        Valid keyword options are:
        x, x0, x1, y, y0, y1, width, height, pen, brush
        
        x specifies the x-position of the center of the bar.
        x0, x1 specify left and right edges of the bar, respectively.
        width specifies distance from x0 to x1.
        You may specify any combination:
            
            x, width
            x0, width
            x1, width
            x0, x1
            
        Likewise y, y0, y1, and height. 
        If only height is specified, then y0 will be set to 0
        
        Example uses:
        
            BarGraphItem(x=range(5), height=[1,5,2,4,3], width=0.5)
