%Stacking two sets of impulse responses in one graph. See fn_multigraph1_ver2.m.
%imf1, imf2 -- each has 3 dimensions. Row: horizon; column: 'nrow' variables; 3rd dim: 'ncol' situations such as shocks or regimes.
% imf#: row: "nstp" time horizon (in the graphics), column: "nrow "variables (row in
% the graphics), 3rd D: across "ncol" different situations (column in the graphics)
% xlab: x-axis labels on the top
% ylab: y-axis labels on the left
% tstring: string for time (e.g., month or quarter) -- x-axis labels at the bottom
% YTickIndx: 1: enable YTick; 0: disable;
% To get a better picture, it is sometimes better to set YtickIndx to zero.
% scaleIndx: 1: enable scale along Y-axis; 0: disable
% nrowg: number of rows in the graph
% ncolg: number of columns in the graph
