overlay series curves

[dustychair]

Hi all,

I am trying to draw overlayed series (Actually I do want to use scatter but I couldn't draw curves of scatter plots) for two groups but I am getting athird line. You can find my code below and the resulting graph. Could you help me to get rid of this third line and make one curve black the other red? Thank you!

proc sgplot data=TIF_TCC_R_l_g noautolegend;
where form in ("Model 1.0", "Model 1.75");
series y=TIF x=ability/ legendlabel= 'Model 1.0' ;
series y=TIF x=ability/ legendlabel= 'Model 1.75' ;
xaxis values =(-9 to 6 by 0.5); ;
yaxis display=(noline noticks ) grid;
yaxis label="Information";
keylegend / title ="Reading 12 graph" sortorder=ascending location=outside position=bottom across=1;
