Re: Literal Arrays

There are several differnt ways of doing this.
This morning a response was sent sent to ncl-tal that was
similar to your question.

The response was:
===============================
A minor variation of

Example 2 at http://www.ncl.ucar.edu/Applications/xy.shtml

     nv = 2 ; number of variables to be plotted
     nx1 = dimsizes(X1)
     nx2 = dimsizes(X2)
     N = max( (/nx1,nx2/) )
     x = new( (/nv,N/), typeof(X1) )
     y = new( (/nv,N/), typeof(Y1) )

     x(0,0:nx1-1) = X1
     x(1,0:nx2-1) = X2
     y(0,0:nx1-1) = Y1
     y(1,0:nx2-1) = Y2

     plot = gsn_csm_xy (wks,x,y,res)
===============================

So, by analogy:

     nv = 4 ; number of variables to be plotted
     nx1 = dimsizes(mvdc1)
     nx2 = dimsizes(mvdc2)
     nx3 = dimsizes(mvdc3)
     nx4 = dimsizes(mvdc4)

     N = max( (/nx1,nx2,nx3,nx4/) )
     x = new( (/nv,N/), typeof(X1) )
     y = new( (/nv,N/), typeof(Y1) )

     x(0,0:nx1-1) = mvdc1
     x(1,0:nx2-1) = mvdc2
     x(2,0:nx1-1) = mvdc3
     x(3,0:nx2-1) = mvdc4

     y(0,0:nx1-1) = qc1
     y(1,0:nx2-1) = qc2
     y(2,0:nx1-1) = qc3
     y(3,0:nx2-1) = qc4

     plot = gsn_csm_xy (wks,x,y,res)
