Good morning, mjj. I have a work sheet that will do this. Every time I try to type it into this comment block, when I look at the Preview, what I see is not what I typed. So, I give up. Send me an email and I will email you the little program. Jim Herod jherod@tds.net

Data points on same graph - example

Try this as an example: > restart:with(stats):with(statplots):with(plots): > Data := [[1, 1], [2, 4], [3, 9], [4, 16], [5, 25], [6, 36], [7, 49], [8, 64], [9, 81], [10, 100]]; > X:=[seq(Data[i,1],i=1..nops(Data))]; > Y:=[seq(Data[i,2],i=1..nops(Data))]; > da_fit:=fit[leastsquare[[x,y],y=a*x^2+b*x+c]]([X,Y]); > ptplt:=scatterplot(X,Y,symbolsize=20,color=green): > crvplt:=plot(rhs(da_fit),x=0..10): > display({crvplt,ptplt}); > int(x^2,x=0..10); Regards, Georgios Kokovidis Dräger Medical

Use pointplot and display (Maple 10)

> f := Spline(xydata, x);

> p1 := pointplot(xydata, color=blue, symbolsize=15):

> p2 := plot(f, x=-5..5, y=-5..5):

> display([p1,p2]);
