How to enter 2 columns from an array into 1 input?

Loaded in a set of data containing 3 columns of info.

column 1 is H (height) and 2 and 3 are measurements (say of R) where the x values are col 2 and y values are col 3.

i need to plot a graph where h is the horiz axis and R on the vertical axis.

how would i go about making essentially the x and y 1 axis so h can be the other?

[ax,h1,h2]=plotyy(h,x,h,y)

i dont completely understand where the 'g' and 'r' are coming from.

[Azzi Abdelmalek]

they are just color red and green, if you want

 plotyy(h,x,h,y)

 help plotyy

[Tyler]

ok that worked perfectly. Im doing multiple plots, how would i denote them as say figure 1, fig 2, fig3 ,etc.

when i do them all (the multiple plotyy's) i get a figure 1 and that is it.

edit: if i can i want them to show up at the same time and not interfere iwht each other.

[Azzi Abdelmalek]

do you mean

 plotyy(h,x,h,y);
 figure
 plotyy(h,x1,h,y1)
 figure
 plotyy(h,x2,h,y2)

I wonder if you want

plot(sqrt(x.^2 + y.^2), h);

[Image Analyst]

But he wanted h on the horizontal axis and R on the vertical. I guess R = sqrt(x.^2 + y.^2). So wouldn't it be plot(h, sqrt(x.^2 + y.^2))?

[Walter Roberson]

Right. I was reading off from the last line of the Question which implicitly used the other order.
