superscript in data label

[JacquesR]

I am trying to create a plot with data labels on specific points, with 10^-7 displayed in the data label.

DATA D_DailyDataForPub;
    SET D_DailyDataForPub;
    IF Date EQ '17OCT2020'D THEN DO;
/* I tried using superscript, but it did not work: */
/*
        MaxLabelGE=CATX(" ","17 Oct:",PUT(_g_11dfx5ynpb_GTExt_2020_10_20,8.1),CATT("x 10","(*ESC*){super -7}"));
        MaxLabelCR=CATX(" ","17 Oct:",PUT(_g_NZCR__GTExt_2020_10_20     ,8.1),CATT("x 10","(*ESC*){super -7}"));    
        MaxLabelER=CATX(" ","17 Oct:",PUT(E_R_GTExt_2020_10_20          ,8.1),CATT("x 10","(*ESC*){super -7}"));         
*/
/* Then I tried unicode */
        MaxLabelGE=CATX(" ","17 Oct:",PUT(_g_11dfx5ynpb_GTExt_2020_10_20,8.1),CATT("x 10","(*ESC*){unicode '207B'x}","(*ESC*){unicode '2077'x}"));
        MaxLabelCR=CATX(" ","17 Oct:",PUT(_g_NZCR__GTExt_2020_10_20     ,8.1),CATT("x 10","(*ESC*){unicode '207B'x}","(*ESC*){unicode '2077'x}"));    
        MaxLabelER=CATX(" ","17 Oct:",PUT(E_R_GTExt_2020_10_20          ,8.1),CATT("x 10","(*ESC*){unicode '207B'x}","(*ESC*){unicode '2077'x}"));         
    END;
    ELSE DO;
        MaxLabelGE=" ";
        MaxLabelCR=" ";
        MaxLabelER=" ";
    END;
RUN;
PROC FREQ
    DATA=D_DailyDataForPub;
    TABLE MaxLabel:;
RUN;

When I use proc freq, I get the desired result:

MaxLabelGE	Frequency	Percent	Cumulative Frequency	Cumulative Percent
17 Oct: 380861.3 x 10⁻⁷	1	100.00	1	100.00
Frequency Missing = 91

However, the plot does not display properly:

PROC SGPLOT
    NOBORDER
    DATA=D_DailyDataForPub;
    YAXIS LABEL="Log of Raw search probability (x 10(*ESC*){unicode '2077'x})" VALUES=(0 TO 13 BY 1) RANGES=(0-1 5-13);
    XAXIS TYPE=TIME FITPOLICY=SPLIT INTERVAL=Day ;*VALUESFORMAT=DATETIME10.;
    SERIES X=Date Y=LogElection   /DATALABEL=MaxLabelGE;
    SERIES X=Date Y=LogCannabis   /DATALABEL=MaxLabelCR;      
    SERIES X=Date Y=LogEuthanasia /DATALABEL=MaxLabelER;      
RUN;

Note that the superscript in the y axis label does work.

I have looked at:

But I can't get this to work.

Any help would be appreciated.
