  A candela plot is a plot of luminous intensity, or flux per solid angle. In photometric units, a luminous intensity plot is in units of candelas, or lumens per steradian. In radiometric units, the corresponding quantity is called intensity, and has units of watt/steradian. Candela plots are commonly used in the design of illumination systems. (e_p8[x
