I want to plot some residuals as positive and negative values. Is there a way to make negative values to be directed downwards and positive to be directed upwards, but for negative values symbols to be positioned downwards. Using arrows for negative values and making the angle 180°, it's just rotate the symbol, not making to start from the level of the point. In other words, could the symbol be positioned realtive to the point (given with x,y coordinates) below, as for the labels. Thanks, Miran.
