How to read the Histogram. A histogram is a graphical representation of the pixels exposed in your image. The left side of the graph represents the blacks or shadows, the right side represents the highlights or bright areas and the middle section is mid-tones (middle or 18% grey).
STEP 2: Decide on the bin values. The bin column allows you to choose the class intervals for the histogram. If you do not include a bin column Excel will choose the class intervals. It is not recommended to let Excel choose. For the first bin value Excel chooses all data items less than and equal to this value.TEP 3: Use Excelâs histogram tool. Type the bin values into the excel spreadsheet. (I usually copy and paste the data column of interest into a new worksheet but it is not necessary.) Look at the first two columns of the worksheet labeled Histogram in the Excel file House Sales in Kaleen 2003.
