Proc SGPLOT data display issue

Dregerator — Tue, 31 May 2022 17:12:42 GMT

Hi,

I'm trying to create a series plot from 1 to 400 dilution with this data, however, any time I try to create a discrete y-axis value from 0-100 data values don't appear on the graph.

PARAMCD	PCT	DIL
Test1	25.5	1
Test5	36.4	1
Test6	30.6	1
Test8	41.7	1
Test9	44.0	1
Test100	43.3	1
Test1	40.6	2
Test5	60.3	2
Test6	46.2	2
Test8	49.1	2
Test9	49.8	2
Test100	50.0	2
Test1	48.0	4
Test5	74.1	4
Test6	55.4	4
Test8	54.2	4
Test9	55.6	4
Test100	56.5	4
Test1	54.7	8
Test5	83.0	8
Test6	61.6	8
Test8	61.4	8
Test9	62.1	8
Test100	61.6	8
Test1	60.3	16
Test5	90.6	16
Test6	68.7	16
Test8	66.1	16
Test9	66.3	16
Test100	66.5	16
Test1	74.5	80
Test5	97.6	80
Test6	85.9	80
Test8	83.5	80
Test9	81.2	80
Test100	83.0	80
Test1	91.1	400
Test5	100.0	400
Test6	96.0	400
Test8	95.1	400
Test9	94.6	400
Test100	95.5	400

this is what I'm trying to do with code

proc sgplot data=graph;
series x=dil y=pct/group=paramcd;
xaxis values=(1 2 4 8 16 80 400 2000) label="Dilution Level" ;
yaxis values=(0 to 100 by 10) label="% Negative";
run;

Cosmetic stuff such as tick markers appearing on x-axis is also another issue. Any help is appreciated.

Can you please show us the output that you get, and explain what is wrong with the output? (Use the "Insert photos" icon to include screen captures in your reply)

this first is with the y-axis condition. and the second one is without it. I just want a line graph for each of the parameter at the specific ticks to tell me what the percentage is at that tick. Right now, the percentage is going all over the place and I want it to go from 0-100 so we can interpret if values go up and down over dilutions.

I even proc sort before it

proc sort data=graph;
by dil;
run;

proc sgplot data=graph;
series x=dil y=pct/group=paramcd;
xaxis values=(1 2 4 8 16 80 400 2000) label="Dilution Level" ;
*yaxis values=(0 to 100 by 10) label="% Negative";
run;

In your SAS data set, according to PROC CONTENTS, is variable PCT numeric or text?

When I create a data step with your text and PCT is a numeric variable:

data have;
   input PARAMCD $ 	PCT 	DIL   ;
datalines;
Test1 	25.5 	1
Test5 	36.4 	1
Test6 	30.6 	1
Test8 	41.7 	1
Test9 	44.0 	1
Test100 	43.3 	1
Test1 	40.6 	2
Test5 	60.3 	2
Test6 	46.2 	2
Test8 	49.1 	2
Test9 	49.8 	2
Test100 	50.0 	2
Test1 	48.0 	4
Test5 	74.1 	4
Test6 	55.4 	4
Test8 	54.2 	4
Test9 	55.6 	4
Test100 	56.5 	4
Test1 	54.7 	8
Test5 	83.0 	8
Test6 	61.6 	8
Test8 	61.4 	8
Test9 	62.1 	8
Test100 	61.6 	8
Test1 	60.3 	16
Test5 	90.6 	16
Test6 	68.7 	16
Test8 	66.1 	16
Test9 	66.3 	16
Test100 	66.5 	16
Test1 	74.5 	80
Test5 	97.6 	80
Test6 	85.9 	80
Test8 	83.5 	80
Test9 	81.2 	80
Test100 	83.0 	80
Test1 	91.1 	400
Test5 	100.0 	400
Test6 	96.0 	400
Test8 	95.1 	400
Test9 	94.6 	400
Test100 	95.5 	400
;

proc sgplot data=have;
   series x=dil y=pct/group=paramcd;
   xaxis values=(1 2 4 8 16 80 400 2000) label="Dilution Level" ;
   yaxis values=(0 to 100 by 10) label="% Negative";
run;

So one suspects that your PCT variable is character. So the YAXIS values don't work with your data.

Because you have such a wide range, 1 to 2000 for the Xaxis there may not be enough space on that axis as linear to show 1, 2, 4 and 8. You can try FITPOLICY=STAGGER on the Xaxis and if your graph width space is large enough you might see them. Or use TYPE=LOG on the Xaxis to create a logarithmic scaled axis.

What does the log show?

Also does PCT have a format attached?

If the data fluctuates, there's nothing you can do about that, that's the data.

But it should show up for the 0 to 100.
