function fn_mseriesgraph(ydate,keyindx,rnum,cnum,q_m,xlab,ylab,tlab)
% fn_mseriesgraph(ydate,keyindx,rnum,cnum,q_m,xlab,ylab,tlab)
% Graph actual series or point forecasts or both (annual or monthly or quarterly)
% with multiple series in one subplot.
%
% ydate: T-by-n+2-by-h series data with dates in the first 2 columns in the order of year and month (or quarter).
% T: the length of an individual series.
% n+2: n series plus the first 2 columns indicating dates.
% h: the number of sereies on the 3rd dimension, put in the same subplot as in each of the n series.
% Thus, the first 2 columns in the 3rd dimension can be NaN while
% some elements are also allowed to be NaN if no data are available.
% keyindx: index for the variables to be graphed
% rnum: number of rows in subplot
% cnum: number of columns in subplot
% q_m: if 4 or 12, quarterly or monthly data
% xlab: 1-by-1 x-axis label for what conditions imposed; e.g., conlab = 'All bar MS shocks inspl'
% ylab: string array for the length(keyindx)-by-1 variables
% tlab: 1-by-1 title label for (e.g., as of time of forecast)
