GRADAR Problem

Harris — Wed, 19 Sep 2012 09:16:56 GMT

Helou,

I'm trying to make radar graph with proc gradar. I need to change axis range and legend. Unfortunately, I if I use axis statement, it doesn't affect to major ticks. There is following example in SAS support pages for this modifying, but it does work only partially:

proc format library=library;

value mnth

1="Jan/Feb" 2="Mar/Apr" 3="May/Jun"

4="Jul/Aug" 5="Sep/Oct" 6="Nov/Dec";

run;

data goals;
   input month Division $ value @@;
   format month mnth.;
   format value percentn7.0;
datalines;
1 Parts .43 1 Tools .82
2 Parts .86 2 Tools .32
3 Parts .70 3 Tools .65
4 Parts .35 4 Tools .52
5 Parts .84 5 Tools .62
6 Parts .55 6 Tools .43
;
run;

goptions reset=all border hsize=5.15in vsize=4.2in;

axis1 order=(0 to .4 by .4, .6 to 1 by .2) value=(height=3pct c=blue tick=1 "");
axis2 order=(0 to .4 by .4, .6 to 1 by .2) value=none;

proc gradar data=goals;
   chart month / sumvar=value
      staraxis=(axis1 axis2 axis2 axis2 axis2 axis2)
      noframe height=3.25
      starinradius=0
      overlayvar=division;
run;
quit;

Labels are blue in axis1, but I got only labels 0.32, 0.59 and 0.86. In legend there is problem too, because line and tex are limited. I'm using SAS enterprice guide 4.3.0 and sas 9.21.

Support for the axis statement order= option was added to gradar in SAS 9.3.

Since you are using SAS 9.21, you do not have that functionality yet.

Here is a little more detail and an example of the new feature in 9.3:

Thanks for the information, Robert. Is there any posibility to change legend (position, label...) in the same way that it is possible in for example in bar chart?

I'm not sure off-hand (I don't use radar charts very often). What have you tried, and what results did you see (if any)?

I did some more checking, and found that gradar supports a 'nolegend' option, but other than that does not support any legend control. It does not honor a legend= option. I have entered a request to hopefully get that added in the future.

Hi Robert,

That was also my conclusion. So Proc Gradar makes legend automatically, and only posibility is use annotate, if user wants to make legend in the different way. I hope they will add legend option in future, because it is inside other graphs.

Since a bar chart will give you the control that you'd like to have, why not use a bar chart? Bar charts far exceed the information conveyance of a radar chart - http://www.perceptualedge.com/articles/dmreview/radar_graphs.pdf
