Draws a variable width histogram.
Does not calculate data, it is just a drawing utility.
Draws histogram with defined x, so data length(data)=length(x)-1, or, if lengths are equal, bars are centred at x.
HANDLES = VWHIST(X,Y,DX,DY,DIREC,FaceColor,EdgeColor)
Just what I needed.
it will be more nice if we can help with this..teenagers
