Hi I keep getting this error and I can't figure out why...

This is the code I'm using... notice the axis2 is the same for both Plot and Plot2 statements. I'm using the Plot statements because each graph has it's own annotation. Each plot runs fine by itself, but together the horiz statements are seen as different. I tried just taking out the haxis statement in the second plot but that gives me the same problem. Any help is appreciated. Thanks

title1 'State CL for PT-Math';

axis1 label=none
minor=none
offset=(.1,.10);

axis2 order=(0 to 50 by 5)
label=('%Time spent in Subject')
minor=none;

symbol1 interpol=none color=black value=dot height=1.5;

proc gplot data=test ;
plot yvar*Trate /annotate=Tanno nolegend haxis=axis2 vaxis=axis1 ;
plot2 yvar*Prate / overlay annotate=Panno nolegend haxis=axis2 vaxis=axis1 ;
run;

ERROR: Horizontal axis variables on PLOT and PLOT2 statements must be the same. Variables do not match in plot pair 0.

The horizontal axis need to use the same X variable. Your code uses two, TRATE and PRATE.

One approach to getting what I believe you are attempting is to create a single X variable and a categorical variable to differentiate.

Quick and dirty example:

data newtest (keep=yvar rate ratetype);
set test;
rate=trate;ratetype="T";output;
rate=prate;ratetype="P";output;
run;

proc gplot data=newtest;
plot yvar*rate=ratetype /haxis=axis2 vaxis=axis1;
run;
quit;

Since you don't have any details on the annotate I'm not including it.

Thanks Ballardw,

That does give me the plots on one chart, but what I need is to get two confidence limits on one chart! I've inserted the code with data (not all the states for brevity!) - so you can simply run it and see what I mean. I'd like both plots to be annotated. Would I try and do the same trick you gave me with the annotate code, so there is only one annotation for all the data instead of 2?

Have you tried the I=R type symbols?

I think 2 symbol statments with i=RLCLI95 or i=RLCLM95 depening on whether you're looking for limits of individual or mean estimators.

The online help for Gplot should have an example called Plotting Two Variables which does a regression and confidence limits around one set of variable pairs.

Two separate symbol statements with different colors and symbols should overlay.

One big advantage is you just drop the data in and let the regression be handled by Gplot. If you're confidence limits come from some thing other than linear, quadratic or cubic regression, then I'm out of ideas. I think a properly constructed annotate data set shoulc still work but I haven't time to figure out how to display it at the moment.

Thanks - yes I have to use the limits from the data set since I used 80 plus replicate weight samples from the data to derive the CL. I'll give your suggestions a whirl - thanks so much for taking the time to share your thoughts. At least I have a direction to try now.

If the data are more complicated then I understand.

It may be that the better idea would become to create additional "rate" variables if you have the confidence limits for the X values.

(Pseudo code).
rate=trate;ratetype="T";output;
rate=trateuppercl;ratetype='TCU';output;
rate=tratelowercl;ratetype='TCL';output;
rate=prate;ratetype="P";output;
rate=prateuppercl;ratetype='PCU';output;
rate=pratelowercl;ratetype='PCL';output;


And appropriate symbol statements to join the limits.

Hi Ballardw,

Just for closure, I thought I'd give you an update... I used your suggestion plus did something quick and dirty which got the results I needed, but it ain't pretty! Sometime I may go back and do this right, but for now it works and I can move on. Below is the end program that gives me what I want. Thanks again for your help!

oops last statement group should be... (take out the nolable and make it nolegend)
