Attribute map not mapping to correct groups

JacquesR — Mon, 05 Oct 2020 21:34:56 GMT

Hi all

Here is some data from a Wikipedia page:

data polls;
input Date $15. @16 Polling_Organisation $21. @38 For F_LCL F_UCL Against A_LCL A_UCL Predicted_Outcome $ 9.;

;
run;

This is the attribute map:

DATA _AttrMap;
    LENGTH value $ 9 FillPattern $ 2 lineColor $ 5;
    INPUT ID $ Value $ FillPattern $ lineColor $;
    DATALINES;
    hbar Against   L1 black
    hbar For       R1 black
    hbar Undecided X1 black
    ;
RUN;

And finally, this is how I plot it (please excuse the caps):

ODS GRAPHICS /WIDTH=1000 HEIGHT=600 MAXLEGENDAREA=100
              IMAGENAME="Polls"
              attrpriority=none;
PROC SGPLOT
    NOBORDER
    NOCYCLEATTRS
    DATA=polls
    DATTRMAP=_AttrMap
    ;
    /* Put Polling_Organisation in the Yaxistable */
    YAXISTABLE Polling_Organisation
               /LOCATION=INSIDE
                POSITION=LEFT
    ;
    XAXIS LABEL="Percentage For/Against (Undecided not shown)" VALUES=(-100 TO 100 BY 10);
    HBARPARM 
        CATEGORY=Date
        RESPONSE=For
       /NOFILL FILLPATTERN
        GROUP=Predicted_Outcome
        GROUPDISPLAY=CLUSTER ATTRID=hbar
        GROUPORDER=DATA
        LIMITLOWER=F_LCL 
        LIMITUPPER=F_UCL
        LIMITATTRS=(COLOR=Black)
        NAME="Leg"
    ; 
    HBARPARM 
        CATEGORY=Date
        RESPONSE=Against
       /NOFILL FILLPATTERN
        GROUP=Predicted_Outcome
        GROUPDISPLAY=CLUSTER ATTRID=hbar
        GROUPORDER=DATA
        LIMITLOWER=A_LCL 
        LIMITUPPER=A_UCL
        LIMITATTRS=(COLOR=Black)
    ; 
    KEYLEGEND "Leg" /TITLE="Poll outcome";
    REFLINE -50 50 /AXIS=X LINEATTRS=(PATTERN=ShortDash);
RUN;

Everything works, except that the legend is not mapping the correct pattern to the correct group value (see below).

What am I missing?

thanks

Have you printed your data sets to ensure that you have the values that you think you have?

Re: Attribute map not mapping to correct groups

JacquesR — Tue, 29 Sep 2020 02:03:50 GMT

I coped the datalines from a proc print.

Apologies. I started writing this yesterday, and then loaded the post from the website's autosave. I forgot to change this:
Polling_Organisation $21.
However, that does not change the data needed for the plot (Polling_Organisation appears in the yaxis table, but is not the grouping variable).

I have updated the original to include that, so that Polling_Organisation is read properly.

I do not believe controlling the sgplot hbarparm fillpattern with dattrmap is supported yet. (If you have seen documentation indicating that it is supported, let me know and I'll check more into it.) The patterns you were seeing were just the default ones (which happened to almost correspond to the ones you were specifying, but in the wrong order).

Since that technique is not supported, you'll have to use a more indirect/hard-coded/order-dependent technique, such as using a styleattrs statement:

styleattrs datafillpatterns=(X1 R1 L1);

Here's a modified version of your code, using styleattrs to control the patterns. I've also changed your dattrmap colors to make it easier to see if they're affecting the graph:

data polls;
length Date $16 Polling_Organisation $50 Predicted_Outcome $9;
infile datalines dlm=':';
input Date Polling_Organisation For F_LCL F_UCL Against A_LCL A_UCL Predicted_Outcome;
datalines;

Thanks @GraphGuy

When no one answered, I tried reaching out to SAS tech support, and they did confirm what you stated above: This is not supported as yet, which is a pity.

They pointed me to a proc template example(https://support.sas.com/kb/45/663.html), which I was able to use to get the desired outcome:

proc template;
    define style mypatterns;
    parent=styles.listing;
/* The GraphBar element must be included with the
FILLPATTERN option in order to use fill patterns. */
  style GraphBar from GraphComponent / 
  displayopts = "fillpattern"; 

/* Fill patterns are defined using the FILLPATTERN 
style element attribute. 
COLOR is used for the bar fill colors
CONTRASTCOLOR is used for the line colors */

style GraphData1 from GraphData1 / 
    FillPattern = "X1"
    ContrastColor=black
; 
style GraphData2 from GraphData2 /
    FillPattern = "R1"
    ContrastColor=black
; 
style GraphData3 from GraphData3 / 
    FillPattern = "L1"
    ContrastColor=black
; 
end;
run;
