Numbers show in star (*) in proc sgrender

Coffecat — Tue, 21 Jan 2020 00:35:21 GMT

Hi guys,

When I was using proc template and sgrender to get a forest plot. The statistic numbers round themself or show as a star(*) if the number is very large. As you can see in attached file.

Any thoughts?

Thanks,

Ray

The single most common cause of such a display I have found is specifying a format that displays too few characters for the value.

If you run this code the log will display an * as you mention:

data example;
   x=10;
   put x= f1.;
run;

The reason is there is no way for a value such as 10 or greater to be displayed with a single character (unless you go to HEX and then you have a limit of 16 base 10). Values less than 10 can be rounded to a single digit in some fashion but no way for larger.

So you likely need to change the format you are using but I can't suggest one without knowing the ranges of values and what you would like to display.

If you share your template or sgrender code we might suggest where to make a format change.

Thank you for your help. I post my dataset and code below. I used 8.3 format for my dataset(all those numeric variables).

Here is my code. Problem column is the 4,5,6 and 7th column as I comment below.

roc template;
define statgraph Ray;

Specify a VALUEFORMAT= options for variables to control appearance such as

***********4th Column*****************;
layout overlay / x2axisopts=(display=none offsetmin=0.25 offsetmax=0.25 )
yaxisopts=(reverse=true display=none) walldisplay=none;

axistable y=subgroup value=HazardRatio valueformat=6.4 ;
endlayout;

to display the Hazard ration with 6 print positions and 4 decimals.

If you aren't sure what format you want you might try BEST6. for all the problem columns to see what gets displayed and adjust as desired.

Thank you so much!!! That is the right solution. One more question, if I do not specify the format, is the default format show only one character in the scenario?

After applied the valueformat=best6. , numbers show in correct format, however, it misses the format I use for null values as showed in proc sgrender (format probchisq hazardratio hrlowercl hruppercl misblank.;) Does the best6. override my customized "misblank," format? I have no idea now how to fix this.

I figured out... I can use misblank6.2 to do this right.
