I facilitated a class of 7 professionals about histogram and told everyone that a histogram can only have 1 category, but somebody said that with overlay histogram you can have multiple categories on 1 histogram. Am I wrong to say that there can only be 1 category in a histogram or was he referring to a different type of histogram?
Both right: A single histogram is a count of something spread across various bin arrangements. There is only one histogram in a histogram, but we can have several histograms present on the same graph. Advanced paint programs offer views of the color values in a picture that overlay three histograms (red, green, blue) into a single space.
@AngleWyrm-paused,
Thank you so much for the clarification. Now I have a much better understanding of histograms.
