ensure that two histograms have same bin sizes

csetzkorn — Fri, 03 Feb 2017 14:11:06 GMT

I am using this code:

title1 "&Title.";
proc sgplot data=WORK.TempGraphData;
	density X / type=normal lineattrs=(color=red) legendlabel='Bla';
	density Y / type=normal lineattrs=(color=blue) legendlabel='Bla';
	histogram X / transparency=0.75 fillattrs=(color=red) legendlabel='Bla';
	histogram Y / transparency=0.75 fillattrs=(color=blue) legendlabel='Bla';
	keylegend / location=outside position=bottom;
	xaxis label="Normal Curves";
run;

but the 2 histograms' bin sizes appear to be very different. can I force the rendering to use the same bin sizes in both diagrams?

you mean the width of the bins right? 🙂

Use the binwidth= option as described at the bottom of the blog post here:
