    General statistical procedure for visualization of discharge fluctuations is presented in the paper. It implies mapping of chosen statistical parameter characterizing local brightness variation. It is shown that Shannon entropy that is adopted from the information theory is the most relevant parameter to describe uncertainty degree. Special processing was applied to suppress effect of optical path sensitivity. Resulting maps shows fluctuation space distribution. Their application in investigation of discharge structure is demonstrated on an example of thermal plasma jet.
