Another bug with SGPLOT: UNIFORM=ALL does make X axes uniform?

WillTheKiwi — Thu, 29 Aug 2019 01:51:06 GMT

I want to make two graphs via by-processing with the same scaling of X and Y axes. SGPLOT resolutely refuses to make uniform scaling of the X axes with UNIFORM=ALL, UNIFORM=SCALE and UNIFORM=XSCALE. The Y axes are made uniform, however. Here's the code, and attached is the output. Sorry I can't easily include the dataset. In any case, it's probably something arcane to do with the attributes or something that I have got wrong. (BTW, I used log transformation and back-transformed, in case anyone picks up on the non-uniformity.) And can anyone see why I don't get red outlines on the markers?

Thank you!

Two ways to accomplish what you want.

1. Use PROC SGPANEL. The PANELBY statement produces different plots for each level of a grouping variable, but you can use the UNISCALE= option to equate the ranges of the X axis, Y axis, or both.

2. Use PROC MEANS to get the min and max value of the data across all levels of the BY-group variable. Use those values in your current code as arguments to the MIN= and MAX= options on the XAXIS statement.

You could use SAS/Graph Proc Gplot - its 'uniform' option keeps both the x and y axes uniform, across by groups.

Here's an example:

proc sort data=mapsgfk.uscity out=my_data;
by statecode;
run;

proc gplot data=my_data uniform;
by statecode;
plot lat*long;
run;

Thanks, Rick, but according to the documentation for SGPLOT, I should get uniform X axes:

ALL specifies that both the legend group values and the axis scaling are shared between all of the levels of the BY variable or variables.

I don't want to use a different plotting procedure, having spent hours-no, days, if you add it all up-getting just a rudimentary knowledge of how to get what I want out of SGPLOT.

Thanks, Robert. As I said to Rick, I don't particularly want to switch plotting procedures, having put in a lot of time to get the code right for SGPLOT.

There is an issue in the proc, but I'm going to give you a simple fix. Add this line to your SGPLOT:

xaxis type=linear;

Let me know if that works for you.

Thanks!
