Kelvin (K) is the only scale that has a numeral value assigned to absolute zero. 
        
             
        
        
        
Although there isn’t a picture a graph can be misleading when it doesn’t start at zero, it doesn’t give accurate information, it skips too many numbers, the vertical scale is too big or too small. Hope this helps
