioned paper.. but my layout is bit different that where i struck

Thanks

Hi Ballardw,

Working!!! no error message on the log, but output is not reflecting the layout what i required(attached)


and in log:

NOTE: COLUMNWEIGHTS=(0.21 0.09 0.4 0.15 0.4 0.15 0.15 0.35) is invalid. The default will be used.

Thanks

At SAS 9.2, columns weights should add up to 1.0.  For later releases, the sum of the weights is normalized automatically.

There are many examples on Graphically Speaking for Forest plots, both SAS 9.3 and 9.2:

http://blogs.sas.com/content/graphicallyspeaking/2013/01/06/forest-plot-with-sas-9-3/

It is easier to help if you attach the full working code with data.

Thank you Sanjay!!!

I am working on one your forest plot example. i am just trying to achieve different layout which i attached in my first post.

i got unexpected plot,

the following is sample data and code

Please attach your original SAS program file.  Cutting and pasting from here is messing up the input section of your code.

Jay54

There are a few issues with your code.  I had to simplify the input statement as your inline formatting with the & modifiers were not working.  I simplified the template so all the required values are displayed in 3 columns, one for the Subgroups, one for the values and one for the odds ratio graph.  You can add back the header as appropriate.

Hi Sanjay,

Thank so much for your time. I tried with my values but i got hard to fit in it. I dont know how to get the label part fix(control group ,placebo group)

find the sample code , data and layout style.

Thanks

Sam

The header is separately customized in the SideBar.  You will have to size the header cells as you need to get the headers in the right places.

Hi Sanjay,

i am exploring more on forest plot. I am considering few examples from your forum

http://blogs.sas.com/content/graphicallyspeaking/?s=forest+plot

Example :Figure 12.3:  SAS 9.3 Forest Plot:

i would like to achieve this kind of plot by using proc template , your example using proc sgplot

i am stumped with it!!!

any help is greatly helpful for learner like me !!!


Thanks

Sam

You will need to provide a bit more information on what aspect you are stumped with.  Note: A link to the full program for the graph is provided at the bottom of the article.  The program already uses GTL and not SGPLOT.

Hi Sanjay,

Thank you for your quick response !!!

this is link:

http://blogs.sas.com/content/graphicallyspeaking/files/2012/02/Full-SAS-93-Code.txt

this code is with GTL and proc sgplot

But i would like to achieve the same plot with

GTL+ proc sgrender

2)And for Overall , how do we get the symbol=diamondfilled?

Thanks

Sam
